摘要
基于风浪和水流计算模型,综合考虑风浪作用的影响,建立了计算酸性污染物的输移扩散模型。通过计算三门湾海域在常浪向情况下四个时刻的污染物排放模式,将有无风浪影响的两者结果进行对比,初步分析了风浪作用下的酸性污染物扩散规律。结果认为:潮型、排放时刻、风浪等因素都会使酸性污染物的扩散面积与污染持续时间发生变化;并且在该方向风浪影响下,扩散面积与污染持续时间都有减小的趋势。
Based on the swan wave model and tidal current model, the transport model of the acid pollutants affected by wind wave was discussed. Under normal-wave direction NE ,several projects in spring tide and neap tide in Sanmen coastal area were simulated and results were compared with one without waves. It showed that the diffusion area and duration of pollution could be affected by the hydrodynamic condition, discharged time of acid pollutants and wind wave, etc. Both of them showed the decreasing trend under the normal-wave direction in Sanmen coastal area.
