This research project focused on improving several aspects of the Flood Estimation Handbook (FEH).
This project has updated most technical details of the FEH method to improve the performance procedures. These improved procedures will enable more accurate flood frequency estimation. The updates are required in part because of the availability of a much-improved database of flood data.
The key improvements are:
- a new regression model for estimating the median annual maximum flood (QMED) at ungauged catchments
- an improved procedure for the use of donor catchments for estimation of QMED at ungauged catchments
- an improved procedure for formation of pooling groups and estimation of pooled growth curves
This report describes the studies that have led to the new recommendations.
The project ran from 2005 to 2008.
