Abstract:
1. A method, comprising: positioning a measurement platform at a first location of a given water system, wherein the measurement platform comprises a first plurality of sensor devices distributed over a predetermined three dimensional space on the measurement platform and configured to acquire data relating to one or more physical properties of the water system, and wherein the measurement platform comprises a plurality of three-dimensional quadrilaterals stacked on each other including the first plurality of sensor devices at vertices of the three-dimensional quadrilaterals; acquiring a first set of measurement data from the water system at the first location via at least a portion of the first plurality of sensor devices of the measurement platform; moving the measurement platform along a predetermined path to at least a second location in the water system; acquiring at least a second set of measurement data from the water system at the second location via at least a portion of the first plurality of sensor devices of the measurement platform; and determining locations of the measurement platform at each of the first and second locations by localization using at least one of a second plurality of sensor devices positioned at an edge of the given water system and a global positioning system (GPS); tracking temporal variation of the given water system using a plurality of stationary sensor devices; determining, based on changes in values obtained by the plurality of stationary sensor devices, invalidity of a baseline model representative of one or more physical properties of the given water system; and updating the baseline model based on the temporal variation, wherein the updating comprises using the changes in the values and locations of the plurality of stationary sensor devices as boundary conditions to interpolate the changes across an entirety of the given water system.
