Damage calculator

Use grid and property data to ascertain flood depths at each property location, and combine these data with the associated depth-damage curves to calculate the damages to properties in your study area.

1D flood calculator

An easy method for quickly converting your 1D model outputs into a variety of standard GIS formats, enabling the impacts from your modelled data to be visualised and interpreted on a map.

HEC-RAS import

Flood Modeller allows you to import cross-sections defined in HEC-RAS models, automatically converting them to Flood Modeller 1D cross sections, removing the manual conversion process.

Multiple domains

Allows any number of 2D domains with different cell sizes to be built into a model. This is extremely useful when a model incorporates urbanised and rural floodplains which require varying levels of detail.

Layer converter

Improves modelling efficiency by allowing users to take advantage of different datasets. It converts existing GIS datasets (shapefiles or grids) into different formats, including grid shapefiles, outline shapefiles, Google Earth files or alternative grid types.

Results extractor

Extract model results across different return periods, storm durations and model runs. Checks are carried out to ensure that the results are valid which are then pre-formatted for report tables with additional data drawn from the model.

Health checker

Removes common modelling errors and assists in making models run faster, and with better convergence. It also incorporates some automatic and user assisted error fixing which allows the user to solve common modelling problems.

2D event duration

Interrogate 2D model outputs to ascertain how long the modelled floodplain remains wet or maintains a depth above a specified threshold.

Batch runner

Quickly build up a batch run of multiple simulations from your project. The simulations are managed by Flood Modeller and are run concurrently or sequentially depending on available processors. A batch can be made up of any combination of model types, including TUFLOW.

Sediment transport

Predict the sediment transport rates and patterns of erosion/deposition in river channels or to study sedimentation problems for both uniform and graded sediments. 

Water quality

Simulate advection / diffusion of conservative and decaying pollutants, water temperature, cohesive sediment transport, interaction of quality determinands with sediments, phytoplankton and pH.

Automatic interpolator

Specify a maximum spacing between cross-sections and apply interpolate units, where necessary, to the model or selected reach(es). This is appropriate where, for stability purposes, finer resolution of the watercourse is required and survey data is not available.

1D simulation builder

Improve the speed of common model building and editing tasks using the 1D simulation builder. Automatically build multiple 1D simulations from combinations of network files, event files and TUFLOW control files.

Reservoir and spill generator

Seamlessly interrogate underlying Digital Terrain Model (DTM) elevations to create new spill and reservoir (floodplain) 1D units within your model.

Calibration file editor

Remove the manual process of having to create calibration text files from specified data. As well as preventing mistakes, it improves the efficiency of the user, and allows modelled and observed quantities to be easily compared for calibration and verification purposes.

Conveyance plotter

Display the calculated channel conveyance against stage for a river section unit, either on a cross-section plot or on its own. This provides the modeller with a quick reference to check that conveyance increases monotonically and smoothly with stage.

Global edit

Quickly investigate sensitivity of 1D models to selected parameters, such as roughness, by editing entire networks in a single operation, e.g. increasing values by 10%.

Optimise storm duration

Automatically vary storm durations in all hydrological boundaries (FEH or ReFH) within a 1D model to ascertain the durations that lead to maximum impact at a specified location.

EACSD import

Import validated survey data in the standard Environment Agency (England) Channel Survey Data (CSD) format directly into Flood Modeller.

Mapping All Sources

Quantify combined flood risk using flood maps from a number of sources or different probabilities of flooding. The outputs can also be used to inform whether more local modelling is required for areas of high risk or high uncertainty.
