| 摘要: |
| 泥沙淤积不仅影响水库库容，其中大量污染物还会影响水库水质。运用MIKE21软件对汤浦水库泥沙分布进行模拟研究。结果表明：泥沙在库区分布不均，河流入库位置淤积较少，局部甚至有冲刷；库区中部是泥沙淤积主要地带，模拟最大淤积厚度约30 cm；坝前位置淤积最小，厚度约为12 cm。模拟结果与沉积物淤积厚度采样结果一致，说明该模型能合理模拟汤浦水库沉积物分布状况。模型提供的沉积物分布状况对控制汤浦水库内源污染有一定参考价值。 |

| Abstract: |
| Sediment deposition not only occupies the storage capacity, but also releases pollutants into the water body. In this study, the sediment distribution in the Tangpu reservoir has been investigated based on MIKE 21 software. The research results show that the sediment distribution is uneven in the reservoir. At the zone of the reservoir entrance, sediment deposition is not severe, and sediment erosion even occurs at sone places. In the centre of the reservoir there is significant sediments deposition, and the maximum simulated thickness of sediment deposition is about 30 cm, and the minimum thickness is about 12 cm, which is close to that of the dam front. Sediment sampling results are consistent with the simulation results. It means that the model can be used to simulate the sediment distribution along the Tangpu reservoir reasonably. The simulation results have some reference values for the control of internal source pollution in the Tangpu reservoir. |
