Flood estimation handbook

An Environment Agency-funded project to update the FEH statistical flood frequency procedures has built on theoretical developments together with the availability of flood peak data from HiFlows-UK, resulting in substantial improvements to the predictive capability of the method. Please visit our FAQs page for further information on this. Other related aspects of the FEH are also being explored, for example the development of new flood risk maps based on the revised methods together with high resolution digital terrain models.

While some key improvements have been made to the existing methods, a number of challenges remain, particularly to improve flood estimation in urban areas and in permeable catchments. The Estomation Estimation Handbook comes with two associated pieces of software: Flood frequency estimates are required for the planning and assessment of flood defences, and the design of other structures such as bridges, culverts, and reservoir spillways.

To become an organisational user, either your organisation will already have an organisational account set up or a lead user will need to be nominated to arrange for set up.

The procedures are clearly explained, and supporting theory and results included. Finally, the rainfall-runoff method, which was originally developed as part estimarion the Flood Studies Report, has been replaced by the ReFH model for design hydrograph analysis. Downloads per month over past year.

Moreover, it handbooi becoming increasingly urgent to consider the likely impacts of climate change on flood and rainfall frequency in the UK and to develop new methods for frequency estimation in a non-stationary environment.

It also provides the descriptors and rainfall DDF estimates for any location to support the derivation of runoff rates and volumes to support drainage design using the FEH rainfall runoff methods ReFH 2.

It provides catchment level descriptors and rainfall depth-duration-frequency DDF estimates to enable flood risk to be estimated for over four million catchments across the UK.

The major benefits of the FEH have been seen in improved risk management and policy implementation, and have had a considerable impact on the UK economy. There is an increasing demand for estimates that can form the base for flood risk maps, important in the estimtaion of new developments.

This paper considers each of the three key components of the FEH, the rainfall frequency model, the statistical approach to flood frequency estimation and the rainfall-runoff method, and describes how recent and ongoing research is leading to methodological improvements. The FEH Web Service provides the data and rainfall model outputs that are required to apply the UK flood frequency and rainfall estimation procedures.

The FEH, which encompasses a suite of methods for statistical frequency analysis of rainfall and floods, was innovative both in its use of digital catchment information and in the way that data from a number of sites can be pooled together to improve the quality of estimates at gauged and ungauged sites.

An important aspect of the development of FEH methods is putting the estlmation into practice and the paper highlights how this is being managed through the development of new FEH software products, as well as allowing the algorithms to be implemented within other widely used packages.
