Why this Catchment?

The micro-catchment was selected in the GIS modelling step because it contains a large number of properties in Walkhamptonthat are

potentially at flood risk. The map below shows which buildings overlap with the EA’s modelled “Flood Zone 2” area, specifically areas at risk of flooding from rivers, as identified during the micro-catchment mapping process.

There are 11 buildings potentially at risk out of 58 in the catchment, approximately 18.97% of them. The catchment’s size of 2.26km2 gives an area of 0.21km2 per building at risk.

The water framework directive (WFD) status in the wider River Walkham catchment is Moderate for ecological, and Failing for chemical

If property owners are willing to work with landowners and vice versa, then small-scale NFM measures upstream in the catchment have the potential to benefit a large number of properties and improve water quality.
