Gerald Orlob -- UC Davis professor emeritus of civil and environmental engineering, (916) 752-1424, gtorlob@ucdavis.edu.An expert in mathematical modeling of surface water systems, Orlob has developed several of the models now used by state and federal water agencies to evaluate such issues as alternatives for meeting state water supply and water-quality problems and determining the amount of water available for environmental protection. Recent work on the bay-delta system includes salinity changes in the San Joaquin River drainage, temperature modeling of the Sacramento River system, and water-quality issues related to threatened and endangered species, in particular the striped bass and salmon. Orlob and his students are working on a new generation of models with enhanced graphics for an easier grasp of complex information, as well as integrating multiple-stress effects on ecosystems into the models. Orlob served as a technical adviser on water supply to the governor's Bay-Delta Oversight Committee (BDOC).
