extracted from the exceedance curve (see Figure S8 in the Methods). Purple curve
indicates mean-unbiased exponential IRLS trend for these exceedance frequencies. Note:
the curves are exponential, but the curvature is indistinct for many sites due to the scatter

stage flow frequency (number of days with mean daily discharge equaling or exceeding
the long-term average QFS each year). The purple exponential curve represents the
mean-unbiased exponential trend in annual flood stage flow frequency. The

1. Background
Cross-sectional discharge (Q) – or the volume of flow (m3/s) that is carried in a river channel at
any given level of stage (the water surface level, noted by the USGS as gauge height G) – is
computed as:
Q = AV
(1a)
where A is measured cross-sectional channel area (m2) and V is measured cross-sectional average
flow velocity (m/s), for the specified level of stage. Flooding occurs when the water level rises
above the flood stage. The US National Weather Service defines flood stage as “an established
gauge height for a given location above which a rise in water surface level begins to create a
hazard to lives, property, or commerce” [National Weather Service, 2014]. Flood stage is therefore
the chosen water level for flood warnings, and is “not necessarily the same as bankfull stage”
[National Weather Service, 2014]. The volume of discharge that can be carried in a river channel
cross-section at flood stage (QFS) can be computed as:
QFS = AFSVFS
(1b)
where AFS is the channel cross-sectional area at flood stage (m2), and VFS is the cross-sectional
average flow velocity at flood stage (m/s) (Fig. S1). This volume of flow that can be carried within
the channel at flood stage can also be described as the channel capacity at flood stage (CC):
CC = QFS

stage (QFS). Flood stage is represented as a horizontal dotted line, and channel
datum below the channel is indicated as a horizontal dashed line.
Because channel capacity may change over time, we refer to the average cross-sectional
discharge at flood stage, over a given period, as QFS .
The frequency with which flooding occurs – which we term the flood hazard frequency (FHF)
– depends on two factors: the capacity of the local channel cross section to carry the flow
3/235
delivered from upstream (the channel capacity), and the frequency distribution of flows generated
from the upstream basin. Thus flood hazard frequency can be altered by changes in a river's flow
frequency distribution, its channel capacity, or both:
(i) Flow frequency distributions may change in response to: a) climatic shifts that affect the
phase, intensity, duration, and timing of precipitation, snowmelt, and/or runoff; b) anthropogenic
modifications to basin water delivery (e.g., damming, upstream extraction, diversions, regulation);
and c) landscape changes (e.g., agricultural conversion, deforestation, urbanization) that alter
storm runoff. Trends in flow frequency may affect flood hazard frequency at a cross section even
under stable conditions of channel capacity.
(ii) Channel capacity (the volume of flow carried at flood stage) may change due to (a)
shifts in the cross-sectional channel area at flood stage (AFS) caused by bed aggradation/
degradation or channel narrowing/widening, and/or (b) changes in the cross-sectional average
flow velocity at flood stage (VFS), which is controlled by depth, width, and boundary roughness
(e.g., grain size and bank vegetation). Both AFS and VFS can also be affected by climatic variability,
anthropogenic flow alterations, bed grain size coarsening and fining, vegetation growth and
removal, and/or landscape changes that modify the balance between sediment erosion and
deposition in the channel. Trends in channel capacity may affect flood hazard frequency at a cross
section even under stable conditions of flow frequency.
Below we outline how these two distinct causes of change in flood hazard frequency can be
quantified independently, in order to assess their respective impacts on flood hazard.
2. Data and Initial Filtering
Our source data are: flood stage estimates, mean daily streamflow records, and manual USGS
field measurements of cross-sectional channel discharge, cross-sectional channel area, and crosssectional average flow velocity.
(i) Flood stage values are provided by the US National Weather Service [National Oceanic and
Atmospheric Administration, 2014].
