Description

[0002] After the Yellow River flows into Shaanxi, the amount of sediment carried increases significantly, especially during the spring peach blossom flood and summer flood season, the sediment content increases exponentially, and this is also the critical time for spring and summer farmland irrigation. The project water supply brings a large amount of sediment into the channel facilities. With the reduction of water flow classification and the decrease of flow rate, some sediment is precipitated, forming siltation accumulation, resulting in a reduction in the channel flow section, affecting the normal function and efficiency of the project facilities, especially after entering the irrigation system. The siltation phenomenon is prominent, and dredging structure is needed for dredging.
