V. Observations/Measurements and Frequency 



A. Basic Observations - As envisioned, the study will consist of the 

 collection and recording of observations or measurements on various forces 

 concerned with littoral processes and the response of the shoreline to 

 these forces. The basic observations/measurements and frequency desired 

 are: 



1) Wave Observations: twice daily; height, period, direction 

 and type of breaking wave. 



2) Wind Observations/Measurements: twice daily; velocity and 

 direction. 



3) Littoral current observations/measurements: daily; velocity, 

 and direction. 



4) Beach measurements: daily; berm width and elevation, and 

 slope of foreshore beach. 



5) Photographs: Monthly; general panoramic photographs of the 

 beach in up and downcoast direction. 



6) Sand samples: monthly; small samples from the beach foreshore, 



B. Optional Observations - In addition to the observations /measure- 

 ments listed above, there are a number of additional items which may be 

 taken at selected study sites to the extent of available personnel. These 

 include but not limited to: 



1) Water temperature: daily. 



2) Tide level: twice daily; relative state. 



3) Rip currents - as observed. 



4) Beach cusps - as observed. 



C. Extent of Participation - Participation by the appropriate local 

 or state agency shall be subject to the extent of available personnel and 

 shall not take precedence over other duties of higher priority.
