Al-Ghab Plain

The Ghab Plain (

Muhradah, around 25 km north-west of Hama.^[1]^[2]

The valley was flooded for centuries by the waters of the Orontes River, which rendered it a swamp.^[3]^[4] The "Ghab project", beginning in the 1950s, drained the valley to make it habitable, arable land,^[5] providing an extra 41,000 hectares (160 sq mi) of irrigated farmland.^[6]

The valley separates the

Zawiyah mountain range and the plateau region to the east.^[1] It is 63 kilometres (39 mi) long and 12.1 kilometres (7.5 mi) wide.^[3]

Fisheries

Before its drainage, the Ghab was the center of the catfish (

Silurus glanis) (sallōr or samak aswad) fisheries of the Orontes valley.^[7]

Ghab project

The project started in 1953 and is considered one of the most important hydraulic projects in northern Syria. Owing to a slight slope (0.10%) in the Orontes in the area of al-Asharinah, the river did not provide enough water to the surrounding territories. In Ancient times, several major dykes and dams had been built on the Orontes river in the Ghab plain, transforming the western end of the region from marshes into arable farming land. The Syrian government intended to replicate this plan themselves. The project drained the plain where the River Orontes flowed. The plain was entirely drained in 1968 and provided 11,000 families with lands.^[5]

The Ghab project made large areas suitable for agriculture, and new irrigation systems were employed. The system included

Mahardah, Zayzun, Qarqur and other villages. The dam at Mahardah, built in 1961, is 40 metres (130 ft) high, and 200 metres (660 ft) long and holds 65,000,000 cubic metres (85,000,000 cu yd) of water.^[5] The Zeyzoun Dam

, built in 1996, was 32 metres (105 ft) high and held a maximum of 71,000,000 cubic metres (93,000,000 cu yd) of water; it failed in June 2002, leading to the deaths of 22 people and the displacement of over 2,000 as a large hole opened in the embankment and flooded 80 square kilometres (31 sq mi) of the countryside downstream.

Other advantages of the Ghab project were the improvements in the systems of communication through the building of road and rail networks, previously not possible due to the swamps. In addition, malaria decreased because there was no longer stagnant water.^[5]

Al-Ruj Plain

Northeast of the Ghab Plain is found another smaller plain, known as al-Ruj Plain (Rouj basin).^[8] It is located between the Ghab Plain, and Amouk Plain. This is an agriculturally prosperous enclave just west of the town of Idlib.^[2] Many ancient archaeological sites are located there.
