Application of GIS and SWMM model to assess urban flooding in Metro Residential Area of Ninh Kieu District

Abstract

Ninh Kieu District is an urban district with a rapid urbanization rate and a complex dimension. This factor has made urban flooding in this district very serious. Metro Residential Area is one of the areas currently being strongly affected by urban flooding in Ninh Kieu District. This research is conducted to apply GIS and SWMM model to assess urban flooding in Metro Residential Area. GIS is used to digitize the drainage system, while SWMM model is used to simulate urban flooding in the study area. Research results have shown the flood level, flood time, flood volume, flow velocity and frequently flooded locations in Metro Residential Area. This is an important basis for the development of solutions to reduce flooding, thereby reducing the impact of urban flooding and improving the quality of life of the residential community living in the study area.
