Quantification of Shoreline Meandering.

Abstract

Rhythmic, shoreline topography, termed shoreline meandering was investigated along Hatteras Island, North Carolina, using historical aerial photography. Two types of meanders were distinguished on the basis of form geometry. The temporal and spatial variability of meandering along the island were quantified using spectral and multivariate techniques. The data suggested that a model of the beach cycle in the nearshore zone in which the occurrence of small meanders is a function of (1) storm-current velocity and nearshore slope and (2) a post-storm balance of onshore and offshore sand transport due to the presence of topography-forced nearshore circulation explains the observed characteristics of small, rhythmic meanders. Large meanders are explained as regions of severe storm erosion caused by wave convergence over long, offshore shoals. (Author)
