I-A "Laboratory Investigations of the Vertical Rise of Solitary 

 Waves on Impermeable Slopes" by Jay V . Hal 1 , Jr . , and 

 George M. Watts 



Empirical relationships between wave height, water depth, 

 slope angle, and maximum elevation reached by a solitary 

 wave running up the slope are derived by laboratory 

 experiment. Measured wave velocity is also compared 

 with theoretical values.

II-C "Development and Field Tests of a Sampler for Suspended 

 D Sediment in Wave Action" by George M. Watts 

 F 



The development of a mechanical sampler to extract a 

 representative sample of suspended sediment and measure 

 the quantity of water from which it is extracted where 

 material is in suspension due to wave action is described. 

 Results of field tests with analysis of their significance 

 made at Pacific Beach, California are also presented.

II-A "Analysis of Moving Fetches for Wave Forecasting" by 

 Kenneth Kaplan 



An jinalysis is presented in the interest of standardizing 

 and simplifying wave forecasting procedures, £Uid of making 

 possible accurate wave forecasts by those with only a 

 cursory knowledge of meteorological and wind wave theories. 

 Changing weather situations which are possible between 

 weather charts are grouped in eight categories according 

 to relative positions of fetch front and rear and the 

 energy front on successive weather charts, and relative 

 lengths of the first chart's measured and minimum fetches. 

 The eight situations are analyzed and forecasting pro- 

 cedures developed for each.

C Thorndike Saville, Jr.

 hindcasts from synoptic weather charts for the 3-year
