Shanghai Chemical Industry Park (SCIP) is located at the north bank of Hangzhou Bay. Based on the measured data for the domain of SCIP,the characteristics and the influencing factors of the hydrodynamic conditions and sediment transport were studied. Considering coast defense of SCIP,one issue of the present work was focused on the effects of the dike construction on the beach protection. With the measurements of hydrodynamics and beach evolution during typhoon, several characteristics of the beach evolution were analyzed in case of the biggest natural disaster. Several standpoints about the inspection of the hydrodynamics and beach evolution in the domain were presented,referring to the evolution of deeper channel and the change of 0 m isobath.%通过分析历史资料,研究了杭州湾北岸上海市化学工业区堤防前沿的水动力特征、岸滩的冲淤演变特征及部分可能影响因素.针对化工区海防安全的要求,着重分析了堤防工程的若干工程效应及其对该水域岸滩保护的工程作用.针对该水域的最大海洋自然灾害-台风浪,汇总了工程建设前后几次强台风过境该水域时的若干水动力条件及岸滩损坏情况,分析了若干动力特征及岸滩冲淤演变的时空特征.通过资料分析,提出了针对杭州湾北岸上海市化学工业区海防安全所需重点关注的几点问题,包括前沿水域深槽演变的不断观测,近岸0m等深线变化的观测等.
