Drain regulation potential (VBK50)

Based on the data from the preliminary soil map of Saxony-Anhalt, the evaluation for the data level drain regulation potential is carried out. The soil water balance value according to KARL (2001) is a parameter that reflects the drain regulation potential of the soil. It describes the soil’s ability to absorb, store, and release rain to waters.
