Sediment Sampling & Remote Boat Trial Operation May 1-2

Current Opened Gates: depending on the sediment sampling

Remote boat’s electric devices (Sonarlite and GPS system) were delivered to Oceanscience to check connection between Sonarlite and GPS system.

No GPS positions are exported from Sonarlite (echo sounder and data logger). Figure 1 shows measured data exporting using “Sonar XP” computer program and ASCII format data.

Numbers in red box (5^th column) are water depth, and data and time are following in the row. 2^nd, 3^rd, and 4^th columns should be GPS positions for latitude, longitude, and altitude, but

just zero values are exported. The GPS system (Trimble DSM 232) is working correctly by itself. The coordination observed in LCD panel of the GPS is correctly located at the intake

structure as shown in Figure 2 (Google Earth).

Suspended sediment sampling test was in progress with COA/WUA and URS engineers (Figure 3).
