Sosch
The whole area of the district belongs to the drainage basin of the Sozh River, a major right tributary of the Dnieper. The Sozh crosses the district from the north to the southwest, crossing into Belarus. The principal tributaries of the Sozh within the district are the Berezina River (left) and the Lyza River (right). Most of the area of the district is flat, and in the northwest the outskirts of the Smolensk Upland dominate the landscape.
