In this study, erosion experiments using an annular flume of Chonbuk National University were carried out to quantify the erosion properties of cohesive sediments from Garorim Bay. The erosion properties were analyzed in connection with the physico-chemical properties of cohesive sediment, and analysis of local, seasonal and spatial variation was carried out. Erosion tests were conducted total 18 times for sediment samples collected twice in the fall and winter at two sites in Garorim Bay, and were performed under a uniform bed condition but a different bed density respectively.
Key Words: Garorim Bay; Cohesive Sediments; Physico-chemical Properties; Critical Shear Stress for Erosion; Erosion Rate
