Geomorphological Caracteristics of Lower Part of Sutla RIver Valley

Dolina rijeke Sutle oblikovana je na području SZ Hrvatske u sklopu Panonskog bazena. Geomorfološkom analizom i sintezom te metodom geomorfološkog kartiranja istražena je dolina donjeg toka rijeke Sutle od Kumrovečke zavale do ušća u Savu. U sklopu geomorfološke analize obrađena su morfometrijska i morfogenetska obilježja reljefa. Na temelju digitalnog modela reljefa izračunati su rasterski slojevi vrijednosti hipsometrije, nagiba padina, ekspozicije i vertikalne raščlanjenosti reljefa. Razlučeni su dominantni morfogenetski procesi oblikovanja reljefa: strukturnogeomorfološki i egzogeomorfološki. Dolina rijeke Sutle ima kompozitno obilježje što je izraz njenog složenog geomorfološkog razvoja. U oblikovanju doline odlučujući su utjecaj imali fluviodenudacijski, fluvijalni procesi i tektonika. Reljef doline Sutle u velikoj je mjeri modificiran čovjekovim djelovanjem, stoga je izvršena analiza oblika korištenja zemljišta kako bi se utvrdio utjecaj različitog iskorištavanja zemljišta na intenzitet egzogeomorfoloških procesa.River Sutla valley was developed as a part of Panonian basin in NW part of Croatia. The research of lower part of river Sutla valley from plain of Kumrovec till the firth has been made using analysis, synthesis and the methods of geomorphological mapping. As part of the geomorphological analysis there are discussed morphometric and morphogenetic characteristics of relief. Based on the digital elevation model, raster layers were calculated for the values of elevation, slope angle, aspect and exposure. The dominant morphogenetic processes of the relief formation (structural geomorphological and exogeomorphological) were distinguished. Character of valley is complex. Valley is of a poligenetic origin, which means that in its modeling fluvial denudation processes and tectonic had the major influence. Relief of Sutla valley was largely modified by human activities. In order to determinate the impact of different land use on intensity of exogeomorphological processes, the analysis of land use was made
