Flood Risk Assessment including 1D-2D hydraulic modelling, Denny, Scotland
Jan 12, 2017

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 Denny, Scotland.

The main source of flooding was from a small watercourse that flows through the development site. There was no modelled data for this small watercourse and consequently a hydraulic model was developed using Flood Modeller Pro. The model included a complex arrangement of single culverts, and spills.

In order to meet the requirements of the Scottish Planning Policy (SPP), our assessment involved:

  • Data collection, including hydraulic modelling of the small watercourse.
  • Liaison with the Scottish Environment Protection 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.
