Abstract in German References
The major aim of this study is to provide hydrogeological and hydrochemical data of the Khaudum National Park/ North-Eastern Namibia. On the basis of 22 data points a groundwater level distribution map was produced. Groundwater levels are relatively shallow in the north and in the west, the groundwater flow is directed easterly towards the Okavango in Botswana. For the study area a mean groundwater recharge of 1.6 persent of the mean annual precipitation turns out by the application of the chloride mass balance method. Two recharged mechanisms are inferred; direct diffuse recharge in soil covered areas and direct relative fast recharge along preferred flow paths in bedrock areas. Both mechanism are confirmed by typical hydrochemical water compositions. Other processes identified are evaporation leading to sulphate enriched water types and catian exchange that produces sodium-bicarbonate water
