How to utilize the joint operation of reservoir groups to maximize sediment discharge efficiency is a key technical challenge in water and sediment regulation.This paper selected the joint operation of Sanmenxia and Xiaolangdi reservoirs in the period of water and sediment regulation in 2023 as the object,analyzed the water and sediment processes of the two reservoirs under different matching opportunities and matching water levels,and quantified the water and sediment regulation effect under different matching opportunities and matching water lev-els between the two reservoirs.Although the Sanmenxia Reservoir has a smaller water storage capacity and limited water transfer capacity,by changing the discharge time of the reservoir,the scouring effect of Xiaolangdi Reservoir is quite different.As the matching water level decrea-ses,the amount of erosion in the reservoir area gradually increases.With the delay of the relative discharge time of Sanmenxia Reservoir,the erosion amount in the reservoir area shows a trend of first increasing and then decreasing.
