厦门浔江海域污染扩散数值模拟

Numerical modelling of pollutant dispersion in Xunjiang waters, Xiamen

本文采用ADI活动边界潮流数值模型模拟了厦门浔江海域的潮流，计算的结果与实测数据比较吻合。文中用欧拉污染扩散数值模型计算了从同安、集美、五通口排出的污染物（COD）对浔江海域的影响，同时采用拉格朗目污染扩散数值模型研究在湾口、集美和在北部的湾顶污染物瞬时排放后的运移情况。

The tidal circulation regime is simulated with a movihg boundary ADI model in the Xun-jiang Bay. The model results are compared with field observations and show good agreementboth in water level and currents. The concentration field of pollutants (COD),which are dis-charged from Tongan, Jimei,Wutongkou, have been computated by an Eulerion numericaldispersion model. The transient transport processes of the pollutants,which are released atthe mouth, the head of the bay and at the navigational channel near Jimei Town,have beeninvestigated with a Lagrangian transport model.
