Abstract
In one embodiment, a field-deployable acoustic camera system is provided for measuring a two-dimensional velocity field in a large scale flow in a turbid environment. The system includes an acoustic camera and a concentrator lens. The concentrator lens operates to reduce a spreading angle of the acoustic camera. The system is configured to apply planar cross-correlation velocimetry to collected images of native micro-bubble and/or suspended particle motion collected in turbid environments such as lake circulation, riverine, estuarine, and coastal flows, as well as turbid flows that occur near dredging operations.
