MATHEMATICAL MODEL OF FLOODING IN THE CITY UNDER STRONG RAIN PRETICIPATIONS

Abstract

The article provides an analysis of flooding of urban areas on the basis of a hydrological model for the formation of a slope runoff. the hydrological model is based on theoretical studies and materials of observations of landscape changes of anthropogenic characters. due to changes in the infrastructure of urban areas and the increase in the area of surface coverage with asphalt concrete and impermeable materials, the rate of water filtration into the soil decreases and the speed of slope runoff increases. these anthropogenic changes lead to a sharp increase in the water level in the depressions and remain as the main cause of the flooding of the territories, especially during heavy rains and the risk of emergency situations. the number of weather anomalies in the form of heavy rains increases due to global climate change, which in turn causes the risk of emergency situations in the cities of Uzbekistan.
