The Center for Information Technology Research in the Interest of Society (CITRIS), Berkeley Lab and its National Energy Research Scientific Computing Center (NERSC), and UC Berkeley's Department of Civil and Environmental Engineering and Department of Electrical Engineering are collaborating to conduct an unprecedented experiment in the area of hydrodynamic monitoring to advance our understanding of water conditions in the Delta. Understanding how the water flows through the Delta on its way to pumping stations and San Francisco Bay is imperative to balance conflicting demands on this critical resource.
