• Description:
  This article is an attempt of a presentation concerning the springs of the upper part of the Bystrzyca Dusznicka drainage basin against a background of the tectonic structure and geology. All the measurements and mapping of the surface hydrolographical objects were carried out in July 1993. The most important tectonic element of the researched area, which determines the spatial layout and the features of the springs, seems to be the Zieleniec overthrust consisting of the folded Proterozoik mica slates. The lower edge of its overthrust is at a height of 800 m. The rest of the drainage basin is formed of upper Cretaceous sediments dipping in the inner-Sudeten syncline. Later alpine deformations modified the geological structure of this area. The faults formed in such a way as to form 2 systems of crackings: the parallelone and slanted one running NW to SE. The Bystrzyca Dusznicka valley which runs alongside the axis of the drainage basin shows the water-gap character. In the researched area the authors observed either subsurface water in the mantle rocks, or fissure water circulating in the deeper metamorphic rocks. The upper Cretaceous porous sandstones form the most capacious underground water basin. Each water-bearing underground water horizon is separated with marly rocks. From among springs of the researched area three basic types of them were distinguished: fissure, fissure-mantle and mantle springs. Five big fissure springs ranged between 18 and 36 dm3• S-l form the source of the Bystrzyca Dusznicka river. In the drainage basin area over 100 outflows were recorded of which more than 20 were classified as spring sappings. The springs with the biggest average yield equal 2,5 dm3• S-I found in the escarpment zone of the mentioned above overthrust; whereas alongside the eastern undercut there are many small springs and spring sappings of the valley and channel character. Value of the correlation coefficient between spring water temperature and its altitude is equal to r =-0,62. It testifies to the evident inversely proportional relationship between these factors. In the upper parts of the basin fissure springs dominate whereas in the lower parts - hotter mantle ones do. At the height-interval of 700-900 m there are either mantle springs or fissure ones. The conclusions which flow from this article prove the thesis that in the mountainous areas the following factors determine the regime and localization of springs: tectonics, geology and relief of the researched area.;
  Opracowanie niniejsze jest próbą prezentacji źródeł zlewni górnej Bystrzycy Dusznickiej na tle budowy geologicznej i tektoniki obszaru. W opracowaniu zwrócono szczególną uwagę na termikę wód źródlanych i związek występowania obszarów źródliskowych z budową geologiczną zlewni.
