摘要
针对榕江的水沙运动特点,结合工程河段的航道整治工程,建立了适合该区域的二维水沙数学模型,模拟该区域的水沙运动情况,并采用实测资料进行了模型验证,所得计算结果与实测资料比较吻合。证明模型能较好地模拟受潮汐影响河道的水流泥沙运动情况,可为河道的整治提供技术支持。
Aiming at the movement characteristics of the flow and sediment in Rongjiang River and combining with the waterway regulation engineering, the two-dimensional mathematical model which simulates the movement characteristics of the flow and sediment in this area is established. The field measurement data are adopted to verify the correctness of the model, and the simulation result is closely fitted with the field data, which shows that the model is creditable to simulate the movement situation of water and sediment in tidal river. Therefore, it can provide the technical support for the waterway regulation.
