Sand Textual Distribution on Cross-Shore Slope at Gyungpo Beach in Korea

초록

The cross-shore slope represents an active portion of a shoreline, where wave run-up and run-down flow interactions occur with a littoral zone. The sand size is a significant variable when predicting beach morphology changes related to coastal erosion. However, there is a lack of information about sand size, sorting, skewness, and cross-shore slope on Gyungpo Beach, which is located in the eastern area of South Korea, for an understanding of its coastal environment. In this paper, the relationship between mean grain size and cross-shore slope has been investigated. In order to obtain accurate estimates of sand size parameters, sand samples were taken from the target beach using the traditional sieving method. The beach profile data, including the cross-shore slope, were collected using a VRS GNSS system mounted on a quad bike or on a surveyor's backpack. Several field data acquisition campaigns were conducted over a period of nine years. © 2024 IEEE.
