APPENDIX B: HYDRAULIC TEST DATA 



1. This appendix presents tabulated data measured in the hydraulic 

 efficiency tests. Flow speeds were measured at 3 to 9 points in each nozzle 

 (measurement locations referenced in the tabulation are numbered in 



Figure 16). Tests were conducted with the nozzle at a near-bed elevation 

 (BOT), at a midflow elevation (MID), or with two nozzles (2ST), one at each 

 the near-bed and midflow elevation. For the two-streamer tests (2ST), data 

 were collected first from the upper (midflow) nozzle, followed by measurements 

 at the near-bed nozzle. Measurements were made both with the trap in place 

 (TR) or without the trap (ambient, AM). Tests that were repeated are distin- 

 guished by a "-1" and "-2" (e.g., BOT-1, BOT-2) in the table. 



2. Values of hydraulic efficiency Ej, represent the ratio of trap (TR) 

 to ambient (AM) flow speed (see Equation 7, Part III). The nozzle character- 

 istics examined are defined and discussed in detail in Part III of the main 

 text.
