Spatial and Temporal Variations of the Low Flow Stage in the Immediate Downstream Reach of the Three Georges Dam

The process of channel incision and low flow stages lowering along the Yichang to Jiangkou reach,which is at the immediate downstream of the Three Georges Dam,was investigated using statistical analysis of both stages data from more than ten gauges along the river and yearly channel topography observation data in the reach. The integrated effects of environmental factors such as geology,geomorphology,bed material and previous anthropogenic influence were examined with data analysis and numerical simulations. The analyses showed that channel adjustments are complex responses to the sharply reduction of suspended load in the special geology and alluvial environment. The pattern and rate of channel adjustment exhibits obvious spatial and temporal variations. As consequences,the stage lowering rate in upstream reach of Yidu had undergone a significant increase after 2008 because the roughness increment during bed armoring had come to a quasi-equilibrium state. Because the channel is scoured with the manners of deepening and widening respectively in the upstream and downstream of Zhicheng,the magnitude of stage lowering got a maximum in the vicinity of Yidu and a minimum in the vicinity of Zhicheng to Chenerkou. The differences in channel incision have also resulted in different adjustment of stage-discharge relations in the upstream and downstream of Zhicheng.The spatial and temporal differences of stage lowering should be recognized as an intrinsic property of the channel,and the recognition of this property will be helpful to evolutionary trend estimation and river management strategies development.
