Urbanization often comes with flooding problems. The objective and subjective reasons why this situation persists and becomes increasingly serious are climate change and the concretization process. Currently, many studies have proposed solutions to forecast and warn of rain and tide causing urban flooding or methods to reduce flooding with sustainable green buildings. However, these solutions are all built on the old urban foundation, so flooding continues and the effectiveness of flood reduction is not high. In this article, the authors research the new urban area of Nam Can Tho, Cai Rang district, Can Tho City. This area is in the process of planning for infrastructure construction, so initial solutions have been proposed. Preventing flood risks caused by uncontrolled and unsynchronized urbanization is extremely necessary.
