REALM for Shallow Water Equations in complex geometries

ANAG and the California Department of Water Resources  are collaborating on an open-source hydrodynamic, transport, and particle tracking model (REALM). Estuary systems of bays and channels comprise our problem domains, over which we discretize the shallow water equations. These equations represent the conservation of mass and momentum in one and two dimensions, including the effects of varying bathymetry and source terms. When completed, REALM will contribute to controversial water-policy debates in California through estimates of salinity, transport of pollutants, and the survival of young fish.

About Berkeley Lab

Founded in 1931 on the belief that the biggest scientific challenges are best addressed by teams, Lawrence Berkeley National Laboratory and its scientists have been recognized with 16 Nobel Prizes. Today, Berkeley Lab researchers develop sustainable energy and environmental solutions, create useful new materials, advance the frontiers of computing, and probe the mysteries of life, matter, and the universe. Scientists from around the world rely on the Lab’s facilities for their own discovery science. Berkeley Lab is a multiprogram national laboratory, managed by the University of California for the U.S. Department of Energy’s Office of Science.

DOE’s Office of Science is the single largest supporter of basic research in the physical sciences in the United States, and is working to address some of the most pressing challenges of our time. For more information, please visit
