英文摘要	Water stress in many regions is a consequence of precipitation that is spatially and temporally distant and the cumulative effects of withdrawals, inter-basin transfers, and reservoirs. Most maps of “water risk” do not account for the role of infrastructure and rely on local runoff metrics, which may be a poor proxy for experienced water stress. We present a new spatial and multi-sectoral optimization model of resource networks, applied here to water resources in the United States. The model, AWASH, includes a detailed representation of surface water and reservoirs, and relates water risk directly to failures to meet water demand as a function of climate. We find that considering the role of water conveyance and storage infrastructure in managing supply leads to a radically different picture of water risk, with substantial reductions due to both types of infrastructure – up to 60% reduction in risk due to conveyance and 38% due to storage. This highlights the importance of accounting of the role of infrastructure in national climate risk assessment and adaptation strategies. © 2022 The Author(s)
