Low tide bar/rip
Web6 mrt. 2024 · Everyone enjoys visiting the beach and playing or swimming in the water, but sometimes, waves breaking on beaches can create strong, narrow currents that can pull you out of your depth and into deeper water, where you may find yourself in trouble. We call these rip currents, and they are the main cause of drowning and rescues on surf … Web1 apr. 2013 · low tide bar/rip morphology on a seasonal time scale (Austin et . al., 2010).

Webmacrotidal rip systems from the perspective of the flow dynamics and surf zone circulation. A field experiment was conducted on a macro-tidal beach (range 6.3 m) with low-tide bar/rip morphology to quantify the circulation and dynamics of the rip current systems. Measurements of flow velocity, water depth and suspended sediment WebIt can be classified as a low tide bar – rip beach and exhibits a relatively flat inter-tidal zone with pronounced rhythmic low tide bar - rip morphology. Data were collected over two field campaigns, totalling 14 tidal cycles and including 27 occurrences of rip currents, in a range of offshore wave heights (Hs = 0.5 – 3 m).
WebThe strongest rip velocities have been observed at low tide (Aagaard et al (1997), Brander and Short (2000), MacMahan et al (2005)) while during high tide, more waves propagate over the bar without breaking and the rip current is weaker or completely inactive. WebAt low tide, dissipation over the bar crests was reduced by partial bar-emergence and observations suggested that rip flows were maintained by morphological constriction and the side-drainage of water from the transverse bars. & …
