Remote Boat Water Depth Calibration - June 20 ~ 22

Current Opened Gates: Automatic for 3.0 ft water depth

Water depth was set 3.0 ft with automatic gate operation and 2.89 ft water depth was shown in the PLC screen at 8:50 am.

Water depth survey with the remote boat was conducted based on the phone conference discussion opened on 18-June.

Three different system setting were tested: no GPS receiving; GPS receiving 1 per 2 seconds; and GPS receiving 1 per 5 seconds.

All of the settings are still showing intermittent GPS data lodging. However, after the surveyed data filtering, the data were transferred

to reasonable values as shown in Figures 1 and 2.

Dark blue lines show the channel bed level front of the intake structure. Contour of the sediment submerged vanes were detected as shown

Figure 1 in green colored circles. Gage height hydrograph along the Rio Grande is posted.
