About HYPE

The hydrological catchment model HYPE simulates water flow and substances on their way from precipitation through soil, river and lakes to the river outlet (Arheimer et al., 2008; Lindström et al., 2009). The catchment is divided into subbasins which in turn are divided into classes (calculation units) depending on land use, soil type and elevation. Read more.

Here SMHI publishes modelled Open Data for inspection and free download from multi-basin and large-scale applications of the HYPE model world wide.

A ‘large-scale hydrological model’ is a numerical code calculating water volume and fluxes over large geographical areas, which encompass many river basins, cross regional and international boundaries, and a number of different geophysical and climatic zones. ‘Multi-basin’ indicates that each geographical domain includes numerous coupled catchments and has a relatively high spatial resolution, although most basins are ungauged. The temporal resolution in the calculations is normally daily.
