以河南省原阳县韩董庄引水渠以西7.1km堤河作为引黄淤滩试验区，首先进行了来水来沙分析、渠首闸分沙比估计、堤南干渠输沙能力分析、放淤引水量估算、退水条件分析，以及退水区泥沙落淤量估算.在以上分析结果的基础上，按照便于管理运用、尽量利用现有水利工程、退水不影响排涝等原则，确定放淤方案为：将季庄支渠扩大到流量15m3／s，单口门放淤．工程实施后可获得：改良土壤、增加耕地面积、减轻渠道淤积、确保黄河大堤安全、扩大灌溉面积等效益
Taking the 7.1km embankment west of Han Dongzhuang diversion canal in Yuanyang county of Henan Province as the pilot area for diverting yellow and silting beaches, the paper first analyzes the incoming water and sediment, estimates the sediment discharge ratio of the headrace gate, Water quantity estimation, backwater condition analysis and sediment siltation estimation in backwater area.Based on the above analysis results, according to the principle of easy management and utilization, making full use of existing water conservancy projects and drainage without affecting waterlogging, The program is: to expand the branch of quaternary Zhuang flow 15m3 / s, a single door siltation. After the project is implemented, it is available to improve the soil, increase the area of cultivated land, reduce the channel siltation, ensure the safety of the Yellow River embankment, and expand the irrigation area.
