1. A method of measuring a two-dimensional velocity field for a large scale flow in a turbid environment with a field-deployable acoustic camera system, the method comprising:
positioning the field-deployable acoustic camera system in the turbid environment, wherein the field-deployable acoustic camera system comprises an acoustic camera and a concentrator lens, the concentrator lens operating to reduce a spreading angle of the acoustic camera; and
measuring the two-dimensional flow velocity field in the turbid environment with the field-deployable acoustic camera system.
