direction as the wheel rolls along the surface of the sand bed. The servo motor
inside the profile indicator maintains a continuous downward force on the bed
equivalent to a mass of 40 g. After the sensor reaches the shoreward end of the
transect, the system raises the sensor to the fully retracted position, which
completes one transect. This process is repeated for each transect selected in the
PV-12 Profiler Operation panel. During the survey process, the x, y, and z
positions of the sensor are displayed real-time in the lower left corner of the PV-
12 Profiler Operation panel.
Because the moveable-bed beach is 30 m long, it requires approximately 60
transects to complete a bathymetric survey, with one transect every 0.5 m along
the beach. Therefore, three PV-12 Profiler Operation panels are normally used
