The article presents the morpholithology types in the Kamchia River basin (Eastern Bulgaria) -the catchment area of the largest Bulgarian river which flows into the Black Sea. These types are determined on the base of information about the relief and lithological substrate. The rocks in the investigated area are divided into groups according to their physical-mechanical and chemical composition, and the relief types are determined in regards to the morphographic features of the catchment area.

As a result of the research a map of morpholithological types (1:200 000) is made. The map shows a considerable variety of the morpholithological types in the Kamchia River basin. This variety determines the appearance of the territory and also influences on the landscape differentiation. The analyses and composition of the morpholithology map are done in GIS environment. For that purpose a GIS database of lithology and relief (topography) of the Kamchia River basin is built as spatial "overlay" analysis is done.
