  author={Sheng Long Yang and Jinhan Zhang and Jun Zhu and Shixun Dai and Ang Gao},
[1] On the basis of estimates of sediment accumulation in reservoirs, the impact of 50,000 dams on sediment supply and intertidal wetland response in the Yangtze River catchment is examined. The total storage capacity of reservoirs is 200 10 m, or 22% of the Yangtze annual runoff. The sediment accumulation rate in reservoirs has increased from 0 in 1950 to >850 10 t/yr in 2003. Although sediment yield has increased with broader soil erosion in the river basin, the total riverine sediment… CONTINUE READING
