District 7 of Ho Chi Minh City (HCMC) is one of the few districts surrounded by large rivers and canals. District 7 is at the intersection between two large rivers, Saigon River and Dong Nai River, and is a transitional place between the city centre and the surrounding districts (Nha Be District and Binh Chanh District). With a special location, District 7 is faced widespread urban flooding caused by both rain and tides, being extra transitional factors in population density and economic conditions. With the infrastructure for water drainage and anti-tide being still incomplete, the impacts of flooding have caused many disadvantages to people living in the area. Inheriting the studying on economic damage caused by flooding of Ho Chi Minh City in the period 2016 -2019, the topic of surveying and assessing economic damage caused by flood of people living in District 7 for the period 2021 - 2022 is performed. The results of the study showed that the distribution of inundation, damage level and risk of damage due to flooding are concentrated in the densely populated areas and riverside areas. Thereby, the study wishes to contribute a "way" to assess the damage caused by flooding for the management agencies of the district as well as Ho Chi Minh City.Quận 7 của Thành phố Hồ Chí Minh (TP.HCM) là một trong số ít quận được bao quanh bởi các con sông và kênh rạch lớn.
