On a geomorphological basis, coastal fordune development is part of the dune/beach profile and it's the product of sediment budget interacting with dune and beach processes. Dune dimension and form are part of sequential evolution of the sand storage morphology ant the upper portion of the dune/beach profile. An understanding of the basic patial/temporal model of foredune development can lead to an understanding of the complexities and permutations that comprise specific regional foredune assemblages. Fordune Development is and active, dynamic process that can evolve in several directions along a spatial and /or temporal contimuum. A demonstration of the basic model, its interaction with the beach and foredune sediment budget, and its application to several along a spatial and /or temporal continuum A demonstration of the basic model, its interaction with the beach and froedune sediment budget, and its application to several field sites establishes the characteristics of the fordune at several points on the soninuum and the development of a regional coastal foredune assemblage. The regional pattern illustrates the fundamental control of sediment supply in the system
