الملخص EN

Scientific research about Spatial anlysis for risk assement of foold on the easter side of the nile valley between om khait valley in the south and al dire valley in the north , The effects of the floods on the study area, and the classification of valleys in the study area according to the degrees of danger, then a geomorphological assessment of the dangers of the floods, then knowing the methods of treatment and methods of protection - Using modern methods and sensing systems in meteorological monitoring of clouds and weather phenomena, following up their movement and development, forecasting rainfall amounts and determining their locations within the basins and the location and quantity of flow to warn residents and road users of the danger of torrential rains.

- Establishing an early warning system to predict the occurrence of floods in order to save time to take emergency measures to reduce the risk of floods - Make of dams on the most dangerous valleys to impede the flow of water.

- Cladding the roads with sides higher than the level of the valleys’ stomachs by using layers of water-resistant reinforced cement instead of rubble, which proved to be unsuccessful in facing torrential rains.

- Building large structures that meet the areas of intersection of roads with watercourses at appropriate heights and that have openings under bridges for the passage of water under them.

- Cleaning and packing the flood drains so that they do not overflow on the sides in the event of torrential rains, as happened at the exit of Wadi al-Sabil or the so-called salaah
