三维水沙输移模型对深圳深水湾水沙输移的研究

Study on 3D numerical modeling of suspended sediment transport in the deep bay,Shenzhen

运用三维水沙输移模型研究深圳深水湾的泥沙输移,经过实测资料的验证,计算值能够模拟实际情况,表明波浪对泥沙输移有重要的影响。为进一步研究深圳深水湾泥沙在潮流作用下的输移规律,模拟了1998年7月21日至1998年8月21日涨退潮期间的水沙运动,计算结果表明深水湾属于泥沙淤积区域。

A 3D numerical model was used to study sediment transport in the deep bay. The results showed the model can reasonably simulate the tide elevation, sediment concentration and velocity. The wave had a great effect on sediment concentration. The simulation was conducted for the period from June 21, 1998 to July 20, 1998 during flood-ebb tidal period. The simulation results showed that the deep bay is under deposition state.
