There are many mountain rivers in the territory of South Ossetia. The majority of them belong to the Kura drainage basin which flows into the Caspian Sea, the remainder are part of the Rioni River catchment which flows into the Black Sea. The Rachinsky and Lihsky ridges act as the watershed separating the drainage basins into these two seas.
