3Di enables flood forecasting on the basis of a detailed model. The model is able to predict flooding locations, water depths, and water arrival times, among others. The output of 3Di models is provided in geoTIFF and netCDF form. The results can easily be analysed and processed via a ready-to-use plugin in open GIS software tool QGIS, 

The maps generated by the 3Di models can be used to adjust local risk management. 3Di is a fast, accurate and interactive modelling suite, in which users can easily adapt the model during runs. For example, users can open breaches, or add portable levees to investigate the effects of implementing possible mitigation measures for flood scenarios.
