Assessing the Effects of Urbanization on Water Flow and Flood Events Using the HEC-HMS Model in the Wirynka River Catchment, Poland

Floods are among the most devastating natural disasters in small urban watersheds resulting loss of life and enormous damage to property posing a serious threat economy. Appropriate modeling can be useful tool prevent reduce such flood risks. It is currently important use hydrological models assess predict water availability river basins due climate change develop strategy cope with changing environment. The study used an integrated approach combining geographic information system (GIS) impact urbanization on flash floods peri-urban developing areas. was carried out for two spatial aspects relating 1990 2018. model allowed simulation flow that occur under different rainfall probabilities. showed rapid adversely affects processes. Reduced infiltration capacity increases runoff, thereby increasing risk flooding or waterlogging. Therefore, it extremely properly manage rainwater area.
