Balance areas (catchment areas) HADES
This dataset defines the balance areas (catchment areas) that form the middle tier of the hierarchical system describing Switzerland's hydrographical structure, as established by the Hydrological Atlas of Switzerland (HADES). Each balance area typically covers between 100 and 200 square kilometres and serves as a geospatial unit for organising hydrological data such as water balances and runoff. The dataset is published by the Federal Office for the Environment (FOEN) under the Swiss Confederation and provides national coverage. It supports hydrological analysis, water resource management, and other applications requiring standardized catchment boundaries across Switzerland.The balance areas form the middle layer of the system of catchment areas that describe Switzerland’s hydrographical structure (Hydrological Atlas of Switzerland, HADES). They are usually 100-200km² in size.
