Flood Risk Assessment including 1D-2D hydraulic modelling, Walsall, West Midlands
Oct 24, 2016

Flood Risk Assessment including 1D-2D hydraulic modelling has been completed by RAB Consultants in support of a planning application for a residential development in Walsall, West Midlands.

The site was in flood zone 3 in accordance with the Environment Agency’s flood map. The main source of flooding was Waddens Brook, which runs to the south of the site. There was no modelled data for Waddens Brook and consequently a hydraulic model was developed using Flood Modeller Pro. The model included a complex arrangement of bridges, single culverts, double culverts and spills. Flood risk was mapped using 1D-2D linked schematization.

Our assessment in order to meet the requirements of the National Planning Policy Framework (NPPF) involved:

  • Data collection, including hydraulic modelling of Waddens Brook.

  • Liaison with the Environment Agency

  • An assessment of the risk of flooding from all sources including fluvial, groundwater and surface water.

  • Recommendations were provided, balanced against design / construction constraints specified by the client.
