Fair-Weather versus Storm Beach: An Example from The Goa Coast

The Goa coast of southern India is affected by short-term storm events during summer which perturb the fair-weather beach equilibrium considerably. The storm surge ebb at Goa coast moves perpendicular to the shoreline and deposits its load in the form of shore-parallel ridges. Renewal of fair-weather condition throws the storm profile into disequilibrium and exposes part of the storm-induced ridge field. The effort for re-equilibration establishes a new beach profile in which the part of the storm-induced ridge field turns into backshore.
