Preliminary Discussion on Scheduling Index of Warping Tests in Xiaobeiganliu of the Yellow River

In this paper, according to warping practice of warping tests in Xiaobeiganliu of the Yellow River during 2004 and 2006, the specific goal and the main scheduling index are put forward for realizing the warping area's purpose of depositing coarse sand and discharging the fine. The specific goal is the depositing proportion of the coarse sand about 80%, the fine sand not less than 50%. The main scheduling target is, the proportion of the sediment concentration discharging and introducing about 0.5 in the warping area, the proportion of the sediment concentration discharging and introducing of the coarse sand about 0.25, the coarse sand proportion of drainage about 8%, the proportion of the sediment concentration discharging and introducing of the fine sand not less than 0.43, and The ratio of the coarse sand proportion between drainage and diverting water about 0.5.
