procedures. The average monthly wind roses and the average annual wind rose, 

 based on LEO data collected between 27 July 1977 and 28 December 1979, are 

 presented in Figure 12. These data were taken from values obtained using a 

 Dwyer wind meter at the seaward end of the FRF pier. Figures 13, 14, and 15 

 are graphs of the longshore current magnitude, direction, and monthly mean 

 versus time for the pier-end LEO site. 



A wave rose for the overall reporting period (1977-79) , based on the sin- 

 gle visually observed estimates of wave height and direction of wave approach 

 at the seaward end of the FRF pier, is presented in Figure 16. Figures 17 and 

 18 show the annual wave roses for 1978 and 1979, respectively; Figures 19 and 



20 are summer (April to September) and winter (October to March) wave roses 

 for 1979. Although the estimated wave height appears to agree reasonably 

 well with the instrument data obtained at the same time, it should be noted 

 that these conditions do not reflect daily averages; the LEO data are daily 

 instantaneous values indicative of the conditions at about 0700 e.s.t. 



6. Sediment Data . 



At least monthly and often weekly sand samples were taken from the fore- 

 shore at a beach site approximately 150 meters north of the FRF pier. Figure 



21 shows the mean sediment diameter versus week of the year. The data for 

 April 1978 through the end of 1979 represent the visually estimated size of 

 the predominant sand grain size in the sample and seem to show an observer 

 bias when compared with the settling tube data from the CERC Rapid Sediment 

 Analyzer (RSA) . The results of a more detailed sediment survey performed in 

 August 1979 are presented in Appendix C. 



7 . Survey Data . 



A bathymetric survey was performed in October 1979. Figure 22 is a con- 

 tour diagram of the resultant bathymetry, and Table 1 (see Sec. IV) lists the 

 ranges surveyed, their distances from the pier, and the extent of the ranges 

 offshore. Figure 23 shows the locations of the survey ranges in the vicinity 

 of the FRF. Figures 24 and 25 show the comparisons of the northern and south- 

 em ranges, respectively, for the overlapping parts of the beach profiles from 

 surveys during 1978 and 1979. 



Weekly pier surveys from both sides of the pier were performed; Appendix D 

 contains monthly overlay profile plots for the data. Annual and overall enve- 

 lopes of the profiles for all the surveys are shown in Figures 26 and 27. 

 Figure 28 shows the time history of the bottom elevations for the pier-end 

 Baylor, nearshore Baylor, pier-end and nearshore tide gage locations, and a 

 number of the other survey stations along the pier. 



8. Photographic Eata . 



Quarterly aerial photography oiissions were flown as part of the measure- 

 ment program. The data are stored in film canisters as continuous rolls of 9- 

 by 9-inch photographic negatives (see Fig. 29 for photo sample). Table 2, 

 which is in Section IV, itemizes the photographic missions. Daily ground 

 photos of the beach looking north and south from the FRF pier were obtained, 

 starting in August 1979. Figures 30 and 31 present samples for the north and 

 south beaches, respectively.
