GEOHYDROLOGICAL SURVEY OF COMMON WATERS IN THE SUDETY MOUNTAINS AND PROBLEMS OF FURTHER INVESTIGATIONS

Summary
The paper presents a state of geohydrological investigations in the Sudety Mountains consisting of all geohydrologic stages e.i. Quaternary, Tertiary, Cretaceous, Triassic, Permian, Carboniferous, Devonian, Older Palaeozoic and pre-Cambrian. Geohydrological survey of particular stages is presented in the table. This survey is irregular and of mainly punctual character. These results from construction of ground water intakes in valleys and intermontane depressions, therefore ground culminations are recognized very little.
Hitherto existing investigations have showed that the most water bearing horizons are in the following stages of the Permian-Mesozoic complex: Cretaceous, Triassic and Permian. They stay in supremacy in hydraulic bonds, that is marked by the presence of common piezometric surface often with artesian features. They are characterized by the higher water bearing in relation to stages and surrounding units mainly included pre-Cambrian. They are also variable considering water bearing due to various lithology causing the presence of small water bearing structures. Within these stages occur fissure springs with higher capacities. The least water bearing horizons are of the pre-Cambrian and Older Palaeozoic stages. Waters in these stages occur mainly in dezintegrated rocks and highly fractured zones.
The dezintegrated rocks however play the main role in water flow. The geohydrological stages of the Cainozoic complex are high quality water reservoir with substantial capacity and great flows. Due to their small useful expansions their importance is limited. Recently the geohydrological survey programme is being realised, which consists of inspection of geohydrological properties in particular stages supply, flow and drainage and preparation of water balance in partial basins. A suitable selection of methods allows to presume that realization of the programme would be a significant step in geohydrological reconaissence of the Sudety.
