Rainfall Runoff Modelling using ReFH

1.00 day


The Revitalised Flood Hydrograph Method (ReFH) is a technique for estimating design hydrographs, designed to overcome many of the problems and limitations of the FEH rainfall-runoff method.  It has superseded the FEH rainfall-runoff method for most applications in England, Wales and Northern Ireland.   The course covers ReFH in detail.

Who should attend

The course is designed for those who already have some understanding of FEH methods (for example, through attending a Flood Estimation Handbook course) and would like to update their knowledge to the latest methods and guidance.

Course outcomes

Delegates will have a more detailed understanding of the theory behind ReFH and the ReFH Design Flood Modelling Software.

Topics covered

  • Reasons for the development of ReFH
  • Theory of the ReFH model
  • Application of ReFH for estimating design events
  • Simulation of observed events
  • Estimating model parameters from catchment descriptors and flood event data
  • Cautionary notes and situations where ReFH performs poorly
  • Using the ReFH software (both the spreadsheet and the full software package)
  • Choice between ReFH and alternative methods
  • Comparison of results from ReFH and other methods
