AB: This NSF WATERS Test Bed Site is focused on describing and understanding fundamental hydrologic processes to develop first-order models to link time/space scales of forcing/response in snow dominated watersheds. Our work places emphasis on fundamental processes to understand recent hydrologic trends in the context of historical and pre-historical natural variability. Our efforts include development of data and tools for formatting and archiving, statistical and time series analysis, assessment of snow cover and other hydrologic variables, and integration of remote sensing data which are suitable for mountain landscapes such as the northern Rockies. A second concentration of the Test Bed is to elucidate the links between snow cover, runoff and climate within several "un-altered" watersheds, nested in scale and spanning a steep climate gradient. A third focus is the comparison between the effects of direct human disturbance (water diversion, storage, land use, etc.) and larger- scale forcing (weather patterns, global warming and climate change) within the context of natural variability. Finally, we are building a complete digital watershed with climatologic and hydrologic data meshed with water and land use data in the basin-wide physiographic and ecologic context. Our aim is to develop a strong physical foundation for continuing the WATERS network concepts into the future and over the entire headwaters of the Columbia and Missouri Rivers.
