This folder contain both GIS data with simulation results, calibrationstatistics and model set up data from The National Water Resources model, version 2019 (DK-model2019) and the acctual modelset up in MIKESHE/MikeHYDRO. The hydrogeological layers in DKmodel2019 are also available for download in ascii format, and rasterdata as geotiff's. The DK-model is a mechanistically, transient and spatially distributed groundwater-surface water model to advance the assessment of groundwater quantitative status accounting for interactions with surface water and anthropogenic changes, such as extraction strategies and land use, as well as climate change. It includes a 3D hydrogeological description of the entire 43.000 km2 in Denmark and since 1996 gradually updated based on detailed studies by regional water authorities and other national research institutions. By incorporating new knowledge, the model is kept up to date and ensures a common basis for assessments at various scales by different authorities. https://vandmodel.dk/
