Sand-washing operation conducted in China’s Xiaolangdi Reservior.
Tourists watch water gushing out from the Xiaolangdi Reservoir on the Yellow River during a sand-washing operation in Luoyang, central China’s Henan Province, June 30, 2014. The on-going operation works by discharging water from the reservoir to clear up the sediment in the Yellow River, the country’s second-longest waterway. This year, the sand-washing operation will be jointly conducted in Xiaolangdi Reservior, Sanmenxia Reservior and Wanjiazhai Reservoir, an effort to make speeding currents carry tons of sand into the sea. The Yellow River has been plagued by an increasing amount of mud and sand. Each year, the river bed rises as silt deposits build up, slowing the water flow in the lower reaches. (Xinhua/Zhu Xiang)
