Abstract

Abstract

Beach stratification usually consists of two parts, i.e. the seaward-dipping beddings on the foreshore side and the landward-dipping beddings on the backshore side. Through the study of 10 trenches perpendicular to the shoreline in Yantai and Laizhou, it is found that most of the beach stratification in the trenches is dipping landward with an inclined erosion surface on the top. And the seaward-dipping bedding is only a few dozen centimeters thick due to the erosion of storms in the past decades. In some trenches, the sequence is dominated by seaward-dipping beddings, indicating a silting environment. In conclusion, the characteristics of beach stratification could be used as a dynamic indicator of beach evolution.
