WINFAP 5 enables you to estimate peak flows and flood frequency curves for gauged and ungauged catchments, using the latest Flood Estimation Handbook (FEH) methods.
At an ungauged site you can automatically create a pooling group of similar gauged sites based on comparison of FEH Web Service catchment descriptors.
At a gauged site you can apply flood frequency analysis techniques to gauged annual maximum and/or peaks-over-threshold flood peak data where available. Flood frequency curves are created by analysis of the pooling group flood peak data.
WINFAP 5 was developed by WHS to implement a range of the industry-standard FEH statistical analysis tools. It uses the latest FEH methods to provide estimates of peak flows and flood frequency curves for gauged and ungauged catchments.
WINFAP is available on an annual subscription, activated online with a serial number. See Licensing for details.
WINFAP 5 uses the new NRFA Peak Flow catchment descriptor xml files, therefore WINFAP 4 can be installed alongside WINFAP 5 to enable continued use of old Peak Flow Datasets (version 9 and earlier) on existing projects. Both WINFAP 5 and WINFAP 4 serial numbers are currently provided.
