The main purpose of FloodArea simulation software is the delineation of flooded (inundated) areas.
Calculations are based upon
- a drainage network grid with water levels assigned to it. Though the water levels can vary spatially (e.g. along a river stretch) they remain constant during the simulation process. The water levels can be changed, however, by modifying them between single model runs, or by
- one or more hydrographs at user definable coordinates, or by
- a rainstorm simulation over a wider area, specified by a weighted Grid.
Model results are stored as Grids at user defined intervals, providing for the possibility to reproduce the temporal aspect of the flooding process. The values of the resulting Grids can be stored as absolute height levels or as values relative to the surface. If needed, the flow direction vectors can be output for each individual grid.
Additional parameters can be specified for a simulation run. Flow barriers (e.g. road embankments), which are not represented by the elevation model, can be specified. Locations of dam failures can also be specified determining at which points flow barriers fail, making dike break scenarios possible.
To adapt the flow velocities to real world conditions, the user can specify roughness values.
