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)
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)
Keywords: Hydro-economic models Integrated water resource management (IWRM) Systems analysis Water value Water demand s u m m a r y Future water management will shift from building new water supply systems to better operating existing ones. The variation of water values in time and space will increasingly motivate efforts to address water scarcity and(More)
This paper employs an economic-engineering optimization model to explore water supply options for environmental restoration of the Colorado River Delta, Mexico. Potential water sources include reductions in local agricultural and urban water use through water markets, wastewater reuse, and additional Colorado River flows from the United States. For these(More)
This paper describes calibration methods for models of agricultural production and water use in which economic variables can directly interact with hydrologic network models or other biophysical system models. We also describe and demonstrate the use of systematic calibration checks at different stages for efficient debugging of models. The central model is(More)
If abrupt climate change has occurred in the past and may be more likely under human forcing, it is relevant to look at the adaptability of current infrastructure systems to severe conditions of the recent past. Geologic evidence suggests two extreme droughts in California during the last few thousand years, each 120-200 years long, with mean annual(More)

California's water system provides many vital services: supplying clean water for homes, farms, and other businesses; protecting the quality of rivers, lakes, and beaches; preventing loss of life and property from devastating floods; and safeguarding the health and habitat of fish and other wildlife. By some accounts, our water system is in a deep financial(More)
Reversing declines in the populations of native fish in the Sacramento–San Joaquin Delta is a major water policy challenge for California. In choosing a portfolio of management actions to improve conditions for these fish, two considerations are key: the actions' ecological potential to support these species and the costs to those using the Delta's lands(More)
