Abstract
Introduction. The lower Sai Gon – Dong Nai area in general and Ho Chi Minh City in particular is a major economic and financial centre of Viet Nam, but faces many pressing problems, of which the unresolved are housing shortages and flooding. This paper presents the results of a study of flooding in the lower reaches of the rivers Sai Gon – Dong Nai.
Materials and methods. This study uses the MIKE 11, MIKE 21 and MIKE FLOOD models to estimate the area and depth of flooding with and without flood control structures, providing a benchmark for each building and flood zone.
Results. The calculation results showed that the commissioning of flood control structures will help protect the central areas of the city from flooding, the flood area will decrease, while the flooding of external areas during the operation of hydraulic structures increases.
Conclusions. Calculating the depth for each flood zone and establishing reference-building elevations necessary for spatial planning can provide scientific input to the Ho Chi Minh City planning and construction management authorities in developing measures to minimize flood damage in the near future.
