UC Berkeley’s Floating Sensor Network
Scientists and engineers at UC Bekerley are recently deployed a fleet of floating sensors into the Sacramento River in orderto measure the movement of water, salinity and pollution. More from the aptly-named float.berkeley.edu:
The Floating Sensor Network team will build 100 motorized drifters, which are communication-enabled andintegrate numerous sensors, including GPS, temperature, and salinity. The fleet will be deployable rapidly, inresponse to unanticipated events such as floods, levee breaches, and contaminant spills. The team is alsoworking on hydrodynamic models (one and two dimensional shallow-water equations) and inverse modelingalgorithms (Ensemble Kalman Filtering and its extensions) to integrate these measurements in the models.
Jointly with the Lawrence Berkeley National Laboratories and the California Department of Water Resources, theteam is developing a computational infrastructure which will run online (Web-based), and integrate in real-timethe measurements from static sensors (for example, USGS permanently deployed sensing stations), mobilemeasurements, and any other data feed available to us, to estimate river flow and contaminant propagation inreal-time, using online measurements. The results will be available to users in the form of “water maps”, thatshow the motion of water in real-time, and corresponding transported quantities (such as salt).
The idea of using floating, transceiver+GPS-enabled sensors to track water movement is brilliant, particularly in the case offloods. Perhaps someday every coastal city will even have similar units mounted just on-shore at beaches, to be swept outto sea in the event of a tsunami or tidal wave — such a network could provide immediate data to help track where the wateris going.
