To keep the dams functioning, excess sediment has to be removed -- as seen in this photo of the Xiaolangdi Dam undergoing a sediment cleaning process. Many areas of China have already suffered flood damage, and there is no sign that the situation may improve: China's state weather bureau has forecast continued rain with the approaching typhoon season.