(ii) Historical mean daily streamflow records are stored by the US Geological Survey (USGS)
and made publicly available online [U.S. Geological Survey, 2014d]. In this analysis, we used mean
daily streamflow data rather than annual peak flow data because we sought to characterize flows
that could potentially occur more frequently than once per year. We retained only sites with mean
daily streamflow records that were at least 90% complete. For the 401 sites, the mean record
completeness is 99.7%, and the mean record length is 57.1 years.
(iii) Manual field measurements are made by the USGS at more than 7,000 active stream
gauges across the USA to maintain rating curves between stage and discharge [U.S. Geological
Survey, 2014b]. In stream gauging, rating curves are used to convert stage measurements to
estimates of discharge flowing through the river channel cross-section. To develop the rating
curves, the USGS make manual field measurements of channel dimensions (cross-sectional
channel area and width (W)) and cross-sectional average flow velocity, and thereby calculate
stream discharge from equation (1a) [Carter and Davidian, 1968]. These measurements are
repeated regularly to ensure that the rating curves are accurately maintained. Archives of these
manual field measurements are publicly available online [U.S. Geological Survey, 2014c]. We
retained only gauging sites with a minimum of 10 repeat channel cross-sections at each location
4/235
after all filtering (described in section 4 below). The mean number of measurements for the 401
sites is 40 channel cross-sections, and the mean record length is 37.3 years.
Following all of the filtering steps (section 4), we retained only sites where the discharge and
manual field measurement records both spanned at least 20 years between 1 January 1950 and 30
June 2013.
3. Evaluation of flow modification
To assess channel capacity and flow frequency effects in the context of climate change, we
divided our sites into categories of flow modification that indicate whether flow alterations might
mask the influence of climate on streamflow generation and thus flood hazard frequency. We
characterized the degree of flow modification for each site as follows:
(i) We carefully scrutinized the mean daily streamflow time series [U.S. Geological Survey,
2014d] for each site on both linear and logarithmic axes (Fig. S2), since the linear form of the
hydrograph is most useful for distinguishing any changes in the highest flows, while the
logarithmic form amplifies any differences in low flows and aids in detecting water withdrawals or
diversions.
(ii) We evaluated any entries under “remarks” in the Annual Water Data Reports [U.S.
Geological Survey, 2014a], for all of our sites where these reports were available. The remarks
provide information on the causes of flow modification (e.g., diversions, dams, different types of
regulation, power plants, lakes, mills), and on the magnitude/type of modification (e.g.,
some/considerable regulation, permanent/ intermittent regulation, regulation of low/high flows,
size of diversions).
(iii) We screened maps and aerial images covering each basin in Google Earth, to detect any
evidence of human impacts (e.g., storage, artificial diversion, or any activities in the basin) that
could alter natural flows. Many of our sites (93%) are also in the Geospatial Attributes of Gages for
Evaluating Streamflow (GAGES II) dataset [Falcone, 2011], which contains screening comments by
personnel from the National Water-Quality Assessment Program regarding evidence of
anthropogenic flow alterations. We cross-referenced our own screening remarks with the National
Water-Quality Assessment Program comments, when these were available.
Following these steps, we classified our sites into three relative categories according to their
degree of flow modification (Fig. S2):
• Sites where the magnitudes of flood peaks were clearly affected by flow modification
were classified as ‘Most modified’.
• Sites where flow modification was visible or reported, but did not appear to affect the
magnitudes of flood peaks, were classified as ‘Intermediate’.
• Sites where flow modification was not clearly detectable from the mean daily streamflow
data, not mentioned in the water reports, and not visible from the screening of maps and
satellite photos were classified as ‘Least modified’.

site, where low flows have been visibly modified, but the peaks have been
modified to a much lesser extent; and (c) the Neches River at Evadale (TX) is a
Most modified site where flow peaks have been capped by multiple upstream
reservoirs that became operational after the mid-1960s, and where low flows
have been visibly augmented.

4. Further filtering steps: manual field measurement location and consistency
We carried out several additional filtering steps to ensure consistency in manual field
measurements for the computation of channel capacity. In addition, in order to quantify changes
in QFS, AFS, and VFS in each cross-section (Fig. S1), we carried out tests to identify any manual field
measurements that had obviously not been made consistently in the same location over time.

