Abstract

The coastal energy level off the Apalachicola River delta (panhandle coast of Florida) appears to be adequate to handle approximately 2 X 10 4 m 3 of sand and coarse silt per year. The river, through much of its recent history, has probably been delivering approximately 5 X 10 5 m 3 of bed load per year. Over a 5,000 year period this projects to an excess of approximately 20.5 X 10 9 m 3 .The beach ridges, barrier islands, and furrowed offshore shoals in the area may have been formed as severe storm waves redistributed this load. The amount of sand stored in these geomorphic features is estimated to be approximately equal to the projected 5,000-year excess. An energy-vs-load chart is presented as an aid in the evaluation of coastal features.
