             STEMMUS understood the location of the groundwater depth correctly. The re-calculated groundwater depth is stored in the "depToGWT" variable.
         2) The depToGWT needs to be assigned to a certain soil layer. Because of that assignment, there will be a slight difference between gw_Dep  ...
             and depToGWT (e.g. difference = 1-10 cm  based on the thickness of the soil layer that contains the depToGWT).
