recording wave direction gage, are being installed on the seaward face of 

 the Huntington Beach pier, located at about the midpoint of the area under 

 study. 



Similar studies are underway in the Santa Monica area, except that 

 hydrograp hie surveys are run to a depth of sixty feet, mean lower low 

 water, with eight control profiles spaced throughout the area extending to 

 a depth of one hundred feet„ Considerable hydrographic detail is being 

 developed in the vicinity of the submarine canyon off Redondo Beach. 

 Sampling and hydrographic surveys will be extended south to Palos verdes 

 Point, the headland forming the southern boundary of Santa Monica Bay and 

 north to Topanga Canyon in an attempt to determine the extent of sand move- 

 ment- Recording wave amplitude, period, and direction gages are installed 

 on the seaward end of the El Segundo pier in the south and the Malibu pier 

 in the north sections of Santa Monica Bay to record wave characteristics 

 in this area= 



Wave hindcasts and wave refraction diagrams furnished by the Los 

 Angeles Engineer District, with wind and weather records for the period of 

 the study will be used. 



The various phases of the study will be expanded or modified depend- 

 ing on conditions met in the field as the project unfolds. The Anaheim 

 Bay area was selected for the first phase of the study since the sand fill 

 in the area had been completed and there was evidence of rapid movement of 

 the fill downcoast. Basic surveys and studies were started 1 April and 

 completed 12 April 194-8. On the following day the group moved into the 

 Santa Monica Bay area. Here the fill had not been completed so basic surveys 

 and studies were confined to the area extending from the new Hyperion sewer 

 outfall just above El Segundo, south to Palos Verdes Point. Basic surveys 

 and studies were completed in this area on May 10 and the group again moved 

 southward to the Anaheim Bay area for re-surveying and extending the 

 original surveys . 



Beach and bottom samples procured during the basic operations in both 

 areas are now being analyzed in the Board's offices. 



Wave gages are being installed on EL Segundo pier and on the Huntington 

 Beach pier and accompanying wave direction indicators will be installed in 

 the near future. 



The basic procedure as outlined above will be followed in the future. 

 First one area and then the other will be examined and the study expanded 

 or reduced as may be necessary to obtain complete information on the subject 

 project. Findings resulting from the analysis of the data taken during the 

 outlined portion of the study or those arising through experimentation on 

 any portion of the study or equipment will be published from time to time 

 in this Bulletin.
