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 Array.

At the time of recording the flow of water was Array and the channel was Array wide and Array in depth.

For most of this stretch the channel profile is shallow.

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


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

Field drains were recorded as Array and barriers / culverts are Array.


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


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

Additional Information
