The Flood Estimation Handbook (FEH) gives guidance on rainfall and river flood frequency estimation in the UK. Catchment descriptors for ungauged sites are supplied on the CD-ROM. Data is available for all sites on drainage paths in mainland Britain, Northern Ireland, the Isle of Wight and Anglesey, which have a catchment area of at least 0.5 km2. The CD-ROM also holds catchment average values of the six rainfall depth-duration-frequency model parameters (FEH Volume 2) for the same locations.

A new lumped conceptual rainfall-runoff model, the Revitalised Flood Hydrograph (ReFH) model has been developed for modelling flood events. The ReFH model is based on robust hydrological modelling techniques and is considered to be an improvement over the existing FSR/FEH model. It enables a more direct and transparent description of flood-generating mechanisms and introduces the concept of seasonal variation in soil moisture content, design rainfall and baseflow.

River Flow Forecasting System. Produces forecasts of river level and flow in real-time from telemetered data. The suite of models includes PDM rainfall-runoff model and KW channel flow routing model.

Quantifying uncertainty in the assessment of the Water Framework Directive (WFD) ecological status class of rivers, lakes and other water bodies based on Ecological Quality Ratios (EQRs) of biological metrics or indices (benthic invertebrates, phytoplankton, macropytes and phytobenthos, fish and/or habitats).
