Figure 5. “The effect of the auto-rereat concept shown by a deltaic shoreline trajectory, as proposed by Muto and Steel (1992). If relative sea level is rising at a constant rate and if other external forces are constant, the shoreline undergoes a retreat after a relatively brief period of progradation. The retreat is due to the progressive increase in the effective surface area of the delta. A constant supply of sediment falls far short of allowing a steady accretion of clinoforms.” (Figure and caption from Muto and Steel, 1997, with kind permission of SEPM.)
