Abstract

X-band radar measurements have been applied for rip current observation. Radar images were collected at research pier HORS on a straight sandy coast. Rader images capture wave propagation, breaking and run-up motions. Hourly averaged images have been processed, which frequently display characteristic cross-shore patterns that resemble to neck and head of a rip current. Floater experiments and radar measurements were done simultaneously to confirm rip current pattern and flow speed. Wave propagation speeds on rip channel were smaller compared to that of outside with same magnitude of the offshore-wards drift speed of floaters. Temporal variation of wave celerities at inside and outside of a rip current was measured for several tide cycles. The difference was large for low tides suggesting growth of rip current.
