黄河山东段河道迎来涨水过程，山东做好调水调沙期间黄河防汛工作

Core Points - The Yellow River's water diversion and sediment transport project is currently underway, with significant water flow entering Shandong province, indicating a proactive approach to manage water resources and mitigate drought conditions [1][2]. Group 1: Water Management and Flood Control - The Yellow River will officially enter its main flood season on July 1, necessitating the reduction of water levels in relevant reservoirs to ensure flood control capacity [2]. - The Yellow River Water Resources Commission has initiated a coordinated operation of multiple reservoirs to manage water flow effectively, with maximum discharge from the Xiaolangdi Reservoir expected to reach approximately 4,600 cubic meters per second [2]. - The ongoing water diversion and sediment transport project is characterized by high flow rates and extended duration, which may alter river dynamics and pose risks to river engineering structures in Shandong [2][3]. Group 2: Preparedness and Monitoring - The Shandong Yellow River Administration has revised and implemented water diversion and sediment transport plans, conducting over 40 flood prevention drills and identifying 134 key defense points [3]. - Continuous monitoring is being conducted using nearly 3,000 video surveillance units and over 220 drones to ensure early detection and response to potential flood risks [3]. - The administration is also preparing flood control materials, including 1.33 million cubic meters of stone and 28,300 tons of hemp rope, to ensure readiness during the water diversion process [3].
