Strahler stream order
This dataset provides the Strahler stream order for Switzerland's hydrographic network, a classification that indicates the degree of branching and hierarchical structure of watercourses. Under the Strahler system, headwater sources are assigned order 1, and the order increases where two tributaries of equal order converge, providing a standardized measure of stream size and network complexity. The data underpins morphological studies and descriptions of watercourses, supporting hydrological and environmental analysis. It is published by the Swiss Federal Office for the Environment (BAFU) as part of Switzerland's national environmental and water-related geospatial data offering, freely accessible without authentication.}}[NO_AUTH]{The stream order according to Strahler specifies the degree of branching of a hydrographic network.
