Abstract

In order to study the comprehensive influence of incoming water and sand level and pre-dam water level on sediment siltation in the Three Gorges Reservoir under the condition of new water and sand, this paper studies the coupling relationship between sediment sediment and pre-dam water level in the Three Gorges Reservoir under the condition of new water and sand based on the measured data of the Three Gorges Reservoir from 2003 to 2017. The results show that the relationship between siltation and pre-dam water level is different at different time scales, and from the perspective of long-term time period (annual or flood period), the amount of siltation is positively correlated with the water level before the dam. Besides, during a short period of time (monthly) the siltation is negatively correlated with it, which does not conform to the law of “the water level in front of rises with an increasing siltation”, and the water level before the dam has little impact on it.
