Abstract

This paper presents a detailed study of a beach nourishment project in Beidaihe, China. The study consists of a detailed assessment of a small-scale trial project that was carried out during May to June in 2008 to create two bathing sites on West Beach and a numerical evaluation of scheme options for the full project involving beach nourishment, groins, and submerged breakwaters. The monitoring data indicate that the nourished beach in the small-scale project was slowly eroding but in February of the following year the beach was still 20 m wider than it was before the project. The long-term shoreline evolution was then predicted using the generalized model for simulating shoreline change, which was calibrated to reproduce the posttrial project shoreline. The model indicates that without follow-up nourishment, the nourished beach created by the trial project will cease to be suitable for bathing in just 2–3 years. As to the full project the numerical evaluation of various scheme options indicates that the east groin plays a key role in protecting the beach in the long term and the removal of a rock jetty at east end of the beach in 2002 is identified as one of the major causes for the present severe erosion of West Beach. On the basis of the simulation results an optimum scheme for the project is proposed.
