Changes in ebb-tidal delta morphology at Price Inlet, SC (May 1973 to August 1977)
concept states, the constriction causes an increase in current velocity which leads to greater
scouring of the inlet channel and re-establishment of the equilibrium channel cross-sectional
area. Because longshore transport along most coasts adds sand predominantly to one side of the
inlet, the opposite side erodes preferentially causing the inlet to migrate (Johnson 1919). The
rate of migration is dependent on sediment supply, wave energy, tidal current strength, and
composition of the channel banks. If a migrating inlet becomes entrenched into resistant
sediments, further migration will be impeded. Shallow inlets tend to migrate and deeper inlets
tend to be more stable because there is a greater likelihood that their channels have scoured into