Sioux River near Brookings, SD (Note: For consistency, the same site is used in
Figs. S3-S9). Flood stage is indicated by dashed vertical black line (2.74m). Dark
grey circles represent manual field measurements selected within a range of
half the flood stage depth on either side of flood stage, and were retained for
subsequent analysis (see section 4A). Open circles indicate measurements that
were omitted from the subsequent analysis because they fell outside this range
around flood stage.
The purpose of our paper is to quantify the effects of channel capacity and flow frequency
trends on flood hazard frequency at flood stage. However, manual field measurements of channel
capacity are rarely made exactly at flood stage, so measurements made over a wider range of
stages were used, based on a procedure that extrapolates channel capacity changes to flood
stage, as explained below. To maximize the available data for estimating channel capacity, while
minimizing potential errors in its estimation, we retained only measurements that were taken at
flood stage, plus or minus a range of half the channel depth. We measured channel depth at flood
stage by the difference between flood stage and the minimum stage value, excluding outliers (Fig.
S3). This range is wide enough to encompass a large number of manual field measurements, but
narrow enough to exclude measurements made at low flow, as well as those taken when the flow
was well above floodplain elevation, which are less relevant to the hydraulics at flood stage.
7/235
B- Within the Water Data Reports [U.S. Geological Survey, 2014a], under the section “gage”, we
identified:
(i) Weirs and artificial controls at the gauging location. These are hard structures in the river
channel that resist erosion and stabilize the stage-discharge relation, thereby facilitating the
measurement of discharge. They are used to eliminate or alleviate “the adverse effects of unstable
conditions due to shifting bed or banks, the formation of ice in winter, progressive growth of
aquatic vegetation during the summer, and other phenomena which at times affect the stagedischarge relation at low stages” [Carter and Davidian, 1968]. This means that they prevent part of
the channel from adjusting its cross-sectional shape. Thus, we removed any sites where either
weirs or controls were mentioned, since they would artificially limit changes in channel capacity.
(ii) Changes in manual field measurement location and gauge datum. The gauge datum is
the level plane that represents zero elevation of the stream gauge (Fig. S1). Its level is intended to
remain unchanged over the life of the gauging station, and therefore is selected well below the
estimated maximum scour depth [Kennedy, 1990; Kenney, 2010]. Changes in gauge location and
gauge datum are typically reported in the Water Data Reports, noted as follows: e.g, “Oct. 1975 to
Aug. 1983 crest-stage gage at site 500 ft upstream at different datum”. For every mention of a
change in datum or gauge location, we recorded the most recent year of the change, and
systematically removed any manual field measurements that were made in that year or any
preceding years. The exact date of change in datum/location was not always provided in the
reports, so we conservatively discarded the full year of data in which such a change occurred.
C- Within the USGS manual field measurements [U.S. Geological Survey, 2014c], we removed:
(i) Manual field measurements made in icy conditions. Such measurements are undesirable
because ice in the channel might affect inferred channel geometry.
• The data column meas_type describes the method used to suspend or place
measurement instrumentation into the water, and indicates discharge measurements
that were made through river ice (ICE).
• The data column control_type_cd describes the condition of the rating control at the
time of the measurement, and specifies when the control was covered by ice (CICE),
affected by anchor ice (AICE), or by shore ice (SICE). All measurements taken in icy
conditions were discarded.
(ii) Missing measurements. If any one of the Q, A, V, or W measurements had a negative, zero,
or missing value on a given date, we removed the entire collection of measurements (Q, A, V, and
W) made on that day.
(iii) Measurement inaccuracies. To remove any potential inaccuracies in Q, A, or V, we filtered
for potential measurement errors by calculating, following equation (1a):
Q
AV
(3)
and removing any measurements where this ratio was not equal to 1, within a range of ± 1%.
(iv) Measurements taken at a distance from the gauge:
• The data column chan_loc_cd specifies which measurements were made at the
gauge (ATGA), or at a different location upstream (UPST) or downstream (DNST) from
the gauging station. We deleted all measurements that were marked UPST or DNST.
