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. Web11 jun. 2024 · Macro-tidal rip currents are typically associated with extensive, well-developed 3D morphology located around the spring low-tide limit, where there is sufficient tidal stationarity to allow large length-scale bar/trough systems to develop ( Masselink and Short, 1993; Scott et al., 2011 ). shooks auto graham tx
