A manned boat is used to ferry the ADCP back and forth across the river. The velocities at this section were quite slow, and the line across the river allowed better control than driving the small boat.

Another view of the manned boat, with ADCP attached.

This is the cross section where the measurement was made and the line we strung across the river, marked with flagging for visibility. In slow velocities, the line helps control the speed of the boat as it is moved across the channel.

This is the view upstream of the cross section.

This is the view downstream of the cross section.

This ADCP sends an acoustic pulse into the water to measure the speed of the water, the depth of the river and to measure how far it's moved across the river. With this information, it can compute discharge.
