TŁO HYDROCHEMICZNE WÓD W ZLEWNI GÓRNEJ WOŁOSATKI W BIESZCZADACH WYSOKICH

Abstract

HYDROCHEMICAL BACKGROUND OF THE UPPER WOŁOSATKA CATCHMENT, HIGH BIESZCZADY MTS.Abstract. The study area covered 9.5 km2 of the upper Wo³osatka catchment in the High Bieszczady Mts. The area is composed of flysch sediments of the Krosno beds, folded and transected by deep faults. Hydrochemical background has been defined with regard to stream and ground waters. The latter were represented by spring and swamp water. The hydrochemical background was assumed as a range between the 10th and 90th percentiles. The results demonstrate a moderate variability of the water chemical composition. Low mineralization and other parameters reflect both the origin of waters from current precipitation and their shallow circulation within the rocks.
