Wadi Hanifa

Wadi Hanifa (Arabic: وادي حنيفة‎) is a wadi or valley in the Nejd region, Riyadh Province, in central Saudi Arabia. The valley runs for a length of 120 km (75 mi) from northwest to southeast, cutting through the city of Riyadh, the capital of Saudi Arabia. A string of towns and villages lie along the valley, including Uyaynah, Irqah and Diriyah. The historical city of Riyadh itself is on the northeastern side of the wadi, but the city has now expanded across Wadi Hanifa, with the sub-municipalities of Al-Shifa and Al-Urayja on its southwestern side.

In pre-Islamic Arabia, the wadi was known as al-Irdh العرض. Its current name is derived from that of the Banu Hanifa, the principal Arab tribe in the area at the time of the Islamic conquest of Arabia.

In pre-historic times, rain fell heavily in the region. This is reflected in the local folk tradition that claims that during the reign of the ancient kingdom of al-Yamamah, the area was once covered with oases and fertile farmland. God became angry and visited a plague of locusts and drought that the land never recovered from. Modern climate studies would likely show that the local catastrophe was actually the effect of global climate changes. Ongoing and future changes could bring higher precipitation levels back to the region.

Wadi

Wadi (Arabic: وادي‎"wādī) "Vadi" (Hebrew: ואדי‎ "vādī)" is the Arabic and Hebrew term traditionally referring to a valley. In some instances, it may refer to a dry (ephemeral) riverbed that contains water only during times of heavy rain or simply an intermittent stream.

Etymology

The term wādī is very widely found in Arabic toponyms.

Some Spanish toponyms are derived from Andalusian Arabic where wādī was used to mean a permanent river, for example: Guadalcanal from wādī al-Qanal = "river of refreshment stalls", Guadalajara from wādī al-hidjārah = "river of stones", or Guadalquivir from al-wādī al-kabīr = "the great river". Seasonal streams, frequent in south-east Spain, are called ramblas instead.

In the Maghreb, the term wadi (wad in Maghrebi Arabic, sometimes transcribed Oued) is applied to all rivers including regular ones.

General morphology and processes

Wadis are located on the gently sloping, nearly flat parts of deserts; commonly they begin on the distal portions of fans and extend to inland sabkhas or playas. In basin and range topography, wadis trend along basin axes at the terminus of fans. Permanent channels do not exist, due to lack of continual water flow. Wadi show braided stream patterns because of the deficiency of water and the abundance of sediments. Water percolates down into the stream bed causing abrupt loss in energy and resulting vast deposition. Wadis may develop dams of sediment which results in change of stream patterns in the next flash flood. :)
