Morphometric analysis of the drainage network in the northeastern slopes of the Sashtinska Gredna Gora Mountain

The following case study aims to analyze morphometric properties of the drainage network in selected river basins, covering the northeastern parts of the Sashtinska Sredna Gora Mountain. Drainage network is extracted from а digital elevation model (DEM). Several morphometric linear and areal parameters are calculated and interpreted – number of streams, total stream length, bifurcation ratio, circularity ratio drainage density, stream frequency, Melton ratio, hypsometric integral, etc. The hierarchy of tributaries and main rivers is also discussed.
