Hydraulic and Hydrodynamic Research on Excavated Channel on the Yellow River Downstream

With the hydraulic and-hydrodynamic analysis on the Yellow River downstream excavated channel profiles, comparison of flood and sediment transport capacity analysis before and after the dredging demonstrate that: after dredging the river channel, under the specific water stage, the flood transport capacity was increased, however, the sediment transport capacity was decreased, the river channel will be back deposition. Under the same cross-section dredging area conditions, the narrow and deep channel have more utility than wide and shallow channel for mitigating deposition. The hydrodynamic calculating result demonstrates that the hydraulic analysis efficient and hydraulic analysis set up the foundation of excavated profiles on the Yellow River downstream.
