dc.description.abstract | A hydrogeological model has been developed on the basis of field observat- ions and data collected during the International Hydrological Decade. From water balance studies it was found that half the annual precipitation was lost due to evapotranspiration (400 mm). Nearly 60% of new groundwater percolates through the soil profile during snowmelt. The average melting in spring 1966 was 13.5 mm\/day. Linear velocities through the unsaturated zone were between 17 and 20 cm\/ day. Water mmoves through the saturated zone with an average velocitiy of 10-20 cm\/day, and average natural residence time is close to 30 years. | |