8/235
•
The data column chan_loc_dist indicates the distance at which measurements were
known to have been taken from the gauging station. We removed all measurements
where the indicated values were larger than zero.
D- Visual verification of measurement location
Despite the above-mentioned indications regarding manual field measurement location in
the Water Data Reports and field measurement files, precise measurement locations are typically
missing from the data files for the majority of measurements. Manual field measurements are
often made at a distance from the principal gauging site, which is not an issue if the measurement
location is consistent over time. However, if the measurement location is variable, computed
trends in channel capacity will be incorrect. It is therefore vital that such measurements are
identified and excluded from the analysis.
Unfortunately, it is difficult to discern, using automated methods, where manual field
measurements are made, and scatterplots (e.g., Q versus G) do not always reveal these
inconsistencies in measurement location (e.g., Fig. S4a). Therefore, we visually cross-verified
scatterplots of W, A, and V versus G. This step was helpful for detecting likely changes in
measurement location. In particular, the presence of groups of outliers across the various
scatterplots is a strong indicator of shifts in measurement location (or datum). We systematically
removed these measurements.
For example, the scatterplot of Q v. G for site 06480000, Big Sioux River near Brookings, SD
(Fig. S4a), exhibits some scatter about flood stage, but does not obviously suggest that manual
field measurements were made in different locations. Close inspection of the scatterplots of W,
and A, versus G (Fig. S4b-c), however, reveals inconsistencies that suggest that measurements
were in fact made in different locations. We manually filtered manual field measurements where
the measurement locations were obviously inconsistent. File S2 provides full documentation of
these removed measurements (final scatterplots showing which measurements were discarded or
retained, following all filtering steps).

near Brookings, SD. Flood stage is indicated by the dashed vertical black line.
The scatterplot of cross-sectional channel discharge versus gauge height (a)
gives no indication that the manual field measurements come from multiple
measurement locations. By contrast, the scatterplots relating gauge height to
width (b) and cross-sectional area (c) clearly suggest the presence of different
measurement locations or measurement error at high values of stage. We
systematically cross-compared scatterplots at all sites, and retained only the
measurements that did not visibly belong to multiple measurement locations
(selecting only the most consistent-looking location, in cases where several
measurement locations were apparent - see File S2 for filtering of all 401 sites).
The dark grey circles represent retained measurements that are within a range
of half the flood stage depth on either side of flood stage (see Fig. S3), and that
do not obviously indicate different measurement locations. Open circles
indicate measurements that were outside range of half the flood stage depth
on either side of flood stage, and were excluded from subsequent analysis. The
four red circles indicate measurements that were within the range of retained
measurements but were discarded from subsequent analysis because they were
indicative of a different measurement location or measurement error.
5. Estimation of cross-sectional channel discharge, flow area, and average flow velocity at
flood stage from manual field measurements
For each site, we define the average value of Q, A, and V at flood stage ( QFS , AFS , and VFS ),
from the available manual field measurements. While flood stage values of Q, A, and V may vary
over time, QFS , AFS , and VFS are fixed values representing their averages over the entire period
10/235
of record. QFS is used to compute both the flow frequency and channel capacity effects (sections 6
and 7, respectively), while AFS and VFS are used to compute the trend in cross-sectional channel
area and cross-sectional average flow velocity at flood stage (section 8).

field measurements that were retained following filtering steps (as indicated in
Figs. S3-4). The grey curve represents the Loess fit to the measurements. The
interpolated values of QFS , AFS , and VFS at flood stage (ln(FS)=1.01) are
indicated by thin dashed grey lines.
To quantify these values, we used Loess, Locally Weighted Scatterplot Smoothing [Cleveland,
1979], which fits smooth curves through scatterplots, point by point, based on local iteratively
reweighted regression on nearby measurements. For each site, we converted the measurements
to metric units, and fit Loess curves relating the natural logarithms of Q, A and V (ln(Q), ln(A), ln(V))
to G (ln(G)). Loess fits a smooth nonparametric curve that systematically discounts the influence of
outliers (points with unusually large deviations from the rest of the data). The degree of smoothing
11/235
is controlled by the parameter α [Ripley, 2014]. We chose α=0.75 because it provided a good fit to
our data.
