Our verdict on Flood Modeller
Flood Modeller is hydraulic and hydrological modelling software from Jacobs for professionals assessing flood risk and planning infrastructure. It is suited to teams working on river flooding, urban drainage, surface-water flows, infrastructure design or flood forecasting. Models can represent 1D river and drainage systems, 2D flood flows, or linked 1D and 2D components with dynamic exchange. Hydrological analysis adds runoff prediction to the modelling workflow, making the product relevant where rainfall and catchment response need to be considered alongside hydraulic behaviour.
Its strongest distinction is the combination of modelling depth and workflow tooling. A 2D GPU solver supports flood-flow and water-level simulation, while users can set up runs, execute them concurrently and monitor progress. Hydraulic structures such as culverts can also be modelled. Results can be explored through maps, plots and animations, including flood depths, flows, velocities and water levels. Integrations with TUFLOW, EPA SWMM, Delft-FEWS, and WINFAP & ReFH2 help it fit into teams' existing modelling ecosystems. The Python API supports custom tools and automated workflows, particularly useful for repeatable analysis.
Flood Modeller is a focused specialist rather than a general-purpose simulation package: its stated capabilities center on flood hydraulics and hydrology, not discrete-event, system-dynamics, agent-based, finite-element or multiphysics modelling. It runs on Windows, and its cloud option refers to floating license hosting rather than browser-based SaaS. There is no free plan; a 14-day trial is available, while pricing is handled through sales. Teams needing linked river and urban flood analysis, visualization and workflow customization should consider it. Buyers seeking broad simulation methods or browser-first access should look elsewhere.
