摘　　要：用ADI方法模拟了海湾中的潮流场，计算了污水排入海湾时的浓度．结果表明，湾内流场呈往复流状态，与实际流动情况基本一致；湾顶的污水浓度大于湾口污水浓度，浓度值从湾顶向湾口方向逐渐减少；落潮时海内的污水浓度大于涨潮时的污水浓度．ADI method is employed for the simulating flow in the Bay. When the sewage is drained into the Bay, the concentration of the sewage is computed. The results show that the tide current in the Bay present a reciprocating current and a good agreement between the computed value and the actual flow is obtained. The concentration of the sewage at the Bay top is thicker than one at the Bay mouth and the concentration is reduced gradually from the Bay top to the Bay mouth. The concentration of the sewag in the bay on the ebbtide is thicker than one on the flood tide.
