Plate 5.4 Natural Runoff 1961–1980

For the 1961 – 1980 period, the average annual specific surface discharge for about 85 % of the water balance basins could be calculated, based on the discharge determined at the basin outlets. The indicated discharge at the basin outlets is equal to the total amount of water runoff at the same positions. To consider the plausibility of these figures, the specific discharge was assessed with regard to the regional hydrology. Results of these plausibility assessments are compiled in the table.
