In order to get an spatial statement over the groundwater temperature distribution, a Kriging-Interpolation based on a Variogram analysis was calculated. Prerequisite for the execution of a Variogram analysis is that the groundwater temperature is regionalized that can be regarded as the realization of a coincidence-function. A regionalized variable distinguishes itself through its relationship to its neighboring points (Akim & Siemes, 1988). With a Variogram analysis it is tried to characterize these structure-characteristics and to use them mathematically. The results are integrated as input-parameters into the Kriging-Interpolation. The interpolation delivers a freely selectable grid, whose junction points return the calculated groundwater-temperatures.
