Assessing and zoning economic damage risk of the inundation in Thu Duc city on the period 2021 - 2022

Thu Duc city, a sub-city under the administration of Ho Chi Minh City, was established in 2020 through the merging of three districts (Thu Duc District, District 2, and District 9). Thu Duc city has faced extensive urban flooding caused by rainfall and high tides. The impacts of urban flooding cause many adverse effects on people living in the area. To address these challenges, a survey was conducted focusing on flooding (7 parameters) and subsequent damages (17 components), both direct and indirect. This survey and assessment of the economic damage incurred by the residents of Thu Duc city covered the period from 2021 to 2022. The results of the study showed that the distribution of inundation, economic damage level and risk were concentrated in densely populated areas and riverside areas. Therefore, the study contributed valuable data and assessment results of damage caused by flooding for the urban management agencies of Thu Duc city.
