本文采用经济工程优化模型，探讨供水方案的环境恢复的科罗拉多河三角洲，墨西哥。潜在的水源包括通过水市场、废水再利用和来自美国的额外科罗拉多河流量减少当地农业和城市用水。对于这些替代方案，优化模型估计经营和缺水成本，缺水量，和边际经济成本的环境流量和价值的额外的科罗拉多河流量从美国在一系列所需的三角洲环境流量。农业和城市用水的经济价值估计两个辅助模型。研究结果为恢复活动提供了经济上有前途的供水。量化农业和城市经济估值与环境流量之间的权衡，为决策者量化其环境流量估值提供了一个框架。该模型还提供了一个框架，用于在信息可用时整合系统的其他知识。
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 alternatives, the optimization model estimates operating and water scarcity costs, water scarcity volumes, and marginal economic costs of environmental flows and values of additional Colorado River flows from the United States over a range of required delta environmental flows. Economic values for agricultural and urban water uses were estimated by two ancillary models. The results provide insights into economically promising water supplies for restoration activities. Quantifying the trade-off between agricultural and urban economic valuation and environmental flows provides a framework for decision makers to quantify their valuation of environmental flows. The model also provides a framework for integrating additional knowledge of the system as information becomes available.
