Influence of the Three-Gorges Reservoir on Geomorphic Process on Bank Slope of the Yangtze River

After the completion of the Three Gorges reservoir,a series of changes in fluvial geomorphology process- es will inevitably occur on bank slope of the reservoir.Two parallel permanent fluctuating belts will form on bank slope,and thus the power of reservoir water will fluctuate with changed water level.Changes in groundwater and reservoir water may affect bank slope surface and rock medium.The changes have physical,chemical and mechan- ics effects on rock materials,and influence loose deposits and rocky bank slope,differently.The major geomorphic processes may shift from gravitational geomorphic processes to creep,slide,collapse,erosion and washing process- es,which transforms bank slope in turn.The geomorphic transformation and re-transformation processes on bank slope will last for a long time.
