both in north and south Syria are usually closed by sand-bars.
River System and Lakes
The central depression forms the only drainage bed of great length in Syria, and in it flow the three great rivers, Orontes, Litani, and Jordan. In the north several considerable streams come down from the Kurd Dagh, flowing towards the Euphrates.
(a) Northern Syria.—The maritime slopes are mostly well watered, especially in Lebanon, which sends considerable streams to the sea, some of which, such as the Beirut, Kelb, Ibrahim, Kadisha, Barid, Akkar, Kebir (Tripoli), Alrash, and Kebir (Latakia) are perennial.
The Orontes and the Litani rise close together near Baalbek, and flow north and south respectively.
The Orontes (Nahr el-Asi) is the longest river in Syria. Some 20 miles from its source it receives copious affluents, and then, a large stream tapped by irrigation canals, it flows to the artificial reservoir of Lake Homs. Thence it flows to Homs, Hama, and Kalat es-Seijar, where it bends northward through the long marshy plain of El-Ghab, being then supplemented by the waters of several lakes and small perennial streams. The river is thickly fringed with papyrus and other reeds.
Beyond Jisr esh-Shoghu it flows in a deep gorge to Antioch plain, bending westwards to receive the navigable Kara Su, a larger stream than the Orontes itself, flowing from the Lake of Antioch. This lake catches the waters of the upper Kara Su and Afrin Su, which drain the country to the north and east. From Antioch the Orontes pursues its remaining course of 21 miles, and flows to the sea over a bar, being 200 yards wide and 12 ft. deep at its mouth. In winter it is navigable 3 miles from the sea for vessels of 100 tons.
The Litani, after receiving the Yafufe, the Barduni, and the Zair, flows close to the Lebanon base
