Essex Rivers Hub

The channel is canalised and reinforced with scrub along both banks after the sluice gate. Due to the dense scrub the channel and bank are very shaded, which is probably one of the factors that is preventing the growth of in channel vegetation. The channel is straight and generally featureless and there is little connection between bankside and in channel habitats due to the reinforcement along most of the stretch.

The area (land use)

The dominant land use for this stretch of river is suburban/urban.

No livestock were recorded.

Channel characteristics

The river channel consists of mainly silt, and riffles are absent.

At the time of recording the flow of water was sluggish and the channel was 5-10m wide and 1-2m in depth.

For most of this stretch the channel profile is shallow.

Bankside trees were abundant, marginal plants and in-channel plants are abundant. Woody debris was noted to be rare.

Engineering

The channel has been straightened and man-made enhancements are present along this stretch of river.

Field drains were recorded as absent and barriers / culverts are present.

Condition

Areas of trampling / poaching were absent and areas of erosion were absent at the time of the survey.

Wildlife

A kestrel and magpies were seen at the time of the survey.

Additional Information

Banks are more natural where they are close to the Thames and Rainham Marshes.

Fly tipping is an issue as shopping trolleys, push bikes, motor cycles, tyres and electrical goods were found in the channel.
