Affiliate Professor, Department of Plant Science and Landscape Architecture
Civil and Environmental Engineering
1151 Glenn L. Martin Hall


  • B.S., University of Delaware, 1984
  • M.C.E., University of Delaware, 1986
  • Ph.D., University of Delaware, 1989

  • Water quality and physiochemical treatment processes
  • Urban storm water quality characterization and treatment
  • Fundamental and applied research on stormwater control measures
  • Development of media and designs for enhanced stormwater quality improverment

  • Enhancing phosphorous removal in permeable paving

    Principal Investigator(s): Davis, Allen P.

    This project will provide research and development support for a sub-base material to be used with PaverGuide, a base material for permeable paving. This paving reduces sediment, nitrogen, and phosphorus runoff into the Chesapeake Bay. Specific emphasis is on phosphorus removal. More information about this project is available online.
  • Evaluation of compost addition to stormwater control measure (SCM) performance

    Principal Investigator(s): Davis, Allen P.

    Recent state law encourages the use of compost throughout the landscape. This project evaluates the possibility of using compost in bioretention and submerged gravel wetland stormwater control measures. Emphasis is on understanding, quantifying, and minimizing leaching of nitrogen and phosphorus from the compost. More information about this project is available online.
  • LIDMIX Stormwater Treatment System

Principal Investigator(s): Davis, Allen P.


  • Use of Compost to Establish Permanent Vegetation

Principal Investigator(s): Davis, Allen P., & Aydilek, Ahmet
