APPENDIX A: DATA 



1. This appendix contains a listing of the basic data collected during 

 the DUCK85 surf zone sand transport experiments. Data are given for the 

 following quantities: 



a. Wet weight of collected sand (Table Al) . 



b. Trap locations in the Field Research Facility (FRF) coordinate 

 system (Table A2). 



c. Current meter locations in the FRF coordinate system (Table A3). 



d. Water levels during the experiments (Table A4) . 



e. Beach profiles in the vicinity of the experiment (Table A5). 



f . Calculated transport rate densities for eight cross-shore runs 

 (Table A6). 



g. Grain size data (Table A7). 



2. Table Al gives the weight of the sand collected in the streamers as 

 recorded in the field logbooks, without adjustments for trap efficiency. A 



value of '0.0' indicates that no sand was collected in the streamer and ' ' 



denotes no streamer at that elevation. The wet sand was weighed in a drip- 

 free state in small patches of sieve cloth, and the weight of the sieve cloth 

 was subtracted to arrive at the values given in Table Al. The drip-free wet 

 weight (WW) and the dry weight (DW) of samples consisting primarily of sand 

 are linearly related (Kraus and Nakashima 1986)* for a wide range of common 

 grain sizes and sample weights as: 



DW = c WW (Al) 



for which the empirical coefficient c must be determined through calibration 

 for the particular field operation and weighing procedure, since judgement of 

 the drip-free state is somewhat subjective. The value c = 0.76 was obtained
