The West-central Florida coastline has 29 barrier islands, 30 tidal inlets, and the most diverse morphology of any barrier system in the world. New Pass and Big Sarasota Pass are situated along this microtidal, low-wave energy coast. The two closely spaced inlets carry a large tidal prism, on the order of 10 million cubic meters each. New Pass inlet has a mixed-energy straight morphology and Big Sarasota Pass has a mixed-energy offset morphology. The objectives of this study are to examine 1) the various factors controlling the morphodynamics of the two inlets, 2) interaction between the inlets and the adjacent beaches, and 3) morphodynamic response of the inlets and the adjacent beach to anthropogenic modifications. Time-series aerial photographs from 1943 to 2006 are digitized and compared. Tidal flow patterns through both inlets were measured using side-looking acoustic Doppler current profilers (H-ADCP).
