The realm of Saudi Arabia is characterized climatically as a semi-parched area as per the “world guide of Köppen–Geiger environment grouping.” These environments will, in general, be sweltering, now and again incredibly blistering during summers and gentle to warm winters.

Jeddah territory is portrayed by various watercourses that run into the shallow seaside waters, which conveys adequate suspended sand and mud to store enormous inshore covers of delicate silt. These seepage frameworks have taken apart the Jeddah region and are described by high angles.

11 years prior, 2 days before Eid-ul-Adha, my family and I were going to Jeddah, which is about 700 km away from my city Khamis Mushayt and right around 100 km away from Mecca city. We were on an expressway 300 km away from Jeddah when we became more acquainted. It is pouring vigorously in Jeddah, which was the heaviest precipitation in Saudi Arabia in 10 years. 70mm downpour fell in Jeddah in 4 to 5 hours. Around then, there were no such game plans to manage a particularly regular catastrophe since it scarcely downpours Jeddah and is considered as one of the most blazing cities in Saudi Arabia.

When we entered the city, the Hajis were gliding out and about; because the streets were hindered, every one of the underpasses was loaded up with water.

For the most part, individuals in Gulf nations purchased their sheep/cow/goat 1 or 2 days before the Holy Sacrifice or at the hour of penance. As it is stringently illegal to butcher creatures at home, individuals need to take them to butcher house, where the specialists butcher them with no wreck; the same happened that year. Thus, individuals purchased their creatures which at last passed on because they can’t swim as the water was standing 3 to 4 feet on the principal streets. Dead creatures were drifting on the water though some were sinking after a hard battle to live.

Many harmed highlights were recorded and archived due to the glimmer flood occasion. Profound channels were framed along the roads in certain spaces, which prompted the development of new stream ways straightforwardly in the city of settlements. Some new settlement houses were overflowed, and the water rose to fill the first and cellar floors. These blaze flood occasions had caused numerous disintegration highlights along the streets disintegration highlights to arrive at 4 m profundity where fine dregs were taken out totally.

25 November was the primary day of the yearly four-day Hajj journey to Islamic heavenly destinations in and around Mecca. Jeddah is the fundamental section point for unfamiliar explorers showing up via air or ocean. Just as Saudi residents, the number of outsiders was marginally lower than in earlier years due to well-being fears because of the pandemic of H1N1 flu. Notwithstanding, over 1.6 million are as yet accepted to have made the hajj. As per the Saudi Interior Ministry, none of the flood casualties were partaking in the journey. Notwithstanding, the primary Haramain turnpike between King Abdulaziz International Airport and Mecca was shut on 25 November, abandoning many pioneers. Portions of the 80-kilometer expressway were accounted for to have collapsed, and a scaffold in eastern Jeddah mostly imploded. The interstate stayed shut on 26 November in the midst of fears that the extension would fall totally.

At any rate, eleven aqueducts meet in the city, and limited flooding is normal after the downpour. The district is at present contributing 1 billion riyals (US$270 million) in storm channels, yet the expense of a full framework is assessed at an extra 3 billion riyals (US$800 million). In November 2009, just some 30% of the city was secured against streak flooding.

This is clear from the continuous event of cataclysmic event occasions and concentrated precipitation over various district pieces. As indicated by the field examinations, the level of effect is discovered to be high. The glimmer flood occasions in Jeddah city might be considered the main common risk occasions throughout the entire existence of the Jeddah district. The rainfalls in Jeddah city are either regular in the summer or front-facing types in the winter season.
