A new inlet was opened 4.5 miles north of Cape Hatteras, North Carolina, during a great storm March 5-9, 1962. Aerial photographs permit the determination of the rate of growth of a new tidal delta built by sediment carried into the lagoon through the new inlet 5 days, 2 months, and 10 months after the opening of the inlet. Areal extent of the delta at these intervals was respectively 0.11, 0.2, and 0.35 square miles. Time-lapse photography provides an excellent basis for measuring rates of growth of depositional land forms.
