These are internal short rivers with an East-West lateral orientation spilling into the Mediterranean, except for the two trans-border rivers which are the Orontes River (Nahr el Aassi) crossing towards Syria and the Hasbani River crossing towards Palestine. The rivers and water basins maintain the Lebanese ecosystem and irrigate low and middle elevation areas of Mount Lebanon, as well as in the Bekaa valley. Besides, rivers enhance the flora and fauna of the country, particularly in deep valleys where local climate is softer. 2.10 Lebanese river system –
