SE.HY Main catchment areas (SVAR2022)

The product SE.HY Main catchment areas consist of polygons that represent the main catchment areas that flow into Sweden. The original definition of a main catchment area consisted of areas having their mouth in the sea and measuring an area of at least 200 km ². The new basis does not always meet the original size criterion, but since the division of main catchment areas is generally accepted, it has been maintained, although with updated boundaries. The product SE.HY Main catchment areas is based on version REPLY 2022:1.2 and contains polygons representing the Swedish main catchment areas.
