different values of fetch length and storm speed 

 were investigated numerically, and the primary 

 results summarized in graphical and tabular form.

I I -A "Wave Forecasting Relationships for the Gulf of Mexico" 

 by Charles L. Bretschneider 



The methods utilized in obtaining hindcast statistical 

 wave data for locations in the Gulf of Mexico (pre- 

 sented in Technical Memoremda Nos. 85-89) are discussed. 

 A numerical method of forecasting wave generation and 

 propagation over a sloping bottom taking into account 

 both generation by wind and dissipation by bottom 

 friction is demonstrated. Also shown are the averaging 

 techniques used to apply the method to statistical 

 accumulation of hindcast data in the Gulf of Mexico.

TI-A "Wave Statistics for the Gulf of Mexico off Brownsville, 

 Texas" by Charles L. Bretschneider and Roy D. Gaul 



Detailed statistical wave data for deep water, 96, 48, 

 24, and 12-foot depths, based on hindcasts from synoptic 

 weather charts for the 3 years 1950, 1952, 1954, are 

 presented. Refraction coefficients and final wave 

 direction at those depths are also presented graphically 

 as a function of wave period and deep water wave direction.

II -A "Wave Statistics for the Gulf of Mexico off Caplen, Texas" 



by Charles L. Bretschneider and Roy D. Gaul 



Detailed statistical wave data for deep water, 96, 48, 

 24, and 12-foot depths, based on hindcasts from synoptic 

 weather charts for the 3 years 1950, 1952, 1954 are 

 presented. Refraction coefficients and final wave 

 direction at those depths are also presented graphically 

 as a function of wave period and deep water wave direction.
