Xiaolangdi scouring and silting time

Before the Yellow River flood season comes every year, the Xiaolangdi will be washed by water and sediment. Generally between June 20th and July 10. Turbid flow containing a lot of sediment is washed away from the sand discharge hole, and the storage capacity is reserved for flood control.

Rushing through is a complex scientific dispatching project, which is affected by many factors such as flood, weather and the overall water situation of the Yellow River. Time is uncertain, it may stop at any time, or it may continue to form a landscape. Water and sediment regulation is the most spectacular moment at Xiaolangdi. During the period of water and sediment regulation, yellow and white rapids spewed out of the cave, such as Huanglong soaring, Qinglong falling from the sky, fighting down, setting off rows of huge waves roaring straight at the lower reaches of the Yellow River.
