APPENDIX C: NOZZLE PHOTOGRAPHS 



1. Streamer trap nozzle configurations investigated in the hydraulic 

 and sand- trapping tests described in the main text are illustrated in Figures 

 CI through C8. Nozzle height and width varied between 2.5 x 15 cm and 25 x 20 

 cm. Nozzle hoods, when present, ranged in length from 2.5 to 5.1 cm. Other 

 components such as streamer mesh size and a plexiglass door designed to shut 

 during flow reversals were also evaluated.