Using the predict.loess function from the R statistical programming language [Ripley, 2014]
and the defined values of flood stage (Section 2), we identified and recorded the y-axis values
where each curve intersected flood stage. Thus, we obtained the value of QFS from the ln(G)-ln(Q)
curve, (Fig. S5a), we obtained AFS from the ln(G)- ln(A) curve (Fig. S5b), and we obtained VFS from
the ln(G)- ln(V) curve (Fig. S5c) for each site.
6. Effects of streamflow trends on flood hazard ("flow frequency effect"), estimated from
mean daily streamflow data
A- Computing flow frequency
To isolate trends in flow frequency from changes in channel capacity, we quantified the
annual flood-stage flow frequency (FF) as the number of mean daily streamflow values in each year
that equaled or exceeded a fixed flood stage discharge:
FF = sum ( Q ≥ QFS )
(4)
where Q is each mean daily streamflow value, and QFS is the reference cross-sectional discharge
at flood stage for each site, determined in section 5 above. Note that (4) expresses the frequency of
flows that exceed the fixed average flood stage discharge, although the actual flood stage
discharge may change over time as channel capacity changes. Thus, FF quantifies the flood hazard
frequency, and changes in flood hazard frequency (see below), that would arise in the absence of
trends in channel capacity. Because streamflow can potentially remain above flood stage for
several days within the same event, a flow frequency of several days per year does not necessarily
mean that there were several events in that year. We only calculated flow frequency for calendar
years with nearly complete data (≥ 350 mean daily streamflow values).
B- Trend characterization
We sought to characterize long-term trends in flow frequency using a simple curve with few
parameters. Linear trends are not suitable for this purpose because they can predict negative flow
frequency values, which are physically impossible. Instead we fitted exponential trends to the flow
frequency time series (on linear axes, in order to preserve values of FF=0), as shown in Fig. S6. To
eliminate one fitting coefficient, but still guarantee that the mean flow frequency in the fitted
curve would equal the mean observed FF, we fitted the following unbiased-mean exponential
curve to the flow frequency time series using nonlinear least squares:
FF
exp(r Δt )
=
mean( FF ) mean(exp( r Δt ))
(5)
where mean(FF) is the mean of the observed annual flood stage flow frequencies, r is the fractional
change in flow frequency per unit of time, and Δt = date–mean(date). If Δt is expressed in decades,
then 100 times the coefficient r yields the rate of change in flood-stage flow frequency in percent
per decade, as reported in Fig. 2 of the main paper.

daily discharge equaling or exceeding the long-term average QFS each year).
The grey exponential curve represents the mean-unbiased exponential trend in
annual flood stage flow frequency. This site has a mean flood stage flow
frequency of 12 days per year, and a trend in flood stage flow frequency of 45%
per decade.
C- Trend significance
We used a Monte Carlo permutation method to assess the significance of these trends,
because permutation tests require no distributional assumptions and the flow frequency
distributions are sometimes strongly skewed. Using the annual flow frequency values obtained in
section 6A, we generated 10,000 sample time series by randomly re-ordering the flow frequency
values, and calculated the trend parameter r using equation (5) for each re-sampled time series.
We estimated the statistical significance of the real-world r value from the fraction of permutation
trials that gave equal or greater absolute values of r. This permutation test assumes that there is
negligible serial correlation in the flow frequency time series. The lag-1 serial correlation in the
residuals from the fitted flow frequency trends averaged −0.013 (median value) across our 401
sites, demonstrating that this assumption is reasonable for these data.
7. Effects of channel capacity trends on flood hazard ("channel capacity effects"), estimated
from manual field measurements and mean daily streamflow data
Changes in channel capacity can also affect flood hazard frequency, independently from any
shifts in flow frequency. In this section, we quantify the "channel capacity effect" as the trend in
flood hazard frequency that would arise from measured shifts in channel capacity at flood stage, if
the flow frequency distribution were held constant.
