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.[4]
Development History
Initially developed by Halcrow Group and then CH2M Hill, Flood Modeller is now developed by Jacobs Solutions. Flood Modeller was previously known as "ISIS" (after the local name for the Upper Thames).
Solvers
1D solvers
Flood Modeller includes steady-state and unsteady 1D river solvers for modelling open-channels.
It also provides a 1D urban solver for modelling urban drainage systems.
2D solvers
Flood Modeller includes three different 2D solvers:
- The ADI solver is based on the DIVAST numerical engine first developed in the 1980s, and is designed to simulate fluvial, overland, estuarine and coastal situations where flow does not rapidly change.[5]
- The TVD solver is designed to represent rapid changes in the water surface profile, but results in longer run-times.
- The FAST solver uses simplified hydraulics to perform rapid assessments of flooding.[6][7]
