PREFACE 



This report describes simple procedures for calculating the hydraulic 

 characteristics of a sea-inlet-bay system driven by the tide, as well as 

 for estimating the expected stable channel cross-sectional area for a 

 jettied entrance. It is based primarily on studies reported by King 

 C1974) and Jarrett (1976] and it was written under the tidal inlets 

 research program of the U.S. Army Coastal Engineering Research Center 

 (CERC) . 



This report was prepared by Dr. Robert M. Sorensen, Chief, Coastal 

 Structures Branch, under the general supervision of R.P. Savage, Chief, 

 Research Division.
