Abstract

In mountain environments, spatial and temporal patterns of snow accumulation and melt are dominant controls on hydrologic responses to climate change. In this paper, we develop a simple conceptual model that links the timing of peak snowmelt with geologically mediated differences in rate of streamflow recession. This model demonstrates that within the western United States, spatial differences in subsurface drainage rates can exacerbate summer streamflow losses associated with diminishing snowpacks.
