    The strongest rips and associated feeder currents occur in association with intermediate transverse bar and rip topographies. Transitions between beach states are often caused by changes in wave energy , with storms causing reflective beach profiles to flatten (offshore movement of sediment under steeper waves), thus adopting a more dissipative ...
