Multiple areas

Using Multiple Areas

You can simulate multiple areas within one FastFlood model setup. Each of these has a seperate set of input maps and settings. Mitigation features and discharge conditions are shared by default, but can be specified to work for only a single specific area. There are several use-cases for the multi-area feature.

1. Multiple catchment automization
2. Cascading resolution model domains

Multiple catchment automization

You can run multiple catchments in a single setup. In upcoming versions of the model, simulation automization will be possible, for setups such as calibration or rapid assessment.

Cascaded resolution model domains

The second use-case for this feature occurs in case of large simulation areas. Simulating large catchments can increase computation time for unneccesary detail over a large area. As a solution, one might set up a course-scale simulation for the larger area (e.g. catchment). This predicts hydrology and channel discharge. A second simulation area can then be set up with a discharge boundary condition that depends on the output of the catchment simulation.
