Anforderungen an die Gütebewirtschaftung von Oberflächengewässern in tropischen und subtropischen Klimaten

A survey is given of the special conditions and their effects by means of a large number of examples. There should be pointed out especially the possible mass development of higher aquatic plants, partly high concentrations of turbidity-causing substances, the lack of oxygen even at slight water depths as well as the often high contents of pathogenic agents and a pronounced thermal stratification in storage reservoirs. Conclusions for the quality management are derived.
