PREFACE 



This report provides coastal engineers algorithms for a number of hand- 

 held calculator programs for coastal engineering, primarily in the area of 

 wave transformations and wave generation. These algorithms were developed 

 under the coastal engineering research program of the U.S. Army Coastal 

 Engineering Research Center (CERC) . 



The report was written by Dr. Todd L. Walton, Jr., Hydraulic Engineer; 

 William A. Birkemeier, Hydraulic Engineer; and Dr. J. Richard Weggel, Chief, 

 Evaluation Branch, Engineering Development Division.
