River Roach

This section is canalised with concrete reinforced banks for the whole stretch. Vegetation is limited in this area and the overland runoff is a possible issue. There are man-made barriers present including a weir and a culvert.

The area (land use)

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

No livestock were recorded.

Channel characteristics

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

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

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

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


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

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


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


None seen during the survey.

Additional Information

This section of the brook has garden fencing near ro the bank and some residents are disposing of garden cuttings over the fence. This could be an issue for the brook as it may be introducing invasive plants to the banks and any chemicals used in the garden (including fertilisers) can enter the channel and impact on the water environment and water quality. The channel is very shaded by surrounding trees.

At the end of this stretch the banks become heavily reinforced and a flow deflector/weir is present (see photo). Some type of monitoring station is present at this point.
