The maximum flow rate of the garden station is about 4000 cubic meters per second. 18 pontoon bridges in the Ji'nan reach have been dismantled for 1 repairs, and the remaining floating bridges will be demolished from 21 days.
the relevant person in charge of the Yellow River River Bureau of Ji'nan City, the Yellow River Xiaolangdi Dam began to regulate water and sediment 19 days ago. According to the monitoring, at 14:00 on the 19 th, the water volume of the Ji'nan section of the Yellow River is 1900 cubic meters per second. In the Yellow River, the large water conservancy hubs make use of the huge water flow in the flood season. Through the impact on the silt of the river bed, the dam is discharged into the river, and then into the sea, reducing the deposition of the reservoir and the river bed, and increasing the flood capacity of the main channel. The main purpose of water and sediment regulation is to reserve storage capacity for flood control. The flood season in the Yellow River is generally in 7 and August, and water and sediment regulation is generally in June.
