This paper proposes dividing of Black Sea Catchment Area's river basins into four morpho hydrographic regions - Dobrudja, East Balkan mountain, lowland of Burgas and Strandzha Mountain. It is based on geomorphologic and hydrographic characteristics of rivers and river basins (altitude, valleys, slopes, drainage density, river length, catchment shape, stream orders, and curve of the rivers). The work uses GIS to analyze and data of the rivers and the river basins collected from basic topographic maps. Digital Elevation Model (DEM), created on the base of satellite images, was also used. Based on the data collected for this study some basic hydrographical parameters were calculated. This is the first experiment of morpho-hydrographic dividing of the main catchment area in Bulgaria using river basins like basic units. It shows a way to unify separate river basins into major areas that can be useful for analyzing and research of water resources.
