This article describes the succession of estuarine types. Processes 

 which produce this succession are discussed, including barrier island 

 migration by overwash.

Schwartz, M. L. 1971. The multiple causality of barrier islands. Journal 

 of Geology 79(1) :91-94. 



Urges that multiple causality of barrier islands be more widely accepted 

 and presents a suggested classification on this basis.

*Swift, D. J. P. 1975. Barrier island genesis: evidence from the central 

 Atlantic shelf, eastern U.S. Sedimentary Geology 14(1 ) : 1-43. 



Discusses barrier island formation in relation to the Middle Atlantic 

 Bight. Concludes that since most major barrier systems form on flat 

 coastal plains, it would appear that mainland-beach detachment is the 

 more important mode of barrier formation.

transport: process and pattern. Dowden, Hutchinson, and Ross, Strouds-

This volume contains papers presented in a symposium on shelf sediment 

 transport conducted at the annual meeting of the Geological' Society of 

 America in Washington, D.C., November 1971. The volume, organized in 

 three sections, is concerned with shelf hydraulic regime and mechanics of 

 sediment transport, suspended sediment dispersal, and bottom sediment 

 dispersal .

 in barrier island topography. Journal of Geology 84(5) :583-594. 



Eigenvectors of a matrix of 530 profiles were calculated to quantify 

 systematic topographic variations in Atlantic and Gulf coast barrier 

 islands.
