ReFH 2ReFH 2 enables you to estimate design and observed flood hydrographs for rural and urbanised ungauged catchments across the UK. Using ReFH 2 in conjunction with the FEH Web Service, you can estimate runoff rates and volumes for specific development sites.

ReFH 2 is the latest version of the Revitalised Flood Hydrograph (ReFH) model. The model draws on the FEH22 and FEH13 rainfall model data available from the FEH Web Service. For further information on the methods, see our openly published online technical guide and supporting science reports here:

ReFH 2 has been integrated with the latest version of InfoDrainage, Flood Modeller,  InfoWorks ICM, Flow and TUFLOW.

ReFH2 is available on an annual subscription, activated online with a serial number. It can be licensed either for standalone/single PC use, or as a multi user/network licence through our reseller Jacobs. See Licensing for details.
