GovWire

These standards are techniques that you can use in the fields of hydrological analysis and hydraulic modelling. Use this best practice guidance to help you:

• build hydraulic models using the source, pathway, receptor and model approach concept
• review hydraulic models
• maintain consistency across the flood risk management industry
• improve the quality of your applications
• plan and prioritise targeted model updates

Technical standards

These standards are also available as a PDF (LIT56326) that gives more background information for hydraulic modelling and uses technical and scientific language.

Email enquiries@environment-agency.gov.uk to request a copy of the PDF.

Fluvial model assessment tool

You can use the Microsoft Excel-based fluvial model assessment tool (LIT56342) alongside these standards. The tool will help you assess the quality of a hydraulic model without completing a full technical review.

Email enquiries@environment-agency.gov.uk to request a copy of the tool.
