摘　　要：研究近海海域水流、悬沙运动规律,运用基于COHERENS发展的水动力悬沙模型COHERENS-SED,结合当地一般波浪条件,模拟了青岛近海悬浮泥沙输运情况,并验证及分析了水动力环境及悬沙输运的模拟结果。结果表明:在波流联合作用下,近岸掀沙明显,大潮期间该海域近岸悬沙浓度值最高可达50 mg/L。Based on COHERENS, a three dimensional suspended sediment model COHERENS-SED is setup, combined with local wave conditions, to perform the simulation of three dimensional current and suspended sediment in the offshore zone of Qingdao. Then the results for the hydrodynamical environment and suspended sediment over this region are analyzed. The results show that under the combined action of waves and currents, the offshore resuspension is obvious, and the suspended sediment concentration is up to 50 mg/L during spring tide.
