Nature and Genesis of Some Storm Washover Deposits.
Abstract
Freshly formed small-scale washover deposits were examined along a section of the Atlantic coast (Outer Banks, North Carolina) and Lake Erie (Presque Isle Peninsula, Pennsylvania) to determine their stratigraphic properties, mode of placement and relationship to adjacent barrier (spit) morphology. Storm washover occurrence is a function of the degree of storm surge and backshore-foredune relief. The shape and dimension of the resulting washover sand body is largely controlled by surrounding topography. Overall textural distribution, modality, and skewness of samples from the adjacent washover, foredune and beach show a strong similarity. Washover contributes to landward and vertical accretion of relatively coarse detritus in the barrier environment, thus serving as temporary sediment sink in an erosional (transgressive) littoral drift system.
