项目摘要

Like many cities in semi-arid regions, Los Angeles relies on extensive, centralized redistribution projects for its water supply. Water is transported hundreds of kilometers to support agricultural and urban activities in southern California; however, allocations from remote sources have been declining due to drought, over-extractions, and competing water needs. Increasingly, local governments and water districts are relying on local water sources within the southern California coastal areas including local groundwater, rainwater capture, conservation measures, and recycled water sources. Yet, these resources are managed by a complex set of agencies and water districts with different structures, histories, and priorities, but which often access similar water resources. In addition, the jurisdictions of different water management institutions rarely correspond to watershed and other hydrologic boundaries, such that the connectivities of the socio-political system and the connectivities of the ecohydrologic system present a set of very complex networks for water management. This project will focus on understanding the coupled ecohydrologic and decision-making processes that determine the availability of local water resources in southern California, with the goal of addressing the questions 1) What is the current structure of local groundwater, wastewater, and stormwater management? 2) What are the ecohydrologic constraints on local groundwater and rainwater resources? 3) What is the regional water balance? 4) What are the overlaps and disconnects between the ecohydrologic and decision-making domains? 5) What are feasible targets for conservation given our understanding of biophysical, technological, political, and fiscal constraints? 6) How are these impacted by scenarios of future climate change? To address these issues, this project will draw on extensive existing datasets from previous research as well as public utility and agency data to: model the local water balance and groundwater flows; analyze the structure of local water management institutions; compare and contrast the ecohydrologic and political boundaries and constraints on local water resources; evaluate the vulnerabilities of the ecohydrologic and decision-making components of the local water system to climate, fiscal austerity and land use change; and utilize modeling and decision-making tools to evaluate proposed best practices.This project addresses the most critical issues for water sustainability in the region, many of which involve decreasing southern California's reliance on imported water. To do this, the linkages and mismatches between the natural and human components of the water system must be analyzed. The project will directly evaluate the decision-making tools currently used by local agencies and NGOs to plan groundwater infiltration projects. It will also integrate research datasets with other public and published local information about water consumption and end uses, outdoor landscaping and species specific water use, and current information about best management practices (BMPs) for Los Angeles. These will be evaluated relative to institutional and political constraints such as resistance to maintaining existing infrastructure (due to costs) and funding new initiatives. There will be stakeholder involvement in direct meetings and in a publicly available data repository. Stakeholder partners will form a Technical Advisory Board to provide input on usable data products for local applications. In collaboration with students and a post-doctoral researcher, a central website for project datasets and results will be developed, and data services that are responsive to the needs of the Technical Advisory Board will be provided, including reports and synthetic analyses. The project will engage local students at the high school, undergraduate, and graduate levels as well as in K-12 teacher training activities at the participating institutions and outreach activities of local NGOs. Through a subcontract with the local grassroots organization Urban Semillas, the project will incorporate the results of the research into "Agua University," a program for underserved and minority high school students in Los Angeles. Finally, the project will partner with the non-profit organization TreePeople to enhance their outreach and education facility focused on water infiltration, conservation, and quality.
像许多半干旱地区的城市一样,洛杉矶依赖于广泛的、集中的再分配项目来供水。水被输送数百公里,以支持加州南部的农业和城市活动;然而,由于干旱、过度开采和竞争性水需求,来自偏远地区的分配一直在下降。 越来越多的地方政府和水区依赖于南加州沿海地区的当地水源,包括当地地下水、雨水收集、保护措施和再生水源。 然而,这些资源是由一套复杂的机构和水区管理的,它们具有不同的结构、历史和优先事项,但往往获得类似的水资源。 此外,不同水管理机构的管辖范围很少与流域和其他水文边界相对应,因此,社会政治系统的连通性和生态水文系统的连通性构成了一套非常复杂的水管理网络。该项目将侧重于了解耦合的生态水文和决策过程,决定了当地水资源的可用性在南加州,解决问题的目标1)是什么地方地下水,废水和雨水管理的当前结构?2)当地地下水和雨水资源的生态水文限制是什么?3)什么是区域水平衡?4)生态水文学和决策领域之间的重叠和脱节是什么?5)鉴于我们对生物物理、技术、政治和财政限制的理解,什么是可行的保护目标? 6)未来气候变化的情景如何影响这些?为解决这些问题,本项目将利用以往研究的大量现有数据集以及公用事业和机构的数据:建立当地水平衡和地下水流模型;分析当地水管理机构的结构;比较和对比生态水文和政治边界以及对当地水资源的限制;评估当地水系统的生态水文和决策组成部分对气候、财政紧缩和土地使用变化的脆弱性;并利用建模和决策工具来评估拟议的最佳做法。该项目解决了该地区水资源可持续性的最关键问题,其中许多涉及减少南加州对进口水的依赖。为此,必须分析水系统的自然和人类组成部分之间的联系和不匹配。该项目将直接评估当地机构和非政府组织目前用于规划地下水渗透项目的决策工具。它还将整合研究数据集与其他公共和出版的有关水消费和最终用途,户外景观和物种特定用水的本地信息,以及有关洛杉矶最佳管理实践(BMPs)的当前信息。 将根据体制和政治制约因素,如维护现有基础设施(由于成本)和资助新举措的阻力,对这些措施进行评估。 利益攸关方将参与直接会议和公开数据储存库。 利益攸关方合作伙伴将组成一个技术咨询委员会,就可用于当地应用的数据产品提供投入。将与学生和一名博士后研究人员合作,开发一个项目数据集和成果的中央网站,并提供满足技术咨询委员会需求的数据服务,包括报告和综合分析。 该项目将使当地高中、本科和研究生参与,并在参与机构和当地非政府组织的外联活动中参与K-12教师培训活动。 通过与当地基层组织Urban Semillas的合作,该项目将把研究结果纳入“Agua大学”,这是一个为洛杉矶服务不足和少数民族高中生提供的项目。最后,该项目将与非营利组织TreePeople合作,加强他们的宣传和教育设施,重点是水渗透,保护和质量。
