Wadi Hanifa Riyadh Saudi Arabia

Wadi Hanifa is an in the Nejd region in central Saudi Arabia. The word wadi means valley. This video is in the Riyadh area. The valley runs for a length of 120 km (75 mi) from north to south, cutting through the city of Riyadh, which is the capital of Saudi Arabia. The valley takes its name from the ancient Arab tribe of Banu Hanifa, who were the main tribe in the area at the dawn of Islam, though in those days the valley was known as al-Irdh. A string of towns and villages lie along the valley, including Uyaynah, Jubaila, Irqah, Diriyah, and Ha'ir.

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.

Temperatures in summer reach an average of 42.9 °C (109.2 °F), and precipitation averages only 60 millimetres (2.4 in) per year in the driest places. Rain falls with great intensity for short periods, causing flash floods. The nature of the dry, warm climate leads to a high percentage of the scarce rainfall being instantly evaporated. That which remains mostly ends up as groundwater. While abundant, the levels of the water table are being tested by the rapid growth the city of Riyadh has seen in the past fifty years, from a population of 150,000 in 1960 to an estimated 5 million today.

While the wadi has traditionally been dry except for during times of flooding, the construction of Riyadh's first large sewage treatment facility in 1982 has channeled 400,000-650,000 cubic meters of runoff downstream daily, creating a constantly expanding area of small lakes south of Riyadh. A new green corridor nearly 100 kilometers long has been formed. The Saudi government and the Ar-Riyad Development Authority appointed Buro Happold and Moriyama & Teshima architects [1] to plan the preservation of the wetlands of the Wadi Hanifa, as they had become a popular destination for recreational activities such as fishing and picnicking and have also become a stop for migratory birds. The government has invested over $100 million (US) into an environmental rehabilitation project. This includes the construction of dams to regulate water flow, new limits on land use such as the banning of such commercial activities as quarrying and the planting of reeds to further purify the treated and untreated sewage. The completed project won the 2010 Aga Khan Award for Architecture [2]

The increase in surface water has led to widespread date palm cultivation along the banks of the wadi. The treated water is given free of charge from the government to farmers which has led to much higher yields. More importantly for the economy, the government uses much of the water to run one of the largest oil refineries in the country. The city of Riyadh also pumps a portion back into the city to irrigate its public gardens and parks.

Dude how could you do that!

It's summer time, It must have been very hot!

Anyway, back to the valley, I'm Saudi and I have never been to this valley, it's just another lie that Riyadh Municipality worked slightly on in order to get people to believe that Riyadh has some recreational sites! Why don't they just turn the old airport into a huge park, where people take leisurely walks, ride bikes and run, just like Central park in NYC and Sultanahmet park in Istanbul! Someone find me a job there LOL

nice

you should go to Aseer region in the western south of saudi arabia..the main city is Abha..and you will have very different idea about saudi arabia..it is 3000 meters above the level of sea.

a lot of greens, forests,farms,nice weather,some lakes..especially areas like Al-Soudah,Al-Habalah and Al-Faraa..

Al-Baha city , Al-Nammas and the areas between them are beautiful too.

you can take a road trip because all of them are on the same road with about 600 km long starting from Al-Taif city..
