HEAVY RAINS AND FLOODING IN CITIES

Urban flooding, caused by rising river levels as a result of heavy rainfall or heavy snowmelt, is common throughout the world. In the conditions of the cities of Uzbekistan (Tashkent, Samarkand, Bukhara), located on the hilly terrain of arid zones, flash floods and inundations occur as a result of anthropogenic changes in the urban landscape and surface coating properties. Thus, the development of urban infrastructure leads to an increased risk of flooding as a result of heavy rainfall. The paper outlines methods for constructing a digital model of the city's relief and a mathematical model of water flow along the relief of the urban area. Changing the topography through the construction of roads and structures leads to the formation of flood zones.
