世界各地的地下水管理政策越来越注重保护依赖地下水的生态系统以及相关的人类利用和价值。这包括与天然泉水流量相关的生态系统利用和农业系统利用。然而，在平衡人类地下水使用和与泉水流量相关的生态需水方面，实用工具的实例很少。利用模拟优化框架，我们将泉水流量约束直接纳入对可持续开采量的分析中，以便在夏威夷州实施地下水政策。我们在瓦胡岛的应用案例是一个依赖泉水流量的西洋菜农场，它具有历史、文化和生态意义。这项研究为夏威夷的决策者提供了有关地下水抽取和泉水流量之间权衡的信息，泉水流量与多种效益相关，包括符合成文的州有益利用保护规定的历史和文化价值。由于这种权衡是在夏威夷实施可持续开采量政策的重要一步，最后我们讨论了使夏威夷的地下水政策更接近完全纳入州水法的公共信托原则所必需的进一步概念和技术发展。
Groundwater management policy around the world increasingly seeks to protect groundwater-dependent ecosystems and associated human uses and values. This includes uses of ecosystems and agricultural systems linked to natural spring discharge. Yet, there are few examples of practical tools to balance human groundwater use with ecological water demand related to spring discharge. Using a simulation optimization framework, we directly incorporate a spring discharge constraint into the analysis of sustainable yield for operationalizing groundwater policy in the state of Hawai‘i. Our application on the island of O‘ahu is a spring discharge-dependent watercress farm with historical, cultural, and ecological significance. This research provides decision-makers in Hawai‘i with information regarding the trade-off between groundwater pumping and spring discharge, which is connected to multiple benefits, including historical and cultural values in line with codified state beneficial use protections. Because this trade-off provides an important step in operationalizing sustainable yield policy in Hawai‘i, we conclude by discussing further conceptual and technical developments necessary to move groundwater policy in Hawai‘i closer to full incorporation of the public trust principles of the state water code.
