Sažetak
Models of geomorphometric parameters and drainage network have widespread usage in many scientific and civilian branches and activities. Their basis’s are Earth’s land surface data which are today mostly represented by digital elevation models (DEM). Objectives of this study are to create models of geomorphometric parameters (slope, aspect and terrain ruggedness) and drainage network for the continental territory of Republic Croatia. Output models are described and analysed giving insights into morphological structures of terrain relief. Models of drainage networks are compared to the existing maps of rivers for quality validation. Furthermore, the differences between output models are addressed and studied depending of the different input DEMs (SRTM, GTOPO30 and ETOPO1), used algorithms (single and multiple flow direction) and other parameters (threshold values). The focus is on studying the sensitivity and influence of input variables on output models to be able to create similar geomorphometric models in the future which would describe reality in the most optimal way.