A- Estimated values of flow at flood stage (Fig. S7)
We evaluate the channel capacity effect on flood hazard frequency at the same flood hazard
threshold as the flow frequency effect, namely the defined flood stage (G=FS). However, since
manual field measurements of cross-sectional discharge are rarely made exactly at flood stage, we
need to estimate what Q would have been at flood stage, at the time when each manual field
13/235
measurement was made. As explained by Helsel and Hirsch [1993], in cases where several variables
(e.g., time and G) may affect the magnitude of a response variable (here, Q), the effects of the
extraneous explanatory variable (G) may be removed by fitting a smooth curve to its relationship
with the response variable (here, a curve relating Q to G) and using the residuals from this curve in
subsequent analyses. This procedure corrects for changes in G without assuming that the
relationship between G and Q has any particular functional form.
To remove the effect of differences in gauge height on the relationship between the
manually measured Q and time, we used the Loess curve (Fig. S7) relating the natural logarithms of
Q to G, computed in section 5. We computed the residuals of each Loess curve as:
( )
ln Qˆεi = ln ( Qi ) − ln ( Qi )
(6)
( )
where ln ( Qi ) are the natural logarithms of the observed values of Q, and ln Qi are the natural
logarithms of the estimated values from the Loess curve, obtained using the predict.loess function
from the R statistical programming language [Ripley, 2014], as explained in section 5. Assuming
that the Loess curve represents the time-averaged values of ln(Q) for each value of ln(G), the values
of the residuals (positive or negative) indicate whether each measurement of ln(Q) is less than or
greater than the fitted value of ln(Q) for that value of ln(G). We can then infer that the residuals are
representative of the temporal changes in ln(QFS), under the premise that the temporal trend of
residuals at flood stage is the same as that of residuals over the rest of the curve as a whole. For
example, if early values of Q tend to lie above the line (positive residuals) and later values of Q tend
to lie below the line (negative residuals), it is reasonable to infer a temporal trend toward lower
discharges at any given gauge height, including flood stage (i.e., a decrease in channel capacity).

Figure S7. Estimating values of cross-sectional discharge at flood stage, ln( Q̂ ),
at Big Sioux River near Brookings, SD (section 7A). Dark grey circles represent
manual field measurements of cross-sectional discharge that were retained
following filtering steps (as indicated in Figs S3-S4). The grey curve represents
the Loess fit to the measurements. Vertical grey lines represent residuals from
the Loess rating curve, which indicate how each measurement of ln(Discharge)
deviates from the average value of ln(Discharge) for the corresponding value of
ln(Gauge height). The interpolated value of QFS is indicated by the thin dashed
grey line. Assuming that the residuals are representative of the temporal
changes in ln(QFS), we calculate the estimated values of cross-sectional
discharge at flood stage at each point in time, ln( Q̂ ), as the sum of ln( QFS ) and
the residual ln Qˆεi .
( )

We obtain the estimated values of flow at flood stage as:
( )
( )
ln Qˆ = ln ( QFS ) + ln Qˆεi
( )
(7)
where ln Qˆεi are the residuals of the Loess curve relating ln(Q) to ln(G). QFS was computed in
section 5. The resulting ln Q̂ values are the logarithms of the estimated discharge that would be
required, at the time of each manual field measurement, to reach flood stage (Fig. S7).

B- Quantifying channel capacity effects on flood hazard frequency (Fig. S8)
To estimate how changes in channel capacity affect flood hazard frequency, we estimated
how frequently each value of Q̂ would be attained, given the probability distribution of daily
streamflow values for each site. To do this, we first computed the exceedance curve relating the
exceedance frequency F to Q, as:
Fi = 365.25 ∗
rank (Q )i
(n + 1)
(8)
where rank(Q)i is the rank of each mean daily streamflow value, in descending order, so that the
largest flow has the smallest rank, and n is the total number of mean daily streamflow values
between 1 January 1950 and 30 June 2013. Multiplying by 365.25 annualizes the flood frequency,
to obtain the exceedance frequency in days per year.

