The model is implemented as r.sim.water module in GRASS GIS and was applied to the Malá Svinka Basin in Eastern Slovakia where a heavy rainfall (100 mm/hr.) caused a flash flood event with deadly consequences in July 1998. The event was simulated using standard datasets representing elevation, soils and land cover. The results were captured in time series of water depth maps showing gradual changes in water depths across the basin. The hydrological effects of roads in the study area were simulated using the preferential flow feature of the model. This simulation helped to identify source areas contributing to flooding in built-up areas. The implementation in a GIS environment simplifies the data preparation and eventual modification for various scenarios and flood protection measures. The simulation confirmed excellent robustness and flexibility of the method.
