Zum Zusammenhang von Parametern der Wassermengen und Wasserbeschaffenheit
Authors:U Friedrich  U Grünewald  G Wernecke
Abstract:By means of the quality criteria COD-Mn, NO3?, substances which can be filtered off and components of phosphate at two measuring stations at the river Elbe in the section of Dresden as well as an inflow gauge at a drinking water reservoir in the Eastern Ore Mountains there were investigated correlative connections with hydrological and meteorological quantities. Statistically secured connections between matter-balance and water-balance components were recorded on the basis of regression statements. The large number of the factors to be observed in the development of process-describing matter discharge models is determined by the large number of “causing or influencing quantities”. With respect to continuing investigations, it is recommended to take into account the dynamic character of precipitation and the influence of vegetation more exactly, especially in the case of substance components carried away from areas, as substances which can be filtered off, nitrate, o-phosphate.
