Analysis of Rip Current Characteristics Using Dye Tracking Method

Rip currents are strong water channels flowing away from the shoreline. They can occur on any shore with breaking waves. play a significant role in changing topography of shallow regions by transporting large amounts bed material offshore. Moreover, they pose danger for people living nearshore zones and surfers cause hundreds deaths annually worldwide. Therefore, rip current generation characteristics have been investigated to prevent casualties. In this study, GPS drifter survey was chosen as investigation method; however, few drawbacks were discovered, such low accuracy due becoming trapped surf zone. drones dyes used overcome methods. The results dye tracking 3D wave-induced numerical simulation compared; velocity formation found be relatively similar. With technological advancements invention new equipment, techniques also evolve, paper shows that disadvantages GPS-based Lagrangian method using dye-mounted drone, which observes easily accurately.
