Ho Chi Minh City is a low-elevation coastal city with and rapidly increasing population. Thu Duc, the city in Ho Chi Minh City, is the first city in Vietnam that belongs to the type of city administrative unit directly under the central city. This area is greatly affected by flooding, classified into three groups: heavy precipitation, tidal current, and combined tidal current and heavy precipitation. In this study, the flooding situation caused by the groups in the planning period (from 2010 to 2020) will be assessed and mapped by using GIS. The results show that, in the period from 2016 to 2021, flooding by heavy precipitation was more serious than that by tidal current. Compared to the drainage planning map in District 2, District 9, and Thu Duc District by 2020, some flooded locations due to no drainage system, lack of drainage systems, and unresponsive drainage systems have not yet been planned. In District 2 and District 9, some locations experienced flooding attributed to heavy precipitation, yet there is currently no drainage plan in place until 2020. In Thu Duc district, the majority of flooding incidents caused by precipitation can be attributed to the degradation of the existing drainage system, compounded by the absence of a sewer system. Furthermore, there were more points of re-flooding and more severe flooding compared to the same time in the previous period. This research is the scientific basis for flood control planning for the city as well as socioeconomic planning.
