The geography of Iraq is diverse and falls into five main regions: the desert, Upper Mesopotamia, the northern highlands of Iraq, Lower Mesopotamia, and the alluvial plain extending from around Tikrit to the Persian Gulf.
Jordan is situated geographically in West Asia, south of Syria, west of Iraq, northwest of Saudi Arabia, east of Israel and the Palestinian territory of the West Bank. The area is also referred to as the Middle or Near East. The territory of Jordan now covers about 91,880 square kilometres (35,480 sq mi).
Syria is located in West Asia, north of the Arabian Peninsula, at the eastern end of the Mediterranean Sea. It is bordered by Turkey to the north, Lebanon and Israel to the west and southwest, Iraq to the east, and Jordan to the south. It consists of mountain ranges in the west and a steep area inland. In the east is the Syrian Desert and in the south is the Jabal al-Druze Range. The former is bisected by the Euphrates valley. A dam built in 1973 on the Euphrates created a reservoir named Lake Assad, the largest lake in Syria. The highest point in Syria is Mount Hermon on the Lebanese border at 2,814 metres or 9,232 feet. Between the humid Mediterranean coast and the arid desert regions lies a semiarid steep zone extending across three-quarters of the country, which receives hot, dry winds blowing across the desert. Syria is extensively depleted, with 28 percent of the land arable, 4 percent dedicated to permanent crops, 46 percent utilized as meadows and pastures, and only 3 percent forest and woodland.
The Jordan River or River Jordan, also known as Nahr Al-Sharieat, is a 251-kilometre-long (156 mi) river in the Middle East that flows roughly north to south through the Sea of Galilee and on to the Dead Sea. Jordan and the Golan Heights border the river to the east, while Israel and the occupied West Bank lie to its west. Both Jordan and the West Bank derive their names in relation to the river.
The Nahr al-Kabir, also known in Syria as al-Nahr al-Kabir al-Janoubi or in Lebanon simply as the Kebir, is a river in Syria and Lebanon flowing into the Mediterranean Sea at Arida. The river is 77.8 km (48.3 mi) long, and drains a watershed of 954 km2 (368 sq mi). Its headwaters are at the Ain as-Safa spring in Lebanon and it flows through the Homs Gap.
The Yarmuk River is the largest tributary of the Jordan River. It runs in Jordan, Syria and Israel, and drains much of the Hauran plateau. Its main tributaries are the wadis of 'Allan and Ruqqad from the north, Ehreir and Zeizun from the east. Although the Yarmuk is narrow and shallow throughout its course, at its mouth it is nearly as wide as the Jordan, measuring thirty feet in breadth and five in depth. The once celebrated Matthew Bridge used to cross the Yarmuk at its confluence with the Jordan.
The Syrian Desert, also known as the North Arabian Desert, the Jordanian steppe, or the Badiya, is a region of desert, semi-desert and steppe covering 500,000 square kilometers of the Middle East, including parts of southern Syria, eastern Jordan, northern Saudi Arabia, and western Iraq. It accounts for 85% of the land area of Jordan and 55% of Syria. To the south it borders and merges into the Arabian Desert. The land is open, rocky or gravelly desert pavement, cut with occasional wadis.
The Yarkon River, also Yarqon River or Jarkon River, is a river in central Israel. The source of the Yarkon is at Tel Afek (Antipatris), north of Petah Tikva. It flows west through Gush Dan and Tel Aviv's Yarkon Park into the Mediterranean Sea. Its Arabic name, al-Auja, means "the meandering". The Yarkon is the largest coastal river in Israel, at 27.5 km in length.
Tartus Governorate, also transliterated as Tartous Governorate, is one of the 14 governorates of Syria. It is situated in western Syria, bordering Latakia Governorate to the north, Homs and Hama Governorates to the east, Lebanon to the south, and the Mediterranean Sea to the west. It is one of the few governorates in Syria that has an Alawite majority. Sources list the area as 1,890 km² or 1,892 km², with its capital being Tartus.
Latakia Governorate, also transliterated as Ladhakia Governorate, is one of the 14 governorates of Syria. It is situated in western Syria, bordering Turkey's Hatay Province to the north, Idlib and Hama Governorates to the east, Tartus Governorate to the south, and the Mediterranean Sea to the west. Its reported area varies in different sources from 2,297 km2 (887 sq mi) to 2,437 km2 (941 sq mi). The governorate has a population of 1,008,000.
The Zarqa River is the second largest tributary of the lower Jordan River, after the Yarmouk River. It is the third largest river in the region by annual discharge and its watershed encompasses the most densely populated areas east of the Jordan River. The Zarqa rises in springs near Amman, and flows through a deep and broad valley into the Jordan, at an elevation 1,090 metres (3,580 ft) lower.
Water resources management in Syria is confronted with numerous challenges. First, all of the country's major rivers are shared with neighboring countries, and Syria depends to a large extent on the inflow of water from Turkey through the Euphrates and its tributaries. Second, high population growth and urbanisation increase the pressure on water resources, resulting in localized groundwater depletion and pollution, for example in the Ghouta near Damascus. Third, there is no legal framework for integrated water resources management. Finally, the institutions in charge of water resources management are weak, being both highly centralized and fragmented between sectors, and they often lack the power to enforce regulations. Water resources policies have been focused on the construction of dams, the development of irrigated agriculture and occasional interbasin transfers, such as a pipeline to supply drinking water to Aleppo from the Euphrates. There are 165 dams in Syria with a total storage capacity of 19.6 km³. Demand management through metering, higher tariffs, more efficient irrigation technologies and the reduction of non-revenue water in drinking water supply has received less emphasis than supply management. The government implements a large program for the construction of wastewater treatment plants including the use of reclaimed water for irrigation.
