Field Observation On Rip Current Formation At East Pangandaran Coast

Abstract

Rip current identification is carried out in various ways, such as using google earth imagery, drones, and cameras. In this study, identification is done by recording, and observing rip current directly from a high place using a camera for 9 hours, from 8 am to 5 pm, the purpose of this study is to determine the relationship between wave parameters and rip current parameters, wave parameters reviewed, namely, (Ho), (Tp), (Lo) (C) and tidal wave conditions, then the parameters of the rip current being reviewed are, the frequency of occurrence of rip currents, and the average length of rip currents. The results show that the frequency of rip current events is related to wave parameters, the greater the wave parameter, the greater the frequency of rip current occurrences, and the highest frequency of rip current occurrences occurring in sea conditions towards low tide with a wave height of 1.2 m, average duration The rip current in the Pangandaran East Coast Region is 11 seconds, the type of rip current that occurs is the flash rip.
