Central Messenian Plain
The Central Messenian Plain, also commonly referred to as the Sabamic Plain, is a geomorphological region of Messenia, one of the subcontinent's two major plains systems. The Plain is roughly equivalent to the basins of the rivers Gaste and Génestre, as well a small part of the Védomagne catchment after its confluence with the Génestre in eastern Dordanie (the region of Lower Védomagne).
The Central Messenian Plain is generally divided into three sub-entites: (1) the Sabamic or Savamese Plain (also Sabamia), which corresponds to the Lower Gaste basin downstream of Lake Carles, the lower parts of the Génestre basin, and Lower Védomagne; (2) the Upper Gaste Basin upstream of Lake Carles; and (3) the Upper Génestre Basin, generally defined as starting upstream of the Celorio Falls. The Upper Gaste Basin is often also known as the Ellish Plain, while the upper reaches of the Upper Génestre Basin are known as the Embute Plain.
The plain and its sub-components form a large inverted U-shape that wrap around the mountains of the Galban Massif. Clock-wise from the north-east it is bounded by the Severnistines, various sub-ranges of the Valderfall-Leucasians (Verbian Uplands, Cordillera, the Leucasians proper, etc.), parts of the Galban Massif, the Otway Ridge, the Aphrasians, the Odannaigh Uplands, the Rindarian Range, and the Massif Cardussien.
