Flood models are required to determine the risk of flooding to a site when an initial desktop review has shown the site may be located within a floodplain.
When Are Flood Models Required?
Flood models are required to determine the risk of flooding to a site when an initial desktop review has shown the site may be located within a floodplain. This may be due to:
- The site being located within Flood Zone 2 or Flood Zone 3
- A watercourse within close proximity of the site
- The site shown as being at risk from surface water flooding.
Detailed modelling is often needed for detailed planning applications where national scale mapping is either not available, or not fit for purpose.
Flood modelling can bridge the gap to ensure your planning application has the most accurate data to gain approval. Aegaea are experts in integrated catchment modelling, fluvial flooding, hydrology and flood risk and can advise on flood modelling anywhere in the UK and internationally.
Does a flood model of this watercourse already exist?
The answer may well be yes. If your site is located in an urban area or by a significant watercourse, the Environment Agency may already hold a hydraulic model that can be utilised to inform a site-specific assessment of risk. Aegaea will submit a request to the Environment Agency, obtain a copy of this model for you (if available) and review it to ensure it is suitable for use in a Flood Risk Assessment and identify any areas of improvement required to ensure a smooth journey through planning.
