Global Rapid Indicator Mapping System (Global-RIMS)
Supporting Water Cycle Science and Water Resource ManagementHydrology is at an important crossroads. As articulated in several "grand challenge" documents, we’ve made great progress in process-level understanding at plot, hillslope, and small catchment scales, but our capacity to pass to the next horizon—to understand inherent variability in the water cycle, predictability, human dimensions, and links to biogeochemical cycling over broader domains—requires a major reformulation of our thinking and a purposeful move toward synthesis and systematic observation.
