The Need for Headwater Protection and High-Elevation Stormwater Controls

Headwater streams and wetland areas are the birthplace of our surface water resources.  They constitute the greatest percentage of total stream length in a river system.  They are vitally important for providing clean and cold water, habitat, and flood control; however, they can only provide such services if they are protected from disturbance.  Headwater streams offer the greatest opportunity for interaction between water and land; and it is with this interaction that numerous biological, chemical, and physical processes are constantly occurring to clean stormwater runoff.  These are the processes which are responsible for maintaining water quality downstream. I am a [...]

Filtering Runoff Phosphorus with a Phosphorus Removal Structure

Dr. Josh McGrath (University of Maryland) and I have started a blog on the step-by-step design and construction of a phosphorus removal structure, which is essentially a large landscape filter.  The motivation for this technology is that phosphorus is typically the most limiting nutrient in surface waters, and therefore eutrophication. Location of the blog: http://p-structure.blogspot.com The purpose of that blog is to provide a case-study example of designing and constructing a phosphorus (P) removal structure, step by step. A P removal structure is intended to filter dissolved P (DP) from runoff using industrial by-products, before the runoff reaches a surface water [...]
