从减少黄河下游河道淤积，尤其是艾山以下河道淤积及充分利用黄河水资源的角度出发，对桃花峪水库与小浪底水库联合调水调沙运用进行了研究。结果表明：在小浪底水库下泄清水时，通过桃花峪水库调节引走清水，可减小进入下游的清水流量，使高村以上河段冲刷量减少，从而减少艾山─利津河段的淤积量；小浪底水库调沙库容越大，或桃花峪水库运用水位越高，对向华北地区供水及对下游减淤越有利；小浪底水库调沙库容越大，同样的运用方式下桃花峪水库库容损失越慢。
From the point of view of reducing siltation in the lower reaches of the Yellow River, especially siltation below the Ai River and making full use of the Yellow River water resources, a study was conducted on the combined water and sediment management of the Taohuayu Reservoir and Xiaolangdi Reservoir. The results show that when the Xiaolangdi reservoir discharges clear water, the water flow into the downstream reaches can be reduced by removing water from the Taohuayu Reservoir to reduce the amount of flushing over the upper reaches of the Gaomun River, thus reducing the sedimentation of the Aishan-Lijin Reach. The Xiaolangdi The larger the reservoir sediment storage capacity or the higher the water level of Taohuayu reservoir, the more favorable it is to supply water to North China and reduce the siltation downstream. The larger the sediment storage capacity of Xiaolangdi Reservoir, the slower the reservoir loss of Taohuayu Reservoir under the same application mode.
