The Roding is a small, lowland clay river which drains a narrow catchment (342km2) in Western Essex. Rising at Molehill Green, 107m above sea-level, it flows in a southerly direction for 80km, joining the Thames at Barking Creek. During dry weather, the flow measured at Redbridge gauging station is usually less than one cubic metre per second but increases rapidly after heavy rainfall. In the middle reaches, near Abridge, the channel gradient is gentle (1:100) and the river comprises alternating shallows (riffles) and deep water pools. The average channel width is 7.5m and the river bed comprises mainly clay or gravel, but extensive silt deposits occur in sheltered bends. There has been considerable channel realignment and bank reinforcement associated with flood alleviation and motorway construction in the lowest reaches where the catchment is heavily urbanised. In contrast, agriculture dominates the upper and middle catchment. The average annual rainfall in the Roding catchment is 606mm.
