Next generation of water monitoring technology

Narrator:        This is Science Today. The next generation of water monitoring technology is being tested in California's Sacramento-San Joaquin River Delta. The Floating Sensor Network, developed by a team of engineers at the University of California, Berkeley, is comprised of over 100 mobile sensors that use GPS-enabled smartphones to provide researchers with real-time data in hard-to-map waterways. Graduate student Andrew Tinka explains their floating network differs from the usual stationary sensors.

Tinka:             Floating sensors allow us to trace the movement of packets of water, through the system, so that we can understand where the salt water goes and where the freshwater goes, how they meet, how they mix and where they end up.

Narrator:        The goal of this experiment is to provide water managers a better tool to come up with better solutions.

Tinka:             We need to know where the water goes and we need to know how it carries things through the Delta, how it carries salt water, how it carries pollution. We need to know these things so we can make environmental management decisions about where the water should go and how we can manage the Delta.
