Abstract

The authors utilized a "distributed parameter ground water budget' model. The pixel size of the distributed model was 2.25 × 2.25 km, giving 5600 grid elements. Effects of the weather, the afforestation and of the water abstraction from the deep aquifers have been investigated. In the first step changes of the ground water table have been simulated for the period 1961-1987 assuming initial wood coverage of 10% in 1961. Next the wood coverage has been abruptly increased to 20% in 1961. In the second step the changes of the water table in the period of 1961-87 were investigated as influenced by the joint effects of the changes of the weather, the area of forested land (20%) and of the seepage flow into the confined aquifers (assumed to be 30 mm in areal average). Using weighting factors determined on the basis of the results of the model it was concluded that the ground water table was caused mainly (70%) by ground water withdrawal from the confined aquifers, while unfavourable weather conditions and the increase of the ratio of forested land contributed equally (15%-15%) to the decline of the ground water level. -from English summary
