Soil Water Balance

Within hydrology soil water balance means the regular inter-action between precipitation and evaporation, run-off and storage-change in an area. Within the soil it means the temporal change of the water content of the soil due to resorption, storage and release of water. These are important factors for different usage, like water management (drinking water, etc.) and planning of handling agricultural land. Within the scope of our research we succeeded to derivate the most important aspects of the complex "soil water balance" presenting them as "functional soil maps" for practical use.

In the navigation there are several functions as part of the soil water balance. They are based on soil profiles (point data) and complex relief factors (area data) done by n-dimensional kriging and multiple regression analyses - except of "recharge of ground water". Besides the mentioned relief factors the entire soil water balance is naturally dependent on many other factors. But in looking at the represented maps/images it is obvious that good results are possible even in using just a few (but good) selected relief factors. This may be an advantage concerning the available data (some soil profiles and a (mostly available) DTM are often the only resource of data). Climate data (evaporation and precipitation) and land-use data give further information to calculate the ground water recharge.
