Spatial modeling of flood risks in Wadi Umm Al Shababit in Salah al-Din Governorate - Al-Shirqat District using artificial intelligence

Abstract

layers with little permeability prevent water from draining and leaking into the ground. In addition to the climatic situation and topography of the basin between contour lines (170) and line (220) m, which played a prominent role in influencing the hydrological behavior of the watercourse and accelerating the force of water flow. Human factors also contributed to the exacerbation of the phenomenon of urban flooding, especially after the increase in population and urban expansion, which led to the transformation of agricultural lands into residential lands, which led to a reduction in seepage and losses and thus an increase in the amount of water in the valley stream, as agricultural areas consumed part of That water. In addition to this, there is a lack of planning in the process of designing hydrological facilities and bridges, and what is the carrying capacity that they accommodate, and not taking into account the water flow of the valley in extreme cases, in addition to the small number of model bridges, which are primitive and lack engineering specifications, as the residents built them.In addition to not irrigating the valley stream and spreading plants such as sedge reeds, in addition to constructing an earthen dam in the high areas north and west of Wadi Umm Al-Shababit, which was constructed according to non-technical specifications, as the intensity of the water flowing into the basin of that dam led to the breaking of parts of the earthen barrier, causing an increase in The amount of water coming from the western side.
