The Xiaolangdi Multipurpose Project in the People’ s Republic of China is located on the yellow River in Henan Province. The main purposes of the dam are sediment management and better flood protection for more than 100 million people living downstream. The Y ellow R iver owes its name to its high sediment content. Downstream, sedimentation causes an annual 10 cm rise of the river bed so that the dikes along the 800 km long lower reaches have to be constantly in- creased in height in order to ensure flood protection. With the construc- tion of the dam, downstream sedimentation will be stopped for approx- imately 20 – 30 years. Afterwards, the sediment will regularly be flushed out of the reservoir and further on in- to the Yellow Sea. Other benefits to be achieved are power generation (6 x 300 MW) and water supply for irrigation of 2 million hectares of farm- land. CHINA Xiaolangdi Dam Rockfill dam
