The beach accretion process associated with a slip-face ridge and runnel (RR) system was studied using the numerical process-based morphodynamics model CSHORE (Johnson et al., 2009). The model could reproduce formation and growth of the RR system observed previously on a steep meso-tidal engineered beach (South Bethany Beach, DE) over the 2-week post-storm moderate wave periods. CSHORE including the ponded water effect in the landward runnel (Figlus et al., 2012) further predicted onshore migration of the RR system and establishment of a new berm-dune profile as the simulation continued with additional storm and following moderate wave forcing.
