ABSTRACT

Water stress prompts a durable reduction in water demand under some circumstances. This demand reduction has the potential to alter the benefits and costs of demand- and supply-side alternatives in water supply planning. This paper takes a socio-hydrological approach to assess the implications of this feedback, in the context of Las Vegas, Nevada. This application demonstrates feasibility first by developing and testing a novel model of water salience as a function of proximity to water supply thresholds, and then linking modules to account for feedback between subsystems. Lastly, by comparing this model to a water use scenario model to assess system performance under a range of future conditions and potential responses, this work illustrates the trade-offs between scenarios and the socio-hydrological approach. This model, while specific to Las Vegas, demonstrates a prototypical modeling framework capable of examining water supply–demand interactions by incorporating water stress-driven conservation.

摘要

在某些情况下，缺水会促使水需求持续减少。这种需求减少有可能改变供水规划中需求侧和供应侧替代方案的收益和成本。本文以内华达州拉斯维加斯为背景，采用社会水文方法来评估这种反馈的影响。该应用程序首先通过开发和测试作为接近供水阈值的函数的新的水显着性模型来证明可行性，然后链接模块以考虑子系统之间的反馈。最后，通过将该模型与用水情景模型进行比较，以评估在一系列未来条件和潜在响应下的系统性能，这项工作说明了情景与社会水文方法之间的权衡。这个模型，
