Population growth, shifting land uses, and climate variability are altering the magnitude and timing of water fluxes, stores, and availability in the arid Intermountain Western U.S. These alterations are driven by coupled human-natural system interactions at spatial scales ranging from farm plots and buildings to entire river basins and temporal scales from seconds to centuries. These pressures produce interconnected responses in atmospheric, surface,and subsurface processes, threatening the sustainability of natural water systems supporting fragile ecosystems and the resiliency of constructed water systems on which tens of millions of people depend.
CI-WATER has enabled a consortium of Utah and Wyoming researchers to acquire and develop the hardware and software cyberinfrastructure (CI) required to create large-scale, high-resolution computational water resources models. The models are designed to perform comprehensive examinations of integrated system behavior through physically-based, data-driven simulation.
