Brent R. Johnson

My research generally focuses on developing and refining assessment methods for both headwater streams and large rivers. This includes developing rapid measures of ecosystem function, as well as novel techniques for determining how headwaters can infl uence quality of downstream waterbodies. My current work specifi cally focuses on impacts from Appalachian coal mining and also attempts to address science needs resulting from recent litigation dealing with headwaters and isolated wetlands.
