Dataset description

A catchment area is the area from which water is drained upstream of a certain point. The catchment area is bounded by hill backs, which divide the flow from rain and melt water in different directions. The watershed is the limit of the catchment area.For a river basin, the water flow in the outlet can be calculated using information about the area, land, lakes, watercourse lengths, precipitation, evaporation, snow storage, etc. A main catchment area is defined by its estuary in the sea and an area of at least 200 km². The product, based on version SVAR 2016:6, contains 232 polygons representing the Swedish main river basins and coastal areas between them as well as parts of the main Norwegian river basins.
