River Typology for Switzerland
This dataset provides a typology of Swiss rivers, classifying watercourses according to abiotic, physiographic criteria such as natural landscape and hydrological characteristics, without accounting for human impacts. Published by the Swiss Confederation, it offers national-scale coverage of river types across Switzerland. The typology serves as a basis for assessing the ecological state of rivers and provides guidance for planning rehabilitation measures, supporting environmental and water management work at federal and cantonal levels.The typology of rivers groups the diversity of Swiss rivers according to abiotic, physiographic criteria, not considering anthropogenic impacts. They are a basis for assessment of the ecological state of rivers and represent a useful guidance for rehabilitation measures.
