3D Soil Hydraulic Database of Europe at 250 m resolution
TOTH Brigitta | WEYNANTS Mélanie Marie A | PÁSZTOR László | HENGL Tomislav
Soil hydraulic properties are required in various modelling schemes. We propose a consistent spatial soil hydraulic database at 7 soil depths up to 2 m calculated for Europe based on SoilGrids250m and 1km datasets and pedotransfer functions trained on the European Hydropedological Data Inventory (EU-HYDI). Saturated water content, water content at field capacity and wilting point, saturated hydraulic conductivity and Mualem-van Genuchten parameters for the description of the moisture retention and unsaturated hydraulic conductivity curves have been predicted. The derived 3D soil hydraulic layers (EU-SoilHydroGrids ver1.0) can be used for environmental modelling purposes at catchment or continental scale in Europe. Currently only EU-SoilHydroGrids provides information on the most frequently required soil hydraulic properties with full European coverage up to 2 m depth.
