In addition, concepts that exist to protect people from floods having a look at the catchment, the rivers and the settlements at risk. Following the so-called flood risk cycle, prevention, protection and preparation measures will be shown. This course will also introduce the fundamental concepts related to hydrological modeling including surface and groundwater modeling. Topics will include a historical perspective on hydrologic simulation, model classification and state-of-the-art models. In addition, geo-informatics tools that help improve watershed management will be taught.
