Zhenshui is the biggest tributary of Xiaolangdi Reservoir and its original storage capacity is 1.767 billion m3. By October 2010, the amount of sediment in Zhenshui reached 0.1691 billion m3, and the sand bar at Zhenshui estuary was 7 m in height. Influenced by operational mode of reservoir and terrain, the formation of sand bar has certain inevitabilities. The sand bar can prevent water and sediment exchange between mainstream and tributary, and the internal storage capacity of tributary is not effectively used. The experimental result shows that during the later sediment retaining period, some small reservoirs can be built at the end of Zhenshui. By restoring water during the high water level in non-flood season in these small reservoirs and discharging flow during the low water level in flood season to scour sand bar, the tributary and main channel in Xiaolangdi Reservoir can be linked up in long term, service efficiency and life of tributary storage can be increased.
