current and one with a southerly directed current. Complete photopole and 

 current data sets are available for two runs (only photopole data are avail- 

 able for Run 8609111745). 

 Consistency tests 



36. Consistency tests were performed to compare collected quantities of 

 sand from traps placed in close proximity to each other. These tests were 

 used as an indicator of trap reproducibility and reliability in the field. In 

 the consistency tests, two traps were placed in the surf zone approximately 



1 m apart. The seaward trap was located a distance sufficiently downdrift of 

 the shoreward trap (typically, about 1 m) so that sand scoured from the 

 seaward trap and transported shoreward with the incoming waves would not be 

 collected by the shoreward trap. Consistency testing was conducted as a part 

 of several TSM runs by deploying trap pairs . Waves and currents were measured 

 during consistency tests, and all current meter data have been analyzed; 

 however, wave data sets are only available for TSM Run 8609201500 (includes 

 two consistency tests) and Consistency Run 8609160945 (partial wave data set) 

 (see Ebersole and Hughes, in preparation). 

 Rip current measurement 



37. An experiment was performed on 12 September with the objective of 

 measuring sand transport in the rip current located near the north FRF 

 property line. Two traps were placed in the south longshore feeder current of 

 the rip, one trap in the north feeder current, and three traps in the throat 

 of the rip. Streamers on traps placed in the strong offshore current flow in 

 the rip throat extended seaward, directly against the incident waves. Neither 

 current nor wave data are available for the rip current run. 



Currents 



38. The two current meters bracketed the deployed traps, and were 

 placed slightly down- current . The meters were moved as necessary as trap 

 deployment location changed with the tide. The basic processed current speed 

 data (mean and standard deviation) are given in Table 4 for 17 runs. Columns 

 in Table 4 represent x- and y- components of the current in the experiment 

 coordinate system, for the meters 1 and 2. The x-axis points offshore
