HÜK200 - HÜK200: Usable field capacity - OGC API Features

In the context of the implementation of the EU Water Framework Directive, the first and further description of the groundwater bodies of Rhineland-Palatinate represents an inventory of the subsoil of the river basins in Rhineland-Palatinate with the aim of recording those groundwater bodies for which there is a risk of not achieving the environmental objectives under Article 4 of the EU Water Framework Directive. The description is based on the Hydrogeological Overview Map of Germany (HÜK 200). It was established in 2001 by the State Geological Services of Germany (SGD) and the Federal Institute for Geosciences and Natural Resources (BGR) on a scale of 1: 200,000 in the sheet cuts of the TK 200. The contents correspond to HÜK 200 of the BGR. The usable field capacity (nFK) is the amount of water that a soil can retain against gravity and that is available for vegetation. It is given in mm (l/m2) and can refer to various reference variables (effective root space, 1 meter, etc.). Together with the meteorological parameters, it controls the amount of leachate and is therefore an important calculation parameter for the determination of groundwater recharge.
