Risk Assessment of Water Pollution Emergencies for Water Diversion Project Based on Cloud Model:A Case Study on Henan Section of the Yangtze River to Huaihe River Diversion Project
Risk Assessment of Water Pollution Emergencies for Water Diversion Project Based on Cloud Model:A Case Study on Henan Section of the Yangtze River to Huaihe River Diversion Project
Assessing the risks and reducing the hazard level of water pollution emergencies in water diversion pro-jects are of prominent significance to leveraging the benefits of such projects and enhancing regional water supply safety.The Drivers-Pressures-State-Impacts-Responses(DPSIR)model was employed to establish a risk evaluation index system that reflects the characteristics of risk sources and risk receptors.A method of evaluating the risk grades of water pollution emergencies was proposed by utilizing the cloud model to quantitatively assess the risk wa-ter pollution emergency in the Henan section of the Yangtze River to Huaihe River Diversion Project.Findings re-vealed low risks of water pollution emergency in the studied section.Specifically,the risks of two sections were classified as significant(Level Ⅱ),while five were designated as general(Level Ⅳ).These results aligned with qualitative evaluations considering risk source magnitude,risk receptor vulnerability,and risk control effectiveness.Our study offers a novel approach for assessing the risks of water pollution emergencies in water diversion projects and lays a foundation for risk management in the study area.
