In 194.7 and 194.8 , approximately 14 million cubic yards of sand was 

 deposited on central beaches of Santa Monica feyo (See figure) The 

 beach was widened some 600 feet from Hyperion northward a distance of 

 seven miles to the Ocean Park Pier^ This wide section of beach is to 

 be developed with access roads, parking areas j and playgrounds, and it 

 will be of immeasurable value to the people of Los Angeles County, as 

 well as to the beach cities of Ocean Park, Venice, Playa del Rey, and 

 Manhattan Beach » 



The field research group is conducting a sand movement study in 

 this areao As mentioned before, a wave recording station was establish- 

 ed on the end of the EL Segundo pier, near tte center of the Santa 

 Monica Bay shore line, and seasonal volumetric surveys are being madeo 

 Daily littoral current readings are taken in cooperation with Los 

 Angeles County authorities, and beach and offshore sand samples are 

 taken o 



Littoral drift is quite variable in this large bay, and the study 

 of sand movement is further complicated ly a deep submarine canyon off 

 Redondo Bsach that approaches within a few hundred feet of the shore o 



The fill was not completed until October 19^8 and its slopes 

 have not yet reached equilibriumo Preliminary studies indicate a net 

 downcoast movement of sand over the fill area at a rate of about 1,300 

 cubic yards per dayo This rate will lessen considerably as the fill 

 stabilizes This study will natiirally be of value in determining the 

 rate at which this filled beach will need replenishment, bit it will 

 also provide us with basic knowledge which will be very helpful in 

 studying similar situations elsewhere » 



The second project is in the vicinity of Anaheim ]fey, California » 

 From October 194.7 to January 194.8, approximately 1,100,000 cubic 

 yards of sand was deposited on the beach fronting the Surfside Beach 

 Colony and the Anaheim fey Naval Ammunition Depoto The beach had been 

 denuded due largely to interruption of the dosfncoast littoral movement 

 of sand by the jetties protecting the Anaheim fey entrance o 



The field research group has been studying the movement of this 

 fill since March 1948 » A wave station has been established at the 

 seaward end of the Huntington feach Pier, and volumetric surveys and 

 littoral drift studies are being made from Anaheim fey south to the 

 mouth of the Santa Ana River, a distance of eleven miles o 



The littoral drift in this area is predominantly upcoast in the 

 summer, due to waves from storms generated in the Southern Hemisphere, 

 and downcoast during the rest of the yearo As a result, the rate of 

 littoral sand movement has varied during the seasons from about 200 

 cubic yards a day upcoast to about 2,500 cubic yards a day dovmcoasto 

 The net movement in the vicinity of the fill from April 1948 to 

 February 1949 was about 600 cubic yards a day to the south
