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)
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)
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)
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)
[1] The potential and limitations of conjunctive use of surface and groundwater are explored for southern California's water supply system. An economic-engineering network flow optimization model, CALVIN, is used to analyze the economic and reliability benefits from different conjunctive use alternatives. Flexible management of additional conjunctive use(More)
Economical integration of permanent and emergency flood control options is a long-standing problem in water resources planning and management. A two-stage linear programming formulation of this problem is proposed and demonstrated which provides an explicit economic basis for developing integrated floodplain management plans. The approach minimizes the(More)
The old and useful paradigm used by water resource engineers that hydrology in a given place is stationary, and hence it is sufficient to look into the past to plan for the future, doesn't hold any more according to climate change projections. This becomes especially true in snow-dominated regions like California where not only the magnitude but also the(More)
