Opis:: The automated extraction of topographic parameters from Digital Elevation Modeis (DEMs) is considered here as an alternative to traditional manual identification of basin's boundaries and river network. The capabilities of DEMs for use in simulations of river network and basin's boundaries are investigated. Processing flow for watershed and river network delineation is elaborated based on IDRISI32 and TOPAZ programs capabilities. This paper presents the methodology of delineation of hydrographic characteristics starting from the basic available source of hypsometric data – topographic map. Critical source area and DEM's resolutions are considered as steering parameters of the quality of simulated hydrographic features. Investigations of regional value of critical source area is indicated as future research path.

Opis:: The paper deals with the theoretical basis, methods and the main results of the investigations of the river system structure (the network of rivers of different orders) transformation. On the basis of a morphometrical analysis of topographical maps from different periods (1855, 1935, 1975, 2005) in the 1:100 000 scale, using the Strahler-Filosofov classification scheme, the structure of representative river systems of Ukrainian Carpathians was investigated. The partial and the total length and number of the streams of every order as well as the correlation between these parameters and bifurcation coefficients were determined. The trends and scales of the river systems structure transformation for the period 1855-2005 were also evaluated. Subject to investigation were the river systems of NE macroslopes of the Carpathlian Mountains.
