The main purpose of the research undertaken within small post-glacial catchment was a delimitation of the geosystem functional structure. The base of this research was the study of water and denudation matter migration. According to the different of the morphological, hydrological and hydrogeological conditions the geosystem was divided into 9 types of functional units (subcatchments), that are homogenous of matter migration and denudation cycle. On the basis of results of hydrochemical analysis it was found out that 2 general types of surface waters occurs within researched area. The upper morainic type – acid, low mineralized (similar to rainfall water) and the valley type - significantly higher mineralized with neutral pH values. This difference is strongly connected with hydrogeological and hydrographical structure, which have impact on alimentation of surface waters: rainfall - based or ground water - based. It is also observed connection between delimited functional types of elementary catchments and hydrochemical parameters.
