There is a product website for Flood Modeller which is more relevant and is kept up to date }} Flood Modeller is a computer program developed by Jacobs that assesses flood risk by simulating the flow of water through river channels, urban drainage networks and across floodplains using a range of one- and two-dimensional hydraulic solvers.
The software incorporates a user interface for building, running and viewing the results of models, including a GIS map interface.
The software has been independently benchmarked[1] by the Environment Agency and is used extensively[2] to undertake modelling of flood risk,[3] develop flood risk management schemes and provide flood forecasting services.
Flood Modeller was previously known as "ISIS" (after the local name for the Upper Thames).
