科罗拉多河流域是一个水文河网,主要将科罗拉多州和怀俄明州山区的雨雪径流引导至墨西哥的科罗拉多河三角洲。上个世纪,为了应对全流域的水资源短缺,美国七个州和墨西哥的利益相关者之间达成了法律协议,来自河流主干用户的水文流量已被重新分配给初级水权持有者。市政当局、企业、农民和家庭利用科罗拉多河的水来生产和交易有价值的、水衍生的商品和服务,通过不断适应、无边界的经济河网,提供间接获取“虚拟”科罗拉多河水的途径,有效地重新分配水。我们将科罗拉多河流域概念化为一个由相互依赖的自然流网络、直接(基础设施)流网络和间接(虚拟)流网络组成的多重网络。通过这种重构,我们量化了干旱应急计划 (DCP) 对下游流域各州的总体水文影响。通过 DCP 每减少 1 Mm3 的水量,亚利桑那州、内华达州和加利福尼亚州分别会额外损失 0.42–0.43 Mm3、0.33–0.51 Mm3 和 1.06–1.10 Mm3 的虚拟水流量。因此,DCP 将要求亚利桑那州、内华达州和南加州调整用水方式,减少对科罗拉多河水的直接和间接消耗,并在该流域之外寻找更多间接水源。
The Colorado River Basin is a hydrologic river network that directs runoff from rain and snow falling on mountains, primarily in Colorado and Wyoming, to the Colorado River Delta in Mexico. Over the last century, in response to basin‐wide water shortages, legal agreements between stakeholders in seven U.S. states and Mexico, hydrologic flows from users on the main stem of the river have been reallocated to junior water rights holders. Municipalities, businesses, farmers, and households utilize the Colorado River water to produce and trade valuable, water‐derived goods and services, which effectively reallocates water through a continually adapting, boundary‐free economic river network providing indirect access to "virtual" Colorado River water. We conceptualize the Colorado River Basin as a multiplex network comprised of interdependent natural flow networks, direct (infrastructural) flow networks, and indirect (virtual) flow networks. Using this reframing, we quantify the total hydrosocial impact of the Drought Contingency Plan (DCP) on Lower Basin states. For each Mm3of water reduced through the DCP, Arizona, Nevada, and California lose an additional 0.42–0.43 Mm3, 0.33–0.51 Mm3, and 1.06–1.10 Mm3of virtual water flow, respectively. Hence, the DCP will require Arizona, Nevada, and Southern California to restructure how they use water, relying less on direct and indirect consumption of the Colorado River water and finding more indirect water sources outside that basin.
