Support facilities. Video documentation of all test runs was provided by 

 locating a camera on the roof of the elevated control room and panning the 

 beach area. The camera shutter plane was located at x = 167.5 ft (51.1 m), 

 y = 32.5 ft (9.9 m), and z = 28.9 ft (8.8 m) in the SUPERTANK coordinate 

 system. The coordinate system origin was located at the top of the right 

 inside wall of the wave channel, above the vertical rise in the channel bottom 

 from 15 ft (4.57 m) to 3 ft (0.91 m). A Panasonic WV-D 5100 color video 

 camera was used to acquire analog videos in the V£-in. VHS format. A photo- 

 graph of the camera appears in Figure 13-12. Offshore underwater videos of 

 bed forms were acquired for several intermediate runs. A camera and light 

 were cantilevered from the wall inserts at Station 19. The submersible camera 

 is a Deep Sea Power and Light model SC-2000 with a wide-angle lens. A 

 photograph of the camera, light, and 3.0-in. (7.6-cm) grid appears in Fig- 

 ure 13-13. 



An elevated platform was provided for video measurements of wave runup 

 on the beach. This video platform is shown in Figure 13-14.
