According to typical water and sediment processes, we calculated the joint desilting scheduling of Xiluodu, Xiangjiaba and Three Gorges cascade reservoirs in two modes, respectively: sediment peak regulation mode, and dynamic mode of “storing clear water and releasing muddy water” in flood season. Results revealed that the scheduling of cascade reservoirs in sediment peak regulation mode could improve, to a limited extent, the outbound sediment discharge of cascade reservoirs in qualitative sense; the dynamic mode of “storing clear water and releasing muddy water” in flood season is conducive to improving the outbound sediment discharge to a large extent. Furthermore, we proposed corresponding joint desilting schemes in sediment peak regulation mode and dynamic mode of “storing clear water and releasing muddy water” in flood season for Xiluodu, Xiangjiaba and Three Gorges cascade reservoirs.
