Abflussgebiete_HQ100_nach_HWGDischarge areas HQ100 under the Federal Water Act (HWG)
This dataset delineates discharge areas along major watercourses in the German state of Hesse for a 100-year flood event (HQ100). These zones lie within the statutory flood-risk areas defined for first- and second-order watercourses under the Hesse Water Act (HWG). Within these designated flood areas, a distinction is made regarding land use and construction restrictions during flood events. The data is published by the Land Hessen and provides geospatial boundary information relevant to flood risk management, spatial planning, and environmental protection along Hesse's principal rivers and streams.Abflussgebiete an großen Gewässern in Hessen bei einem 100-jährlichen Hochwasserereignis (HQ100).
