Abstract
A flood control project system composed of the Xinfengjiang Reservoir,Fengshuba Reservoir,Baipenzhu Reservoir,and mainstem levees has been established in the Dongjiang River basin,with its flood control capacity improving year by year.However,due to the impacts of global climate change,rainstorms and floods in the basin have become increasingly sudden,extreme,and abnormal,with disasters that break historical records and challenge conventional understanding occurring frequently.Flood control in the Dongjiang River basin still faces several challenges:in terms of flood control project construction,the potential of the flood control system has not been fully tapped due to constraints such as temporary inundation in the three major reservoir areas and uneven riverbed incision along the mainstem;in terms of flood regulation,there is a lack of precise technological support;in terms of unified basin-wide scheduling,some management mechanisms for water projects remain to be improved.In response to these issues,this paper proposes countermeasures from three aspects:strengthening integrated basin governance and unlocking the potential of flood control projects;improving forecasting accuracy and enhancing intelligent dispatching support;and unifying dispatch management and improving related mechanisms.These strategies are intended to provide a reference for gradually enhancing flood control capacity in the Dongjiang River basin and meeting flood control demands under extreme weather conditions.关键词
