- The aim of the study was a hydromorphological valorisation of the river valley in the Roztocze region using the British method - River Habitat Survey (RHS). As a result of field research two numerical indicators HMS (Habitat Modification Score) and HQA (Habitat Quality Assessment) were identified and purity water classes were defined. The river did not fulfil the requirements of the Water Framework Directive, because its state was defined as poor and moderate. On the base of physical and chemical parameters, in the majority of water studied the watercourses were classified to the first class of purity. Only in one segment waters were below the first class, or even out of class.
