An economic-engineering optimization model of California's major water supply system is presented. The model's development , calibration, limitations, and results are reviewed. The major methodological conclusions are that large-scale water resources optimization models driven by economic objective functions are both possible and practical; deterministic(More)
The ability of California's water supply system to adapt to long-term climatic and demographic changes is examined. Two climate warming and a historical climate scenario are examined with population and land use estimates for the year 2100 using a statewide economic-engineering optimization model of water supply management. Methodologically, the results of(More)
Economically optimal operational changes and adaptations for California's water supply system are examined for a dry form of climate warming (GFDL CM2.1 A2) with year 2050 water demands and land use. Economically adaptive water management for this climate scenario is compared to a similar scenario with the historical climate. The effects of population(More)
High variability in environmental conditions in both space and time once made the upper San Francisco Estuary (the Estuary) highly productive for native biota. Present conditions often discourage native species, providing a rationale for restoring estuarine variability and habitat complexity. Achieving a variable, more complex Estuary requires policies(More)
Office of the Chancellor for providing funding for this study. We are immensely grateful for the technical support provided by the California Department of Water Resources Bay Delta Office on the interaction between the SWAP and the C2VSIM models, in particular to Tara Smith, Tariq Kadir, Emin Dogrul and Charles Brush. We are also indebted to Thomas Harter(More)
Several methods for developing flow prescriptions to support desirable fish species in the Delta are compared. To be useful, flow prescriptions must respond to the changing characteristics of the Delta, including sea level rise, additional flooded islands, changes in water diversions, and new invasive species. Adaptive flow prescriptions for desirable fish(More)
