AI’s rapid growth is driving digital infrastructure expansion and increasing both cooling water use and electricity-related water use. These impacts extend beyond local watersheds via virtual water flows and grid-mediated demand. This session treats digital infrastructure as an emerging hydrological forcing and explores how AI-driven growth alters water–energy–carbon linkages via cooling demand, electricity-related water use, and grid-varying loads, with telecoupled impacts across regions under climate change. We welcome contributions on, but not limited to: (1) Remote sensing, inventory development, virtual water accounting and cross-regional footprint attribution; (2) Climate-change-driven risks and resilience of digital expansion; (3) Modeling direct, indirect, and telecoupled impacts of digital infrastructure on hydrological systems; (4) Optimization and coupled modeling of data centers or other digital infrastructure within integrated water–energy–carbon systems; (5) Policy frameworks, adaptive technologies, and socio-economic strategies to minimize hydrologic disturbance and inter-sectoral water conflicts.
