Groundwater regeneration dry period (1971-1973)
Description
New groundwater formation from precipitation is a residual component of the water balance. It is described as the percentage of precipitation height reduced by actual evaporation and rapid drainage component. The groundwater regeneration rates shown in the map are the result of modelling with qualitatively different input data. In each case, the best possible data base available in Bavaria was used in order to be able to make as uniform statements as possible. Therefore, data sets from different scale ranges were used together for modeling. Examples are on the one hand the highly generalised overview map on the 1:1,000,000 scale and on the other hand the detailed digital terrain model in the 50 m grid. Furthermore, data has been used, some of which can also show significant regional differences in quality (e.g. groundwater flux level, regionalised station data of the different climate parameters). For this reason, the map sheet “groundwater reformation dry period (1971-1973)” represents a large-scale overview and allows a description of the regional conditions appropriate to the scale of 1:500,000. The use of the raster-related individual values for detailed statements is not methodically permissible.
