Management of drainage network on Southern bank of Huong River in Hue City in the context of climate change

Tóm tắt

This paper aims at proposing solutions to enhance efficiency ofthe drainage network onthe Southern bank of Huong River in Hue City in the context of climate change. Southern bank of Huong River area has an elevation of 2 to 4 meters, but in severallocations, the elevation is very low, only 0.5m. After heavy rains, some locations are flooded for several days. Under the impacts of climate change,unseasonal rains with high intensity have caused inundation for wards of Vy Da, Xuan Phu, Vinh Ninh, Phu Nhuan, An Cuu, Phuong Duc, etc.,affecting the people’s lives and local infrastructures. Currently, the drainage network on the Southern bank of Huong River area has been invested with the new construction of sewers, interceptors, overflow chambers,etc., however, the flooding situation has not been solved. From the analysis results, the paper offers some solutions to improve the drainage network capacity as well as to enhance the City’s resilience in the context of climate change, including consideration of additional design parameters, technological management and use of sustainableurban drainage solutions (SUDSs) for the City.
