Geography and hydrology of Jeddah

The city of Jeddah is situated on the Red Sea coast, beneath the northern escarpment of the Red Sea Rift known as the Jabal al Hejaz, which reaches {{convert|600|to|1000|m|ft}} in the region. The population of the city is about 3.4 million (2009 estimate) in an urban area of {{convert|1765|km2|sqmi|abbr=on}}, giving a population density of {{convert|1900|PD/km2|PD/sqmi}}. The climate is arid, with most rainfall occurring between November and January, usually as thunderstorms.{{citation|title=Geographical Location and Climate|url=http://www.jeddah.gov.sa/english/jeddah/weather.php|publisher=Jeddah Municipality|accessdate=27 November 2009|archive-url=https://web.archive.org/web/20090915003134/http://www.jeddah.gov.sa/English/jeddah/weather.php|archive-date=15 September 2009|url-status=dead}}

At least eleven wadis converge on the city, and localised flooding is common after rain. The municipality is currently investing 1 billion riyals (US$270 million) in storm drains, but the cost of a full system is estimated at an additional 3 billion riyals (US$800 million).{{citation|title=SR3 billion needed for proper drainage: Official|url=http://www.saudigazette.com.sa/index.cfm?method=home.regcon&contentID=2009112755617|author=Abdulaziz Ghazzawi|newspaper=Saudi Gazette|date=27 November 2009|accessdate=27 November 2009|archive-url=https://web.archive.org/web/20120302075745/http://www.saudigazette.com.sa/index.cfm?method=home.regcon&contentID=2009112755617|archive-date=2 March 2012|url-status=dead}} In November 2009, only some 30% of the city was protected against flash flooding and then, often with only one-inch (25-millimetre) pipes.

2009 Hajj pilgrimage

25 November was the first day of the annual four-day Hajj pilgrimage to Islamic holy sites in and around Mecca, for which Jeddah is the main entry point for foreign pilgrims arriving by air or sea. The number of foreigners, as well as Saudi citizens,{{Cite news|title=Heavy rain and swine flu fears hamper Hajj|url=http://news.bbc.co.uk/2/hi/middle_east/8377818.stm|work=BBC News|date=25 November 2009|accessdate=27 November 2009}} was slightly lower than in previous years, possibly because of health fears due to the pandemic of H1N1 influenza. However, over 1.6 million are still believed to have made the hajj, with 200,000 coming from Indonesia alone.

According to the Saudi Interior Ministry, none of the flood victims were taking part in the pilgrimage. However, the main Haramain expressway between King Abdulaziz International Airport and Mecca was closed on 25 November, stranding thousands of pilgrims. Parts of the {{convert|80|km|mi|adj=on}} highway were reported to have caved in, and the Jamia bridge in eastern Jeddah partially collapsed. The highway remained closed on 26 November amid fears that the bridge would collapse completely.

Rain was unusually heavy in Mecca on 25 November, as well as in nearby Mina, where many pilgrims stay in vast tent cities. The weather had improved by 26 November, and pilgrims had to face "scorching heat" on the plain of Mount Arafat for the second day of the Hajj.{{citation|title=Bright weather greets pilgrims on Arafat|url=http://www.saudigazette.com.sa/index.cfm?method=home.regcon&contentID=2009112755616|newspaper=Saudi Gazette|date=27 November 2009|accessdate=27 November 2009|archive-url=https://web.archive.org/web/20120302080009/http://www.saudigazette.com.sa/index.cfm?method=home.regcon&contentID=2009112755616|archive-date=2 March 2012|url-status=dead}} Hassan Al-Bushra, an epidemiologist at the Cairo office of the World Health Organization, said "there is no evidence" that the rain would worsen the spread of the H1N1 flu virus, a view shared by the U.S. Centers for Disease Control and Prevention (CDC).
