Researchers’ Work from Yellow River Institute of Hydraulic Research Focuses on Flood Risk Management (Cumulative Sedimentation Hazard Map of Urban Areas Subject To Hyperconcentrated Flash Flood: a Case Study of Suide County In the Wuding River …): Risk Management – Flood Risk Management

2024 JUN 04 (NewsRx) -- By a News Reporter-Staff News Editor at Insurance Daily News -- Investigators publish new report on Risk Management - Flood Risk Management. According to news originating from Zhengzhou, People’s Republic of China, by NewsRx correspondents, research stated, “Flash floods can carry substantial sediment, posing significant sedimentation hazards in hilly cities. The sedimentation hazard map can reproduce the sediment thickness and extent of an extreme events scenario, playing an important role in sediment risk management.”

Financial supporters for this research include the National Key Research and Development Program of China, National Natural Science Foundation of China (NSFC), National Key Research and Development Program of China, Special Foundation for Public-interest Institutes of China, Excellent Youth Foundation of He’nan Scientific Committee, Natural Science Foundation of Henan, Significant Science and Technology Project of Ministry of Water Resources.

Our news journalists obtained a quote from the research from the Yellow River Institute of Hydraulic Research, “However, current research primarily focuses on modeling the inundation area and depth of floods, while studying sedimentation hazard caused by flash floods in urban areas remains insufficient. This paper aims to address this gap by utilizing a numerical model that simulates hyperconcentrated flow in hilly urban areas using the two-dimensional hydro-sediment-morphological model to compile the cumulative sedimentation hazard map. The model, built upon the open-source TELEMAC-MASCARET framework, incorporates Zhang Hongwu’s formula to simulate sediment-carrying capacity, particularly suitable for hyper-sediment concentration near the riverbed. This paper uses the data of extreme flash flood events in the Wuding River basin in 2017 to simulate and compile the cumulative sedimentation hazard map. The hazard map delineates the sedimentation hazard extent and level attributable to overbank floodplain sedimentation. Notably, the sediment thickness is highest in areas near the levees on both sides of the Dali River.”

According to the news editors, the research concluded: “Moreover, the map illustrates the extent of channel erosion resulting from hyperconcentrated floods, which could jeopardize bank stability.”
