The scientific mission of the HydroEcological Engineering Advanced Decision Support (HEADS) research group within the Earth Sciences Division at Berkeley National Laboratory is to develop techniques, technologies and computer-based decision support systems to enhance environmental monitoring, modeling and management.

HEADS comprises civil, environmental and agricultural engineers, earth scientists, microbiologists and computer scientists who work cooperatively with each other and with both state and federal resource agencies within California and internationally to develop the linkage between environmental science and the environmental resource management decision making process. Current research and development projects are listed on this website and are centered around salt, selenium and dissolved oxygen management in the San Joaquin Basin of California. The San Joaquin Valley of California is one of the productive agricultural regions in the world and is also one of the most complex from a hydrological and ecological perspective. Current project cooperators and research funding agencies include the US Bureau of Reclamation, the California Department of Water Resources, Grassland Water District, Panoche Water District, the CALFED Bay-Delta Program, University of California, Berkeley and the University of California, Los Angeles.
