Abstract
Techniques for measuring one or more physical properties of a water system. A measurement platform is positioned at a first location of a given water system, wherein the measurement platform comprises a plurality of sensor devices distributed over a three dimensional space and configured to acquire data relating to one or more physical properties of the water system. A first set of measurement data is acquired from the water system at the first location via at least a portion of the plurality of sensor devices of the measurement platform. The measurement platform is moved along a predetermined path to at least a second location in the water system. At least a second set of measurement data is acquired from the water system at the second location via at least a portion of the plurality of sensor devices of the measurement platform.
