The low-lying terrain in downstream area of Sai Gon - Dong Nai river is mostly affected by natural disasters such as flooding, saltwater intrusion causing difficulties in process of socio-economic development. The project of building Vung Tau - Go Cong sea dyke with a length of 32 km was proposed to solve these problems, particularly creating a reservoir for storing water and preventing saltwater intrusion, expanding urban space, industrial parks, tourism, services, shelter for boats from the storm, reserving fresh water in the future.

In urban areas, flooding can be very serious due to high population density and important infrastructure. As rainfall data at high temporal and spatial resolutions are required as input for urban flooding forecast, in this study, the Weather Research and Forecasting model (WRF) with four nests, two-way interaction is used to simulate the heavy rainfall event in Hanoi from 30/10/2008 - 01/11/2008 to investigate model ability on generating rainfall data on high temporal and spatial resolutions.

In this research, the numerical model MIKE URBAN is used to simulate the rainfall-runoff, routing and surcharge processes in Yen Hoa - Hoa Bang areas. Water depth and flood durations are indicators to assess the performance of the proposed solutions. The result of this research indicates that the renovation of the drainage system, i.e. enlargement in conduits’ diameter, can reduce inundation time significantly

Viet Nam is among the nations most severely affected by climate change. In a recent effort to respond to the adverse effects of climate change on urban flooding, the Technical Support Unit (TSU), ENABLE-Belgian Development Agency, the Viet Nam Institute of Meteorology, Hydrology and Climate Change, and other institutes have studied the impacts of climate change on urban flooding in the provinces of Ha Tinh, Ninh Thuan, and Binh Thuan.
