Abstract:Investigations of geomorphology and sediments of beaches were carried out in 10 representative beaches such as the Shuangdao Bay beach, the International bathing beach, the Golden bathing beach, the beach west of the Qingjidao Island, the beach east of the Qingjidao Island, the swan lake beach, the Sanggou Bay beach, the Zhudao beach, the Nanhai New District beach and the Rushan silver beach. Combining with the analysis of surface samples collected from the beaches, the beach geomorphology and the grain size distribution and quality of the beach sediments in the study areas are evaluated comprehensively. The sediments of the beaches in Weihai City are mainly composed of gravel sand, coarse sand, medium sand and fine sand. Of them, the medium sand is distributed most widely and accounts for 35.6% of all survey stations; the next is fine sand, which accounts for about 34.4% of all stations; the coarse sand accounts for about 26.7% and the gravel accounts only for 3.3%. The slope of the beaches is gentle in general and the width of the beaches is above medium. The beach quality is better on the whole, but some of the beaches are slightly worse in their quality due to the effects of sediment grain size.
