May, and the model automatically shut down half the breach side erosion at that
time. Rapid initial growth of the breach is well reproduced, and calculated
breach width and depth approach equilibrium. Prior to the March 1980 severe
storm, the simulated breach appeared to begin approaching an equilibrium state.
Subsequent storms (Fig. 6) continued deepening and opening the breach.
