Details

Without substantially changing the overall framework of the existing FEH methodology, this project has updated most technical details of the FEH method to improve the performance of the procedure. The updates include significant improvements to the theoretical statistical framework underlying the method. 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
