Evaluation of the Impact of Urban Green Space on the Climate in the Flood Event in Sarab Shahabad, Khorramabad

Urban development with the current methods has had many negative effects on water resources and urban ecology and has caused urban environments to distance themselves from the goals of sustainable development. In the field of hydrology, studies show that rainwater management in cities in the traditional way has had negative effects, including an increase in the volume of runoff and an increase in peak flows. Also, the traditional methods of urban water management by removing native vegetation and increasing hard levels have greatly reduced the urban green space per capita. Considering the climate changes as well as the damage and losses caused by floods in recent years, as well as the reduction of vegetation around urban springs, and the increase in life and financial risks for citizens, in this research the risk of flooding and the zoning of flood-prone lands in The source of Sarab Shahabad, Khorramabad city It was done using satellite photos and Arc GIS software. For prioritizing the criteria, the AHP model was used. And the Expert Choice software environment was used, which ultimately resulted in the conclusion that the most important factor in the occurrence of floods is the lack of vegetation in the area and the distance from the bed of the source and construction on the way to the source, which causes irreparable damage to the area and It has also become a city.
