Abstract

A one-year set of subaerial beach profiles from the southern Mediterranean beaches of Israel, measured at fortnightly intervals, was analysed by applying eigenfunctions and computations of scour-and-fill. The eigenfunction associated with the first eigenvalue is shown not to be efficient for beach categorization. However, the second eigenfunction effectively classified three subenvironments of the exposed beaches. These constitute the upper foreshore, the stable segment and the upper backshore. A model of subaerial beach types, based on the second eigenfunction, is confirmed by scour-and-fill indices and by morphological characteristics.
