Summary & Purpose

Geologic, geomorphic, and climatic factors have been hypothesized to influence stream drying patterns, but hydrologists struggle to explain spatiotemporal patterns of drying. Few hydrologists have isolated the role that vegetation plays in controlling the timing and location of stream drying. We continuously measured the presence and absence of streamflow at twenty-five locations at Murphy Creek within the Reynolds Creek Experimental Watershed and Critical Zone Observatory. In addition to streamflow observations, we modeled evapotranspiration and calculated the normalized vegetation difference index (NDVI) at each of the same twenty-five locations. We found that evapotranspiration impacts the timing of stream drying and that NDVI reflects streamflow status and has potential to be used to predict spatiotemporal stream drying patterns.
