HISTORY
Place nam es such as O rd n an ce
Place, C inderhill, Pow derm ill
and th e various Forges preserve
th e m em ory o f the iron w orking
activities in the area. T here
w e re for exam p le, no less than
te n iro n w orkin g sites w ithin
th ree m iles o f Mayfield Church.
T he o re w as first ex p lo ited in
th e Iron Age, and th en by the
R om ans
and
sporadically
th ro u g h th e M iddle Ages. The
h e ad w a ters w ere used for
c o o lin g th e m olten masses of
iron w h ich w ere e x tra c te d by
h eatin g w ithin a charcoal
m ound. By T u d o r tim es, blast
furn aces revolutionised th e
industry. The d raught from
b ello w s cre a ted h igher te m p ­
e ra tu re s allow ing cast iron to
b e p ro d u c e d and w rought. The
ste e p stream s w e re ideal for
d am m in g to give a head of
w a te r to drive w a ter w heels
for b ello w s and forging h am ­
m ers. At that tim e, m ore than
half th e iron-mills o f the country
w e re situ ated in th e Weald.
T he history o f th e low er
re a c h e s o f the river and o f th e
R om ney M arshes is alm ost lost
in th e m ists of tim e. Longshore
Drift, th e p ro cess by w hich
shingle is driven from W est to
East by w aves in d u ced by the
prevailing south w esterly winds,
has b e e n the m ajor force in
shaping th e riv er outfalls and
th e associated marshlands.
It is p ro b ab le that in late
p re h isto ric tim es, a long and
continuous shingle ridge stretch­
ed m ost o f th e way across
th e shallow bay b e tw een Fairlight and Sandgate. Behind this
lay a large lagoon into w hich
th e Rivers B rede, Tillingham
and R other flowed. T he main
o u tle ts for th e R other w ere
fu rth e r East, b e tw een Lydd and
R om ney n ear th e p resen t site
o f W est Hvthe. Siltation in th e
lagoon
eventually
allow ed
m arshlands to be reclaim ed o r
“in n e d ” and in th e p ro cess
cau sed th e outfall to m ove
w estw ard tw ice.
M an’s c o n tin u in g
efforts
d rain ed th e land and m ade it
habitable and agriculturally
profitable. Today som e 27,000
ha o f wonderfully fertile land lie
betw een th e old sea cliffs and
th e coastline. Altogether, m ore
than tw o thirds rem ains below
th e level o f high tides, d ep en d ­
ing on flood defences and land
drainage for its preservation
and productivity.
In early Roman times th e
river w as known as th e Limene
and entered th e sea near
Hythe. A Roman fort, th e
rem ains of which are easily
seen, was built near the present
l.ympne Castle site to p ro tect
th e harbour, Portus Lemanis.
By Mediaeval tim es the u n ­
relenting shingle drift and silta­
tion w ithin th e lagoon had
caused the river m outh to move
back to Romney, w hich w ith
Hythe, Hastings, Dover and
Sandwich was o n e of th e
C inque Ports. This in turn
set up the form ation o f the
shingle prom ontory known as
Dungeness.
A succession o f storm s and
floods savaged north-w estern
Europe during th e thirteenth
century. A great storm in 1287
caused the river to forsake its
old channel to take a shorter,
m ore westerly ro u te to th e sea
by Rye. A ccretion of shingle
seaw ards at a rate of several
m etres a year, has resulted in
th e river n o w discharging
som e 4 km from th e town.
Through th e centuries p ro ­
gressive reclam ation o f land
and the construction of sluices
greatly reduced the am ount of
tidal water eb b in g and flowing
through the estuary. This en­
couraged siltation in the
harbour and th e form ation of a
shingle bar across th e river
m outh. In this co n tex t the
needs of seafarers and land­
ow ners have inevitably been in
conflict and have still to be re­
solved by com prom ise.
GEOLOGY AND
HYDROLOGY
In the heart o f the W eald the
Wadhurst ('.lay is som e 45m
thick and separates th e Ash­
down and Tunbridge Wells
Sands. Being im perm eable to
rainfall, th e clay dictates the
flashy ch aracter of th e head­
waters. In w in ter they respond
quickly to rainfall, but in
summer they lack strong
springs su ch as th o se issuing
from chalk areas elsewrhere in
the region.
Some w'ater supplies in the
area are taken from u nder­
ground and the principal w ater
bearing rocks are the sand­
stones,
particularly
the
Ashdown Sands.
However,
most o f the w ater needed for
public supply is taken from
rivers and reservoirs.
W ater is pum ped from the
river at Robertsbridge to
Darwell Reservoir som e 3 km
away. The reservoir is operated
by Southern W ater Services Ltd
w hich uses it for direct supply.
C o nstructed in 1950, it has a
maxim um storage capacity of
4460 Ml and a design yield of
21.9
Ml/d. The
reservoir
occu p ies 69 ha but is currently
being enlarged. Powdermill
Reservoir, located on the River
Brede, is a small im pounding
reservoir used for direct supply.
W ith a surface area of 21 ha, it
has a storage capacity of 808
Ml. Southern W ater Services
Ltd also abstracts underground
wraters from the Brede Wells
to its Brede W ater Treatm ent
Works.
River flows are m easured by
a gauging w eir at Udiam and by
an ultrasonic flow gauge at
Blackwall Bridge near W ittersham. T here are flow gauging
stations on the River Dudwell,
th e River Brede and the
H exden Channel.
T here are a large num ber of
m inor abstractions for agricul­
tural purposes in the catch ­
m ent, particularly for spray
irrigation on the Romney
Marshes and in the Shirley Moor
area. High value agricultural
cro p s such as potatoes, depend
to a large degree upon the
availability o f this w ater. The
National
Rivers
Authority
o perates and enforces an
abstraction licensing system
w hich ensures that w ater is
taken at th e right tim es and
only from the places w h ere it
can most be spared.
South o f the Marshes lies the
shingle prom ontory o f D unge­
ness. This is an area o f unique
im portance for a w ide range of
bird life and also an im portant
source o f w ater for th e Folke­
stone and D istrict W ater
Company. larg e volum es of
fresh w ater are taken daily from
beneath th e shingle for public
supply. Gravel extraction for
the construction industry' in­
volves th e NRA in considerable
investigatory w ork to ensure
the integrity of th e w ater
supplies in the shingle and to
safeguard them from saline
intrusion.

radically ch anged at a stro k e
by th e b uilding o f th e Royal

W ater from the Marsh was lifted
in to th e Canal, first by w in d ­
mills and then by steam pum ps.
T oday th e M arsh is still drained
to th e Canal by p u m p in g sta­

statio n at U nion Sluice drains
th e W alland Marsh to th e tidal

drain small areas o f m arsh
d irectly to th e sea.
T he Royal Military Canal —

thing o f great beauty - also
serves as a reservoir d u rin g th e

Along th e coast, the shingle
