Abstract:

The tidal prism - inlet area relationships for inlets on sandy coast established by M.P. OBrien 1931 and 1969 were reanalyzed using his data and data published by other investigators. In addition, tidal prism and inlet cross-sectional area data developed in the Inlet Classification Study were also used. These data result in a total of 162 data points for 108 inlets--59 located on the Atlantic coast, 24 on the Gulf coast, and 25 on the Pacific coast of the United States. The data are grouped into three main categoriesL 1 all inlets, 2 unjettied and single-jettied inlets, and 3 inlets with two jetties. Regression analysis was performed on each set of data to determine the equations of best fit and to establish 95 confidence limits for the equations and the constants in the equations. The results of the regression analysis indicate that the tidal prism - inlet area relationship is not a unique function for all inlets but varies depending on inlet location and whether or not the inlet has been stabilized with a dual jetty system.
