Seamlessly model rivers, floodplains and urban drainage systems with Flood Modeller’s industry-leading solvers
Flood modelling forms a vital part of understanding flood risk and hazards. This means undertaking the evaluation and design of flood mitigation solutions that address both current and potential future flood risk conditions. Flood Modelling can also be used to provide flood forecasts, enabling communities to be prepared for and respond to impending danger.
Using historical and real-time river, rainfall and sea level data, alongside data that represents the physical environment (i.e. river and drainage networks, floodplains and structures), the likelihood and probability of flooding for a specific area can be assessed.
Flood Modeller allows you to seamlessly model rivers, floodplains and urban drainage systems
Uses river, rainfall and sea level data, alongside LiDAR, to predict the probability of flooding
Flood Modeller is suitable for a wide range of modelling applications, from calculating simple backwater profiles to modelling entire catchments
Flood Modeller’s 2D solvers are designed to work either standalone or can be dynamically linked to the 1D river or 1D urban solvers
Flood Modeller’s intuitive GIS-like interface provides a wide-range of model building tools, as well as pre and post-processing operations
Whether you need to build a simple 1D model of a rural river channel, develop a 1D-2D linked flood model for an urban area, or undertake fully integrated catchment modelling which incorporates sewer networks and other drainage systems, Flood Modeller has the functionality to meet your needs.
The software has been subjected to extensive testing and benchmarking against observations, analytical solutions and other modelling software. These include the exercises that were undertaken by the Environment Agency (England) in 2003 and 2013 which showed Flood Modeller to have high accuracy in the tests.
Flood Modeller provides a fully integrated 1D and 2D modelling solution which is suitable for a wide range of engineering and environmental applications. Its intuitive GIS-like interface provides a wide-range of model building tools, as well as pre and post-processing operations.
Its industry-leading 1D river solvers provide a comprehensive range of methods for simulating flows and levels in open channels, floodplains, reservoirs and estuaries. Its steady and unsteady solvers are suited to subcritical, supercritical and transitional flow regimes to confidently apply them to applications, ranging from steep river flows to tidally influenced estuaries.
Extensive colour ramp options for extent, depth, water level and velocity data (including time series data) make it easy to understand your results and how they evolve over time.
The 1D river solvers provide a comprehensive range of hydraulic structures, including gates, abstractions, weirs and pumps. Structures can be operated using logical rules for applications such as controlling the gate opening of a sluice or turning a pump on or off.
Hydrological boundary units are also provided as standard, simulating rainfall-runoff for a range of methods. Any hydrograph can be input to the software to take into account local hydrological methods. Direct rainfall inputs can also be applied.
The 1D urban solver combines the advanced features of Flood Modeller with the widely accepted and Federal Emergency Management Agency (FEMA) approved United States Environmental Protection Agency’s (EPA) Storm Water Management Model (SWMM). This allows users to combine surface and subsurface flow and undertake a detailed and integrated understanding of flood risk in urban areas and develop catchment-based solutions.
Flood Modeller provides three advanced 2D numerical solvers which are used to calculate water depth and ‘depth averaged’ velocity on a grid or mesh. LiDAR is used to provide high-resolution datasets, which can create Digital Surface Models (DSMs) and Digital Terrain Models (DTMs).
The robust 2D ADI solver can be applied to fluvial, overland, estuarine and coastal modelling problems where the flow is not rapidly changing. It is used globally for surface water modelling, local and catchment scale assessments, flood mapping, embankment and asset failure and other flood risk management studies.
Explore 2D results in the core map interface, overlaid on the built-in background mapping and any other contextual layers. The built-in animation functions enable you to view and record a complete picture of your model results.
The 2D TVD solver provides accurate representation of 2D ‘shocks’ (rapid changes in water surface profile) and is also capable of modelling subcritical flow. It is regularly used for modelling dam breach, levee/embankment failure, very steep catchments, or flow down spillways as it generates more stable and smoother solutions as it’s particularly suited to modelling steep changes in velocity and water level.
The FAST solver is an innovative flood inundation modelling tool designed to allow quick assessment of flooding using simplified hydraulics. It provides results in seconds or minutes as opposed to hours or days, which are up to 1,000 times faster than traditional 2D models.
