Power system reliability is sensitive to climate-driven variations in both energy demand and water availability, yet the combined effect of these impacts rarely evaluated. Here we show that climate change on loads hydropower generation may have a transformative nature seasonality power shortfall risk U.S. Pacific Northwest. Under change, potential events occur more readily, but are significantly less severe nature. A seasonal reversal occurs: winter shortfalls eradicated due reduced building...
There are over 52,000 dams in the contiguous US ranging from 0.5 to 243 meters high that collectively hold 600,000 million cubic of water. These structures have dramatically affected river dynamics every major watershed country. While there national datasets document dam attributes, is no dataset reservoir operations. Here we present a historical inflows, outflows and changes storage for 679 reservoirs across US, called ResOpsUS. All data provided at daily temporal resolution. Temporal...
Abstract Future rates of global groundwater depletion will depend on the economic and environmental viability extracting water from increasingly stressed aquifers. Here we analyze by considering these factors explicitly. Global gridded availability extraction cost data are aggregated to produce nonrenewable resource supply curves for 235 major river basins geopolitical regions. These resources then exposed dynamically generated demands in a fully coupled, multisectoral, simulation. As head...
Abstract. Considerable research effort has recently been directed at improving and operationalising ensemble seasonal streamflow forecasts. Whilst this creates new opportunities for the performance of water resources systems, there may also be associated risks. Here, we explore these potential risks by examining sensitivity forecast value (improvement in system brought about adopting forecasts) to changes skill a range hypothetical reservoir designs with contrasting operating objectives....
Abstract Future changes in climate and socioeconomic systems will drive both the availability use of water resources, leading to evolutions scarcity. The contributions can be quantified individually understand impacts around world, but also combined explore how coevolution energy-water-land affects not only driver behind scarcity changes, human interact tandem alter Here we investigate relative on under Shared Socioeconomic Pathways-Representative Concentration Pathways framework. While...
Abstract. Medium- to long-range forecasts often guide reservoir release decisions support water management objectives, including mitigating flood and drought risks. While there is a burgeoning field of science targeted at improving forecast products associated decision models, data describing how when are applied in practice remain undeveloped. This lack knowledge may prevent hydrological modelers from developing accurate schemes for large-scale, distributed hydrology models that...
Large-scale hydrological and water resource models (LHMs) require storage release schemes to represent flow regulation by reservoirs. Owing a lack of observed reservoir operations, state-of-the-art LHMs deploy generic scheme that may fail local operating behaviors. Here we introduce new dataset bespoke policies for 1,930 reservoirs conterminous United States. The Inferred Storage Targets Release Functions (ISTARF-CONUS) relies on inventory daily operations (ResOpsUS) generate rules 595...
Abstract Drinking water supplies of cities are exposed to potential contamination arising from land use and other anthropogenic activities in local distal source watersheds. Because quality sampling surveys often piecemeal, regionally inconsistent, incomplete with respect unregulated contaminants, the United States lacks a detailed comparison across all its large cities. Here we combine national-scale geospatial datasets hydrologic simulations compute two metrics representing point nonpoint...
Abstract Despite a decade of research into climate change impacts on water resources, the scientific community has delivered relatively few practical methodological developments for integrating uncertainty resources system design. This paper presents an application “decision scaling” methodology assessing performance and asks how such approach might inform planning decisions. The decision scaling method reverses conventional ethos impact assessment by first establishing conditions that would...
Climate change is expected to affect the availability of water for electricity generation, yet propagation climate impacts across a large and diverse power grid remains unexplored. In this study, we evaluate how projected changes in generation at hydroelectric thermal plants coincident propagate locally throughout interconnected western United States. We also whether prospect climate-driven could regional dependencies. Hydrologic simulations derived from three Global Circulation Models...
El Niño Southern Oscillation (ENSO) strongly influences the global climate system, affecting hydrology in many of world's river basins. This raises prospect ENSO-driven variability and regional hydroelectric power generation. Here we study these effects by generating time series production for 1593 hydropower dams, which collectively represent more than half existing installed capacity. The are generated forcing a detailed dam model with monthly-resolution, 20th century inflows—the includes...
Abstract Large‐scale hydrological and water resource models (LHMs) are used increasingly to study the vulnerability of human systems scarcity. These rely on generic reservoir release schemes that often fail capture nuances operations at individual dams. Here we assess whether empirically derived release‐availability functions tailored dams could improve simulation performance an LHM. Seasonally varying, linear piecewise relations specify as a function prevailing storage levels forecasted...
Abstract. This study enhances an existing global hydrological model (GHM), Xanthos, by adding a new water management module that distinguishes between the operational characteristics of irrigation, hydropower, and flood control reservoirs. We remapped reservoirs in Global Reservoir Dam (GRanD) database to 0.5∘ spatial resolution Xanthos so single lumped reservoir exists per grid cell, which yielded 3790 large implemented unique operation rules for each type, based on their primary purposes....
Abstract The Monsoon Asia region is home to ten of the world's biggest rivers, supporting lives 1.7 billion people who rely on streamflow for water, energy, and food. Yet a synthesized understanding multicentennial variability this lacking. To fill gap, we produce first large scale reconstruction over (62 stations in 16 countries, 813 years mean annual flow). In making reconstruction, develop novel, automated, climate‐informed, dynamic framework that skillful most region. We show spatially...
Abstract This paper examines the extent to which regime‐like behavior in streamflow time series impacts reservoir operating policy performance. We begin by incorporating a regime state variable into well‐established stochastic dynamic programming model. then simulate and compare optimized release policies—with without variable—to understand how shifts affect performance terms of meeting water delivery targets. Our optimization approach uses Hidden Markov Model partition small number separate...
This paper explores regional response strategies to potential water scarcity. Using a model of integrated human-earth system dynamics (GCAM), we test wide range alternate demand scenarios explore strategies. We create typology that categorizes countries and basins according their responses in electricity agriculture Three different categories are found. First, little is observed for many because demands do not increase enough Second, the primary adjustments sector (e.g. most Western Europe,...
