Using existing soil data to derive hydraulic parameters for simulation models in environmental studies and in land use planning.
One way of addressing the paucity of soil hydraulic data for simulation modeling is through the use of pedotransfer functions. In this case soil data routinely collected during systematic soil surveys are used to predict hydraulic characteristics.
To derive pedotransfer functions for European soils, 18 Institutes in 10 EU countries participated in the establishment of HYPRES Database.
The first task was to develop a flexible database structure. Next, the database was filled with measured hydraulic characteristics. Finally, the stored data were used for the derivation of classes and continuous pedotransfer functions.
