Observations have shown that the horns of crescentic bars may separate from the bar during storms and subsequently migrate onshore towards the beach during calmer periods as a spatially coherent structure, termed Shoreward Propagating Accretionary Wave, or SPAW. Here, we aim to (1) quantify the morphological evolution of a SPAW and (2) unravel the physical processes underlying its onshore migration and spatial coherence. To do so, we studied onshore migration of a SPAW using a process-based morphodynamic model.<br><br><b>Recorded Presentation from the vICCE (YouTube Link): <a href="https://youtu.be/5P22G_S0FJM">https://youtu.be/5P22G_S0FJM</a></b></html> ER -
