My research interests lie in the broad areas of forestry, hydrology, and transportation. More specifically I am interested in what occurs when and where these spheres meet. I study the influence of land management activities such as road construction and use, forest harvesting or vegetation removal, and oil and gas exploration, on stream water quality. Topics include:
- Sediment production from heavy use of low-volume roads
- Unbound aggregate road design for improved environmental performance
- Open channel hydraulics and stream crossing design
- Water quality impacts from urban streamside vegetation removal
- Implementation of best management practices for forest roads
