New Groundwater Formation 1990

Statistical Base

The runoff formation and percolation rates in Maps 02.13.3 and 02.13.2, respectively, of the Environmental Atlas constitute the essential basis for the calculation of new groundwater formation rates, broken down by block section. Initially, the runoff and percolation rates on the above maps were recalculated on the basis of the current depth to groundwater (Map 02.07, 2003 of the Environmental Atlas), but with retention of the other initial parameters. Only in areas with shallow depth to groundwater has this recalculation resulted in minor modification of the runoff and percolation rates, respectively. A detailed description of the data bases for these maps can be found in the general text for Map 02.13. In addition, data on runoff measurements to receiving stream as well as data from the literature were used for the calculation.
