USGS employee John Fulton prepares an unmanned aerial vehicle for take off. This particular drone referred to as "Q-Cam" measures surface water stream velocity. Combined with a second drone, non-contact discharge measurements can be made.

Profilers measure velocities in uniformly-sized cells or bins along the acoustic beams (fig 1). By measuring velocities in a number of bins across a channel or vertically through the water column, these instruments produce horizontal or vertical water velocity profiles, hence the designation "profiler.

The AVM measures the average water velocity along the acoustic path (VP, figure 1); then computes the "line velocity," the velocity component parallel with the average downstream flow line.

6" PVC pipe is weighted to allow an ADVM/ADCP to be deployed in a vertical or "uplooker" configuration.

Old custom made Kentucky-style mount on several different boats from Kentucky and Illinois deploying both Broadband (BB) and Rio Grande ADCPs. A pole can be fixed to the mount for deploying a GPS antenna located on top of the ADCP. The Kentucky-style mount constructed of Speed Rail is recommended for Rio Grande Workhorse, RiverPro, RioPro, and Sontek M9.
