Task of hydrogeography in utilization and protection of water resources =Úkoly hydrogeografie při využívání a ochraně vodních zdrjů

Abstract

Hydrogeography should mainly solve problems related to the continuously increasing demands for water as one of the natural resources extremely important for the human society. The disproportion between the water consumption and accessible water resources is increasing due to an extremely uneven distribution of water storages on as well as under the surface of the earth, bath as a whole and on the territories of individual states. Most different landscape types occur on the earth surface differing from each other not only by their natural conditions but also by the extent of the changes due to human activities. The volume of the water storage In a water body, its quality and utilization for other purposes is associated with the diversity of natural conditions and the intensity of antropogenic interferences with the landscape
