摘要
在桑沟湾汁算潮流场基础上,采用ADI法,建立了拉格朗日余流模型和平流——扩散输运模型。对排污口的污水输运轨迹进行了跟踪,并预测了桑沟湾1995年、2000年的水质,绐出了COD浓度分布的发展趋势,指出桑沟湾是一个水交换滞缓、物理自净能力较弱的海区。据此可为桑沟湾沿岸的排污口选址提供依据。
Based on the computed tidal current field of Sanggou Bay, this paper applies the ADI method to constructing the model of Lagrangian residual current and advection-dispersion transport , and tracks the transport of sewage discharged, and predicts the water quality for the years 1995 and 2000, and gives the change tendency of COD. It is pointed out that the physical self-purification capability and water exchange of Sanggou Bay are weak. A basis for selection of pollution discharge positions is provided.
