Outflow regulation potential (VBK50)

On the basis of the data from the Preliminary Ground Map of Saxony-Anhalt, the evaluation is carried out for the data level drain regulation potential. The soil water balance value according to KARL (2001) is a parameter that maps the drain regulation potential of the soil. It describes the ability of the soil to absorb rain, store it and release it delayed to waters. Related data fields: BWH: Soil water balance value. Value field with regard to outflow regulation potential. The value field ranges from 0.02 to 1.32. BWH_K: Soil water balance value. Classification of outflow regulation potential. Class 1: very small. BWh 0.02-0.26 points. Class 2: it’s small. BWh 0.27-0.48 points. Class 3: means. BWh 0.49-0.69 points. Class 4: it’s up. BWh 0.70-0.90 points. Class 5: very high. BWh more than 0.90 points.
