All four editions of Flood Modeller offer integrated catchment modelling capabilities allowing you to confidently model rivers, sewers, overland flows and rainfall-runoff.

Flood Modeller is available on a monthly, annual or lifetime basis allowing you to develop in-house modelling capabilities or deliver a one-off project in a cost-effective way.

We offer standalone and networked licences which makes Flood Modeller perfect for single users or larger organisations with multiple offices and users.

Jacobs and Wallingford HydroSolutions Ltd have formed a strategic collaboration targeting data and technology solutions for hydrological and hydraulic modelling servicing the flood risk and climate resilience markets.

Jacobs is the exclusive reseller of Wallingford HydroSolutions' WINFAP and ReFH2 cloud and network licences. Our annual subscriptions allow anybody to access the hydrological software when they're not in use, on any machine, as long as they have access to the company network (including via VPN to promote hybrid working). Your licences are no longer tied into a machine, meaning you can work more quickly and efficiently with direct access to the tools you need. 


£790 /year

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.


£590 /year

ReFH 2 enables you to estimate design and observed flood hydrographs for rural and urbanised ungauged catchments across the UK.
