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)
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)
This paper uses simple hydro-economic optimization to investigate a wide range of regional water system management options for northern Baja California, Mexico. Hydro-economic optimization models, even with parsimonious model formulations, enable investigation of promising water management portfolios for supplying water to agricultural, environmental and(More)
ii iii Executive Summary ES-1. Introduction This document provides guidance for conducting economic and financial analyses of water recycling projects. Proponents of a water recycling project may benefit from the methods described in this document in applying for state and federal grants and loans, as well as for internal evaluations of the desirability and(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)
