Systematic Variations in Inshore Bathymetry

Abstract

In order to investigate systematic geographic variations in subaqueous beach-zone morphology, the authors analyzed profiles taken from the shoreline to 1200 feet (365 m) offshore along the United States Atlantic and Gulf coasts for characteristic forms using an eigenvector analysis. The first three eigenfunctions derived accounted for more than 97% of the topographic variance in the profile data. The first eigenfunction represents slope departure from the mean; the second and third functions are related to variations in bar/ trough morphology. Because of the orthogonality of the various eigenfunctions, the report concludes that there is no relationship between profile slope and presence or absence or number of bars on the profile.
