Abstract
Longshore current is main transportation mean causing movement of bed load and suspended particle in coastal waters, and effective measurement method and suitable equipment for shallow water coastal environment where is frequently exposed to atmosphere. Measurement equipment for longshore drift was designed and miniature model was applied to Gyeongpo beach in May and June, 2014. The equipment consists of three main elements, spheroid outer casing, spheroid inner casing, observation module equipped with GPS. Gyroscope principle was applied to observation module, and GPS receiver always can be directed upwards. Miniature models were installed along Gyeonpo beach, and it was well to track the flow of longshore current. This research described the design and function of the equipment and results of field experiments.
