Springs of the North-Western part of the Śnieżnik Massif
Languages of publication
The evaluation of the spring regime lets us characterize some hydrogeological features of
the researched area and determine the influence of the so called point drainage on a layout
and quantity of water which supplies the river network. It refers especially to the mountaineous
areas. A good example is the metamorphic Śnieżnik Massif, where due to the lack of
representative hydrogeological bore-holes a number of springs are the only sign of the
underground water circulation.
The hydrographical mapping of the researched area was carried out in July 1994. This
period was characterized by an evident shortage of precipitations and by high temperatures
of air. They researched the Wilczka drainage basin down to the Wilkanów profile and all
the upper parts of the Nowinka, Domaszkowski Potok, Szklarka and Czarna Woda drainage
basins (fig. 1). There were observed 212 natural underground water outflows there, of which
162 were real springs, 38 sapping springs and 12 bog-springs.
The analysis of the observed spatial diversity of the underground water outflows was
carried out basing on the elementary measures referred to the areas of the autochthonous
and defTerenliated drainage basins. Those basic measures are: springability coefficient, spring
water runofT modulus and the participation of the spring water in the combined runoff (fig.
2, 3, 4, 5). They noticed evident connections with relief, geology Le. characteristics of the
underground water basins, drained by springs.
The vertical diversity of the researched springs was examined either in the zonal
height-intervals or actual altitude (precise fixing of an altitude) (fig. 6, 7, 8, 9). The quantity
of the outflows and their features (temperature, yield) were estimated on the statistical
characteristics of the studied series. There were not observed any very evident connections of
the analyzed characteristics with an altitude. The authors observed a tendency to constitute
height-intervals in which the character and the regime of the springs are similar. The causes
for such a state should be searched in orographic and geological features, which are combined
with the occurence of definite groups of outflows on the proper altitude.
