• Surf Zone - Shows how an ADV was used to collect data in the surf zone of a local San Diego beach.
• Dredge Head - Shows how an ADV can be used to map the field flow around a dredge head.
• Everglades - Shows how an ADV was used to measure low-flow fields by the USGS in the Everglades.
• Martha's Vineyard - Describes a laboratory evaluation and a field deployment of an ADV in the benthic boundary layer south of Martha's Vineyard during Hurricane Edouard by the Woods Hole Oceanographic Institution.
• Rio Grande - Describes a U.S. Bureau of Reclamation project using an ADV to obtain detailed velocity profiles in the Rio Grande low-flow channel near Socorro, New Mexico.
• Stennis - Shows how an ADV was used for low-flow studies around vegetation in a laboratory setting at the Stennis Space Center in Mississippi.
• Wave Field Measurements - Shows how several ADVs were used to study currents generated by a wave field at the U.S. Army Corps of Engineers Waterways Experiment Station in Vicksburg, Mississippi.
• Wave Flume Measurements - Shows how an ADV was used to measure the orbital velocities of a wave field within a flume.

• FlowTracker Handheld ADV

• Arkansas Stream Gauging Program - Describes the advantages of using a FlowTracker for stream-gauging measurements.
• Hot Spring Measurements - Describes how a FlowTracker was used to take measurements in a Yellowstone National Park hot spring.
• Indiana Stream Discharge - Describes how USGS personnel used a FlowTracker to measure discharge in eight Indiana streams.

• Tow Tank Test - Describes how the FlowTracker Handheld ADV was tested at a USGS tow tank.
• USGS Discharge Measurement Policy - The following link is to a Technical Memorandum issued by the U.S. Geological Survey's Office of Surface Water. This memorandum [pdf format] describes the USGS policy on the use of the FlowTracker for discharge measurements.
