On June 29, the Yellow River Institute dispatched two field workgroups to track and observe the water diversion and sediment transport process, focusing on the water level at the main channel and bank edges downstream of the Huanghe River below Gaocun, verifying the flow capacity of the downstream river channel.
The workgroups utilized RTK, drones, GPS, and water gauges to systematically observe the water level performance at sections with lower flow capacity on both banks of the Huanghe River below Gaocun, as well as the water height at the bank edges. They also inspected whether there were any overbank flows in the main river channel and the conditions of the production embankments and levees. As of July 2, the monitoring work from Gaocun to Aishan on the Huanghe River has been completed.
This field tracking observation allows for precise calculations of the flow rate in the flat sections of the Huanghe River downstream during the water diversion and sediment transport process. It provides a decision-making basis for real-time scheduling of reservoir discharge and scientific management of water engineering during flood periods, thereby ensuring flood safety in the lower reaches of the Huanghe River.
