Artes: Modeling Water Resources Management in Los Angeles

Modeling Integrated Water Resources in Los Angeles

"The history of the growth and development of Los Angeles... reveals its conscious use of water as a tool to build the 'great metropolis of the Pacific'"
-- Vincent Ostrom, 1962

Welcome to the repository for Artes, an integrated model of urban water resources in metropolitan Los Angeles (LA). It evaluates the potential for enhanced local water supplies in LA.

Los Angeles (LA) relies on large infrastructure systems that import water over hundreds of miles. Communities in LA face a future of increased water scarcity and reduced imports. Hundreds of water agencies serve nearly 10 million people within the county. Laws, institutions, and hydrogeology all influence the capacity of these agencies to adapt to future changes. To analyze the potential for future local water reliance and resilience, we used systems analysis of urban water management in metropolitan LA County to assess opportunities for increasing local water reliance. We developed a detailed network flow model to investigate management tradeoffs across engineered, social, and environmental systems.

The model and its underlying data have been used to produce 11 peer-reviewed studies. Model outputs and methods have also informed numerous regional studies and plans, including:
- the LA County Sustainability Plan,
- UCLA's Los Angeles Environmental Report Card,
- the Santa Monica Groundwater Sustainability Plan's evaluation of integrated basin management options,
- California's Fourth Climate Change Assessment (Los Angeles Regional section).

The model is a product of the California Center for Sustainable Communities at UCLA.

构建洛杉矶综合水资源模型

《洛杉矶增长与发展的历史……揭示了其有意识地利用水资源作为构建“太平洋上的伟大都会”工具的自觉行为。” —— 文森特·奥斯特罗姆，1962年

欢迎来到Artes的存储库，该模型是洛杉矶大都市区（LA）城市水资源的综合模型。它评估了洛杉矶增强当地水资源供应的潜力。

洛杉矶（LA）依赖大型基础设施系统，从数百英里之外进口水资源。LA的社区面临着未来水资源日益稀缺和进口量减少的挑战。数百个水机构服务于该县近1000万人。法律、制度和水文地质条件均影响着这些机构适应未来变化的能力。为了分析未来对当地水资源的依赖性和弹性，我们利用了洛杉矶大都市区城市水管理的系统分析方法来评估提高当地水资源依赖性的机会。我们开发了一个详细的网络流量模型，以调查在工程、社会和环境系统之间的管理权衡。

该模型及其基础数据已被用于产生11篇同行评审的研究。模型输出和方法还影响了众多区域研究和计划，包括：
- 洛杉矶县可持续发展计划
- 加州大学洛杉矶分校的洛杉矶环境报告卡
- 圣莫尼卡地下水可持续发展计划对综合流域管理选项的评估
- 加利福尼亚州的第四次气候变化评估（洛杉矶区域部分）。

该模型是加州大学洛杉矶分校可持续社区中心的成果。
