Evaluating controls on nutrient retention and export in wide and narrow valley segments of a mountain river corridor

Publications Posted on: October 04, 2018
Over the past few decades, nitrate-nitrogen (NO3-N) concentrations have increased within streams of the central Rockies, a pattern linked to regional N deposition trends. As NO3-N concentrations increase, in-stream biological demand may become saturated and stream N export may increase. In mountain landscapes, streams generally flow through steep, narrow valleys with limited riparian area and strong stream-hillslope connectivity.

The legacy of a severe wildfire on stream nitrogen and carbon in headwater catchments

Publications Posted on: September 25, 2018
Large, high-severity wildfires alter the physical and biological conditions that determine how catchments retain and release nutrients and regulate streamwater quality. The short-term water quality impacts of severe wildfire are often dramatic, but the longer-term responses may better reflect terrestrial and aquatic ecosystem recovery.
