BEST PRACTICE GUIDE
VERSION # 1 – APRIL 2013
RIVER EROSION REPAIR
Details contained in this document have been
prepared to offer assistance to GWRC staff and
Contractors.
The techniques and plans contained in this Guide
have been prepared and included on the basis of
the information accumulated by GWRC and the
experience of GWRC staff over many years in
undertaking and supervising repair work. This is
made available to offer assistance to rural
landowners who experience erosion and are
considering whether or not to undertake repairs.
The guidelines and plans have been compiled to
deal with common or standard situations.
Landowners are cautioned against using the
guidelines and plans in circumstances which may
not be common or standard and are advised to
seek professional assistance if in doubt or where
there has been significant erosion. While GWRC
has endeavoured to ensure the guidelines and
plans are a fair statement of the best practice
derived from experience, it cannot assume
responsibility to any third party for the reliability,
accuracy or completeness of the information or
plans contained in this Guide or of the
applicability of either to any particular
circumstances.
In areas of significant erosion, detailed
engineering investigation / design may be
required.

plan assume no responsibility as to the reliability, accuracy or
completeness of the information shown or for any interpretation
or action taken by any agency or individual in relation to
information provided on this plan.
2. Groyne spacing is a judgment call depending on factors such as tightness of the
bend, stream gradient and bank material etc. A general rule of thumb is : Groyne
spacing = 1.5 x the distance between erosion face and preferred channel
alignment.
This plan has been prepared to offer assistance to rural
landowners, the landowner is under no obligation to carry out
these works. In areas of significant erosion, detailed engineering
design / investigation may be required.
Typical groyne spacings that have been used are :
Hutt River: Nash Street 60m crs
: Belmont 70m crs
: Bridge road 50m crs
: Ava - Ewen 78m crs
Waikanae River : 45 - 70m crs (generally on bends)

NOTES:
GENERAL
This plan has been prepared to offer assistance to rural
landowners, the landowner is under no obligation to carry out
these works. In areas of significant erosion, detailed engineering
design / investigation may be required.
•
All dimensions in millimeters unless noted otherwise
RAILWAY IRONS
The landowner will need to contact the necessary authorities and
service providers for building consent/resource consent (if
applicable) prior to any work being carried out. Please note there
is always a risk of works being outflanked or destroyed in a flood.
See also caution on cover sheet.
•
All railway irons to be in good condition and without significant corrosion
•
Railway irons to be founded with no more than 200mm cut off for driving head
damage
•
All railway irons to be driven within 100mm of location shown on the drawing and
shall be within a vertical tolerance of 1:50
•
Top of the Railway irons to be uniform grade between set out levels
CABLES
•
Cables shall be 14mm or 12mm 0 galvanised wire rope
•
The three longitudinal cables shall be passed through holes in the web of each iron
and tied off at every 50m as shown in the details RL-5317 / 27
•
Diagonal cables shall be placed every 3m (at the same location as mesh
diaphragms).
•
All cable tie-offs shall be made using two galvanised steel wire grips.
•
Cables shall be tensioned and tied off such that all kinks or curvature in the wires
are straightened out and so that they do not deflect under moderate hand pressure
between points of support
MESH and LACING WIRE
•
All mesh to be used shall be 75mm mesh size, 2.5mm galvanised wire core,
3.6mm of green plastic coated chain-link.
•
The end of roll of chain-link mesh is to have the end wire removed and knitted into
the next so that it forms a continuous length.
•
All lacing wire shall be 2.2mm galvanised wire core, 3.2mm of green plastic coated
wire.
•
Ends of all lacing to be tied off around a railway iron or cable (no intermediate
joins), use fencing knots.
•
Front mesh to be tied to the longitudinal cables using double loop lacing through
every netting link.
•
Front mesh and diaphragms to be tied to every third rail iron (at same location as
diagonal cables) using single loop lacing through alternate netting links.
•
Top mesh to be tied to the longitudinal cables and top of each diaphragm using
single loop lacing
WILLOW POLES
•
2.5m - 3.0m Matsudana willow poles are to be tied to the top longitudinal cable at the
rear of the gabion basket at 1.5m centres using biodegradable string prior to back
filling.
•
Poles are to be founded so the base is embedded at least 0.5m below water.
SHADE CLOTH

•
Shade cloth to be used is super hailtex.
•
Cloth is to be laid length-wise along the works with 0.5m of the end of each 6.5m
wide roll fixed as shown in the diagram. The end of each roll is to be overlapped on
on top of the downstream roll by at least lm.
•
Each roll of shade cloth shall be pinned down along the the centre of the roll using
strained fencing wire pinned down at 30m intervals using 750mm long pins formed
from D16 reinforcing steel as detailed on drawing RL-5317 / 20.
