Why use Flood Modeller?
Whether analysing river flooding, surface water flooding, sewer surcharge, reservoir exceedance, or coastal inundation, Flood Modeller accurately represents the interaction between hydraulic systems and the floodplain. The result is reliable representation of flood extents, water levels, flow velocities, and flood hazard to support flood mapping, flood risk assessment, and infrastructure resilience planning.
Integrated 1D-2D modelling
Accurately represent the interaction between rivers, floodplains, and drainage systems, within a single model. By dynamically linking 1D and 2D domains, Flood Modeller captures complex flood behaviour more realistically, delivering greater confidence in flood risk assessments, infrastructure design, and flood mitigation strategies.
Scenario and simulation management
Effortlessly create, manage, and compare hundreds of simulations. Evaluate return periods, climate change allowances, rainfall events, catchment conditions, and design options while monitoring model performance and diagnostics in real time.
GPU-accelerated performance
Complete large-scale hydraulic simulations in a fraction of the time required by traditional CPU-only modelling. Flood Modeller's GPU-enabled 2D solver accelerates project delivery, reduces computational costs, and makes it practical to assess more scenarios, more frequently.
Model validation and diagnostics
Identify issues before they impact results with detailed diagnostics, warnings, convergence monitoring, and quality assurance tools. Validate model performance, troubleshoot simulations quickly, and improve confidence in your hydraulic analysis.
Climate change scenario analysis
Quickly assess the impact of future climate change allowances, rainfall scenarios, and adaptation measures. Compare multiple scenarios side-by-side to better understand future flood risk and support long-term infrastructure planning.
Hydraulic structures
Represent complex hydraulic systems with confidence using a comprehensive library of bridges, culverts, weirs, sluices, pumps, spillways, and more. Accurately model both in-channel and subsurface flows, automate operational controls, and seamlessly connect structures within your 1D and 2D domains.
