Mean runoff (m³/s) and flow regime types for the river network of Switzerland
This dataset provides modeled mean runoff values, in cubic metres per second, for the entire Swiss river network, covering monthly and annual averages. It also classifies flow regime types for each river segment. Known as MQ-GWN-CH, it represents a medium-scale hydrological model covering all of Switzerland, though runoff values are omitted for small watersheds below a defined area threshold. The dataset is published by the Swiss Federal Office for the Environment (BAFU) under the Swiss Confederation, and supports hydrological analysis, water resource planning, and environmental monitoring at the national level.For the entire Swiss river network natural runoff (m³/s) values (monthly and annual means) have been modeled and the flow regime types determined. «MQ-GWN-CH» constitutes a dataset for the entire medium-scale river network of Switzerland. No runoff values are given for rivers with watershed areas <…
