Xiaolangdi Water and Sediment Regulation Plan in 2023

The time of water and sediment regulation in Xiaolangdi is from June 19 to June 2 1 day.

Xiaolangdi Reservoir is one of the important reservoirs in the middle reaches of the Yellow River, and it is also an important base for water and sediment regulation in the Yellow River. This is the 22nd year that the Yellow River implements water and sediment regulation before flood season. This water and sediment regulation started at 2 1 and lasted about 20 days.

The Yellow River's water and sediment regulation is to use the reservoir's regulating capacity to artificially create "floods" to scour the river course, and to wash the sediment deposited in the reservoir and downstream river course into the sea, so as to alleviate the sediment deposition in the reservoir and downstream river course, reduce the sediment deposition in the reservoir and downstream river course, and prevent the riverbed from rising.

With the approach of the main flood season of the Yellow River, combined with the flood demand of reservoirs in the middle reaches of the Yellow River, the Yellow River Conservancy Commission of the Ministry of Water Resources, on the basis of reservoir impoundment and river inflow forecast before the flood season, combined with years of experience in water and sediment regulation,

Regulation of water and sediment is a complex scientific dispatching project. Affected by floods, weather, the overall water situation of the Yellow River and other factors, the time is uncertain. At the most spectacular moment of Xiaolangdi, during the adjustment of water and sediment, a yellow-white torrent spewed out of the cave.

Brief introduction of Xiaolangdi scenic spot:

Xiaolangdi water control project is a key project for harnessing and developing the Yellow River, which belongs to the national key project during the Eighth Five-Year Plan. The project was intercepted on 1997 and ended on 200 1. Xiaolangdi is located on the main stream of the Yellow River, 30 kilometers southwest of Jiyuan City, Henan Province. It is 30km away from Sanmenxia Reservoir130km away from Zhengzhou Huayuankou115km away. It is the only control project below Sanmenxia in the main stream of the Yellow River that can obtain large storage capacity.

Xiaolangdi Reservoir is located in the Shanxi-Henan Yellow River Gorge which passes through Zhongtiao Mountain and Wuwang Mountain. The total length of the reservoir area is1.30km, with a total area of 272km2. After the closure of Xiaolangdi Dam, more than 20 scenic spots, such as Xixia Lake, Dam Wetland Park, Zhang Ling Peninsula Resort, and the Three Gorges of the Yellow River in the Shanxi-Henan Yellow River Gorge, complement each other with the majestic reservoir dam.

The natural landscape of lakes, mountains, thousand islands and "high gorge flows out of Pinghu" has been formed, making Xiaolangdi Reservoir a large-scale tourist area composed of natural scenery and water conservancy projects.