Figure S8. Exceedance curve relating ln(Exceedance frequency) to ln(Discharge)
at Big Sioux River near Brookings, SD. Exceedance frequencies of historical mean
daily streamflow values are indicated as open grey circles. The thin black line
indicates Loess fit to these exceedance frequencies. Extracted exceedance
frequencies for estimated Q values are indicated as filled, dark grey circles:
these are the exceedance frequencies used to compute the trend in flood
hazard attributable to changes in channel capacity (Fig. S9).
For each site, we plotted the exceedance curve for mean daily streamflow values, using loglog axes so that the distribution would not be sharply curved (Fig. S8). To smooth any variability in
the exceedance curves, we fit a Loess curve (as explained in section 5) to the mean daily
15/235
streamflow values. We used only mean daily streamflow values within a range of 0.2 log units
above or below the ln ( Qˆ ) values, to ensure a good Loess fit near the ln ( Qˆ ) values (because these
are often located at the tail of the exceedance frequency distribution) (Fig. S8).
We then extracted the exceedance frequencies of each ln ( Qˆ ) from the Loess curve. At 3 sites
(<1% of all sites), a total of 25 Q̂ values (<0.2% of all Q̂ values) were found to exceed the highest
mean daily streamflow values on record, and so could not be interpolated from the Loess curve.
These values were considered unreliable and so were removed from the computation of channel
capacity effects.
C- Quantification of flood hazard frequency trends due to changes in channel capacity (Fig. S9)
In the same way as for flow frequency in section 6, we sought to characterize the long-term
trend in flood hazard frequency due to changes in channel capacity, using a simple curve with few
parameters. However, in contrast with flow frequency, where there is little error in the estimated
flow frequency values (because it is clear whether each streamflow value equals or exceeds QFS ),
we are more likely to find outliers in channel capacity, due to measurement errors or undetected
variations in manual field measurement locations. It is therefore important that we downweight
the influence of any such outliers to limit their influence on the trend estimates. To downweight
the influence of outliers, we computed an iteratively reweighted least squares [IRLS: Holland and
Welsch, 1977] trend in the non-logged frequencies obtained for Q̂ from the exceedance curve for
each site (Fig. S9). IRLS is an iterative procedure that is typically used to mitigate the influence of
outliers in regression models. In our IRLS routine, we used a Cauchy weighting function [Holland
and Welsch, 1977] applied to the residuals from the fitted function, so as to minimize the influence
of outliers, as:
wi =
1
2
ai
1+
3.536 MAR
(9)
where ai is the residual corresponding to an individual point, and MAR is the median absolute
residual. So that the effects of changes in channel capacity and flow frequency are quantitatively
comparable, we used the same exponential unbiased mean form of the least squares trend as for
flow frequency. We fit the trend in the corresponding Fi values as:
Fi
exp( r Δt )
=
wt.mean ( Fi ) wt.mean (exp( r Δt ))
(10)
where wt.mean(Fi) is the weighted mean of the exceedance frequency at flood stage, Q̂ , using the
IRLS weights for each point, r is the fractional change in channel capacity per unit of time, and Δt
= date–mean(date), as before. Figure S9 shows the exponential trend passing through the
exceedance frequencies, after IRLS down-weighting of outliers. We tested for lag-1 serial
correlation in the residuals from the fitted trends, and found a median correlation of 0.13.
Accounting for serial correlation barely modified the significance of the estimated trends (it
increased p-values by +0.0037 on average, for the 401 sites). Thus, we concluded that the raw IRLS
exponential weighted mean model could be used without correcting for serial correlation. The
effects of channel capacity changes on flood hazard are computed in percent per decade (r times
100, with Δt expressed in decades), allowing for a direct comparison between channel capacity
and flow frequency effects (Figs. S6 and S9). This also means that the sum of the channel capacity
16/235
Channel capacity
exceedance frequency (d/y)
and flow frequency effects (both in percent per decade) corresponds to the total change in flood
hazard frequency (in percent per decade) at each site.

