Abstract
Coastal managers and swimming beach managers are supposed to pay enough attention to safe utilization of recreational beaches. To ensure the safe utilization of a beach, it is better to detect a rip current location and special size, and use such information for public awareness program. Visualization such as an aerial photograph is probably informative for the purpose; therefore an inexpensive multi-copter system is applied to monitor a nearshore bathymetry, nearshore current especially a rip current in Uchinada beach, Kanazawa City, Ishikawa Prefecture, Japan in September, 2014. Dye and GPS float buoys are also applied to obtain qualitative and quantitative date of rip current. As a results, it is shown that a rip current visualization by a multi-copter system and dye are the most efficient and inexpensive technics for a rip current detection, except windy and rainy conditions. Video images by the system also can be applicable to study generation of nearshore current system.
