13. ABSTRACT 



This report describes the Littoral Environment Observation (LEO) Program, and 

 assembles in one paper the data collected under the program from February through 

 December 1968. LEO is a cooperative effort of the State of California and the 

 Corps of Engineers to collect information which will increase understanding of 

 the littoral processes and physical characteristics of the California shore. 



The littoral variables collected under the LEO program include the following 

 beach characteristics: foreshore slope, width and elevation of berm, presence of 

 cusps, and samples of the sediments. The beach samples are analyzed for mean and 

 median diameter, standard deviation, skewness, and kurtosis. Sea variables include 

 tide level, wave height, wave period, wave direction, type of breaker, direction 

 and velocity of littoral currents, presence of rip currents, and water temperature. 

 Wind velocity and direction are recorded, and panoramic photographs are obtained. 



The objective is to establish a bank of repetitive, systematic measurements 

 of meteorological and oceanographic forces affecting the shoreline and the 

 response of the shore to these forces. The data collected are being used as 

 a base to analyze physical characteristics of the shoreline and the littoral 

 processes affecting it.
