c. Littoral Current Observations 



The littoral transport observations include measurement of 

 littoral current speed, and determination of the direction the current 

 is going. 



d. Beach Observations 



The beach observations include measurements of the berm- crest 

 elevation above a reference datum, the berm-crest distance from the known 

 reference point, and the slope of the foreshore. 



e. Tide Level 



If known, the relative state of the tide is recorded. 



f . Water Temperature 



Water temperatures are recorded at the discretion of the 



observer. 



g. Rip Currents 



The presence of rip currents and the spacing of these currents 

 are recorded. 



h. Beach Cusps 



The presence and spacing of beach cusps are recorded. 



i. Photographs, Sand Samples and Comments 



In addition to the above, photographs are made of the shore- 

 line at each particular site, and sand samples taken from the foreshore 

 slope of the beach. Remarks or comments by the observer regarding unusual 

 conditions of the beach are also recorded. 



Surf and wind are observed twice a day; littoral currents, beach 

 dimensions, rip currents, beach cusps and water temperature are observed 

 once a day; photographs and sand samples are taken once a month. 



5. Recording Form 



At the initiation of planning and coordination of this program, 

 it was evident that the volume of data would soon become unmanageable 

 unless it could be recorded. in a standard manner capable of speedy and 

 convenient handling. This led to the design of a specialized form em- 

 ploying optical scanning techniques which facilitate automatic processing 

 of data by a computer.