Figure S9. Trend in flood frequency due to channel capacity changes, at Big
Sioux River near Brookings, SD. Dark grey circles indicate Q̂ exceedance
frequency values, which were extracted from the exceedance curve (dark grey
circles in Fig. S8). Dark grey curve indicates mean-unbiased exponential IRLS
trend for these exceedance frequencies. Note: the curves are exponential, but
the curvature is indistinct for many sites due to the scatter in the underlying
data. At this site, the Q̂ exceedance frequency values display considerable
variability due to the frequent adjustments of the sand and silt channel
boundaries in this river. The channel capacity effect on the flood hazard
frequency is −16% per decade.
8. Trends in cross-sectional channel area and cross-sectional average flow velocity at flood
stage, using manual field measurements
Channel capacity can be divided into the two components that determine the volume of flow
at flood stage, namely cross-sectional channel area and cross-sectional average flow velocity
(equation (1b)). Our aim is to determine the proportions of changes in channel capacity that result
from shifts in AFS and from shifts in VFS for each site, assuming that the flow frequency distribution
remains constant over time. To do this, we quantify the temporal trend in AFS and VFS in percent per
decade.
A- Estimated values of cross-sectional channel area and cross-sectional average flow velocity
at flood stage
In the same way as described for flow, in section 7A, manual field measurements of A and V are
rarely made exactly at flood stage. However, we estimate trends in A and V at flood stage by
removing the effect of differences in gauge height. To do this, we use the Loess curves relating the
natural logarithms of A and V to G, which were computed in section 5. In the same manner as for Q
in Fig. S7, we compute the residuals to each Loess curve as:
( )
ln (Vˆεi ) = ln (V ) − ln (V )
ln Aˆεi = ln ( Ai ) − ln ( Ai )
i
i
(11a)
(11b)
where ln ( Ai ) and ln (Vi ) are the natural logarithms of the observed manual field measurements,
( ) and ln (V ) are the natural logarithms of the estimated values from the Loess curve,
and ln Ai
i
17/235
obtained using the predict.loess function from the R statistical programming language [Ripley,
2014], as explained in section 5.
Assuming that the Loess curve represents the time-averaged values of ln(A) and ln(V) for each
value of ln(G) (Fig. S5b-c), the values of the residuals (positive or negative) indicate whether each
manual field measurement of ln(A) or ln(V) is less than or greater than the average value of ln(A) or
ln(V) for that value of ln(G), following the same procedure as for Q in Fig. S7. As long as the
temporal trend of residuals at flood stage is the same as that of residuals over the rest of the curve
as a whole, we can then assume that the residuals are representative of the temporal changes in
ln(AFS) or ln(VFS). We obtain the estimated values of ln(A) and ln(V) at flood stage as:
ln Aˆ = ln ( AFS ) + ln Aˆεi
( )
( )
(12a)
ln (Vˆ ) = ln (VFS ) + ln (Vˆεi )
(12b)
( )
( )
where ln Aˆεi are the residuals of the Loess curve relating ln(A) to ln(G), and ln Vˆεi are the
residuals of the Loess curve relating ln(V) to ln(G). AFS and VFS were obtained in section 5. The
( )
( )
resulting ln  and ln Vˆ values are the estimates of ln(A) and ln(V) that that would be required,
at the time of each manual field measurement, to reach flood stage.
B- Trend characterization
We can compute the time trends in  and V̂ using a similar curve as for the channel capacity
trend in section 7C:
Aˆ
exp(rΔt )
=
mean( Aˆ ) mean(exp(r Δt ))
(13a)
exp(rΔt )
Vˆ
=
mean(Vˆ ) mean(exp( r Δt ))
(13b)
where mean( Â ) and mean( V̂ ) are the means of the estimates of A and V at flood stage; r is the
fractional change in  or V̂ per unit time; and Δt = date–mean(date).
