Data Collection:

Equipment:

    1. Aire Cataraft pontoon boat.
    2. Trimble 4400 Total Station survey grade GPS rover unit (output one position fix per second with 2-3 cm accuracy).
    3. Radio to receive real time correction information for GPS Base station on shore.
    4. Scientific grade sonar at 200 kHz (depth accuracy 7 cm).
    5. Acoustic Doppler Profiler to measure current velocity.
    6. Three laptop computers to provide ArcView Tracking Analyst display and collect data from sonar and ADP.
    7. DC/AC inverter to power electronics
    8. Organic interface - Bill (only one of the two required units is shown).

Concurrent with the bathymetry, information about flow velocities and the edge of water are collected for use as boundary conditions in the hydraulic models.
