Client: Environment Agency
In 2010, the Environment Agency produced Reservoir Flood Maps (RFM) for large raised reservoirs at a national scale across England and Wales. Those maps are used to inform a range of applications including emergency planning, reservoir risk designation, spatial planning and community awareness. BMT with partners JBA and Mott McDonald are delivering a major update of these maps using latest advances and innovations in software and hardware to reflect technical advances in dam break analysis, hydrology, computational hydraulic flood modelling and digital terrain models.
Outcomes and Benefits
The primary users of the Reservoir Flood Maps are Local Resilience Forums (LRFs). LRFs use these maps for emergency planning to prevent or mitigate impact on local communities. Outputs will also be used by reservoir owners, panel engineers, spatial planners and the community to assess the possible consequences of dam failure. To produce high resolution, national-scale maps as efficiently as possible, the project team harnessed the benefits of a secure, cloud-based solution together with bespoke coding to maximise automation of workflows.
Services and Expertise Provided:
The Brisbane River Catchment Flood Study is the most detailed and comprehensive flood study ever undertaken in Australia. The hydraulic models that were developed underwent rigorous calibration. A sophisticated Monte Carlo approach was used to hydraulically model 11,340 flooding scenarios. The result was a robust and defendable set of design events. The study was fully peer reviewed by a panel of independent experts.
BMT was appointed to review the methodology and modelling to inform a Flood Risk Assessment in Essex. Following the review recommendations for any limitations of the Flood risk Assessment have been sent to the client in a technical note.
Surface water flood modelling study to determine baseline flood risk through a rural village which is located downstream of a proposed Power Company development site. The project determined the existing flood risk to inform the planning and DCO submission from the power company for a new windfarm substation connection for offshore turbines to the National Grid.
A comprehensive study of the flood behaviour and flood risk of the Swan and Helena Rivers and preparation of a floodplain development strategy.
