Evaluating Institutional Alternatives for Managing an Interrelated Stream‐Aquifer System
针对科罗拉多州南普拉特河地区地下水开采影响河流用水的问题，建立水文-法律-农民决策模拟模型，评估不同管理制度方案，发现“增补计划”在正常和干旱条件下均能提高净收入并保护河流用水者优先权。
Abstract Farmers relying on the South Platte River in northeastern Colorado for irrigation water have been found to be adversely affected by pumping from a groundwater deposit associated with the river. A simulation model of the hydrologic‐legal‐farmer decision system is developed and employed to analyze several institutional alternatives for managing the system. The “augmentation plan” approach recently developed by the state was shown to yield highest net incomes under both normal water supply and drought scenarios while protecting the prior rights of river water users. Anticipated opportunity costs of ground water use are internalized into pumpers' decisions.
