【 摘 要 】

Areas suffering from storm water drains are considered to be the places most at risk, water torrents have an effect on urban areas and can cause a lot of damage to buildings and infrastructure. Moreover, there is dangerous situation whereby urban growth is occuring towards at-risk areas. The urban growth rate in risk areas rose up to 24.9% in 2001, and reached 48.8% in 2013. Urban growth in "Abouelreesh" village had been influenced by the construction of larger buildings, because most people were looking forward to live in bigger houses. We can discover the previous problem by observing the average size increase of the buildings' areas from 2001 until 2013, especially in risky areas where the average building's area had grown from 254 m2 in 2001 to 411 m2 in 2013. This Phenomenon is considered to be very important factor which attracts the urban growth towards the risky areas in spite of the danger surrounding them.
