We approached the problem from the viewpoint that if we could take the meteorological 

 data on the region, the duration and velocity of winds, and determine the wave energy from all 

 the winds which would develop waves at different parts of the coast and the variations from one 

 part of the coast to the next, we would have quantitative energy figures which would apply to 

 the shoreline study. 



The first consignment of the quantitative energy figures came in as I was writing this re- 

 port. I apologize for not having the report coordinated better, and not having the final correla- 

 tion table for the Navy's purposes, which I will be able to write now. The energy calculations 

 were made, as the reports show, by Dr. Warren C. Thompson and Charles L. Bretschneider. 



The figures will show you the characteristics of the continental shelf and the shoreline of 

 the Gulf of Mexico, and some of the methods by which this study is being made.

 couple of years ago. 



The deltaic coastal plains [ 1 ] * extend from the Apalachicola Delta in Florida around the 

 coast to the west and south to the steep young mountain- making coast of Tampico-Vera Cruz 

 [3] with a narrow continental shelf and coastal plain, where the influence of the Sierra Madre 

 Oriental is felt. ,
