River Roach

The brook travels through the urban area of Prittlewell. The channel is mainly concrete lined with little inchannel vegetation, however this changes downstream where the channel begins to become choked with vegetation. 

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 unknown, and riffles are present in the downstream section only.

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

For most of this stretch the channel profile is steep and concrete lined.

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


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.


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


Species seen during the survey: Magpie, Robin, Tortoiseshell butterfly, Feral Pigeon, House Sparrow, Mallard and Blackbird.

Additional Information

There was a problem with algae at the time of the survey, this could indicate that there is a problem wiith misconnections and general urban drainage in the immediate area increasing the nutrient levels of the water.

Sewage fungus and ochre were seen in places throughout this stretch and fly-tipping was also an issue.
