The runoff formation and percolation rates in Maps 02.13.3 and 02.13.2, respectively, of the Environmental Atlas (Edition 2019) constitute the essential basis for the calculation of new groundwater formation rates differentiated by area. A detailed description of the databases for these maps can be found in the text for Map 02.13. In addition, data on runoff measurements to receiving waters as well as data from the literature were used for the calculation.
