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.

Example of a camera system that will be tested to measure water level and surface velocity at the East Branch Brandywine Creek below Downingtown, PA.

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.

The AVM-measured velocity used to index mean velocity can be the line velocity from one acoustic path or from multiple acoustic paths.

2" galvanzied pipe mated to a custom PVC clamp mount are used to fasten a horizontal ADVM.

A 4" aluminum I-beam is used allow an ADVM to be raised and lowered on a stainless steel sled.

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

Diagram depicting stationing in midsection measurement where velocity measurements are acquired. Each station width is multiplied by the station depth and measured velocity to compute the discharge in each section. Section discharges are tabulated to compute a total discharge for the cross section.
