Abstracts

Hoa Bang street is known as one of flooding hot spots in Hanoi with 30 inundated times during last 4 years. In 2019, a new conduit has been set up to drain the water from Hoa Bang street to To Lich River. However, the flooding situation has not been significant improved. Therefore, it is necessary to evaluate the capacity of the drainage systems as well as effectiveness of flooding mitigation measures. 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.
