Performance Analysis and Prediction of Beach Nourishment Project in Zhongzhi 6th and 9th Bathing Places in Beidaihe

Abstract:

In order to meet the using demand of Zhongzhi 6th and 9th bathing places in 2008’s summer, a project of beach nourishment with submerged breakwater is carried out by Qinhuangdao Mineral Resource and Hydrogeological Brigade, Hebei Geological Prospecting Bureau. In this paper the beach nourishment project is modeled using GENESIS model, and a result which fits well with the measured shoreline is gotten. With the same model and parameters, long-term performance of the project is simulated, and the result shows that without follow-up nourishment and project, the bathing places can keep suitable for bathing in only 2 to 3 years. So it is proposed to nourish the beaches in time to keep the beach’s use in recent years and carry out the beach nourishment project of west beach as soon as possible.
