Comparative analysis of physiographic parameters for a drainage basin

U članku je prikazana usporedba fiziografskih parametara srednje visine i srednjeg pada sliva proračunanih tradicionalnim i suvremenim metodama. Pri proračunu primijenjeni su rasterski i vektorski modeli terena. Proračun, statistička obrada i usporedba rezultata provedeni su za 62 podsliva rijeke Orljave koristeći se dostupnim komercijalnim GIS alatima. Na osnovi statističke obrade rezultata određeni su izrazi za proračun srednjeg pada sliva i njihovi intervali povjerenja.The comparative analysis of physiographic parameters for a drainage basin of medium height and gradient, based on traditional and modern calculation methods, is presented. Raster and vectorial terrain models are applied in the analysis. The analysis, statistical treatment, and comparison of results, were conducted for 62 sub-drainage basins of the Orljava river using commercially available GIS tools. Expressions for calculating the mean gradient of the drainage basin, and their confidence intervals, were determined based on statistical results
