BEIDAIHE BEACH NOURISHMENT: A CASE STUDY OF BEACH NOURISHMENT PROJECT IN BEIDAIHE
-
Abstract
Taking the beach nourishment project of Beidaihe as a case, the width of the dries and medium and low tidal flats and the unit deposition-erosion rate were calculated with the profile monitoring data of three years before and after the nourishment, and the evolution of beach profile shapes analyzed. Efficiency coefficient and preservation coefficient of beach nourishment were calculated. The efficiency coefficient of the dries, medium and low tidal flats of beach nourishment in Beidaihe were 5.37, 2.88 and 1.47, and the preservation coefficient were 1.01, 0.67, 0.75 respectively in the past 3 years. In this paper, we summarized the preliminary effects of beach nourishment in Beidaihe, and discussed controlling factors. The lifetime of the nourishment in Western Beach is about 10-12 years, the factors which influence the nourishment life include the length of nourishment beach, spatial bank protection system, volume of sand replacement and height of breaking wave.-
