      We propose a new approach to stormwater control, which we call The 10-25 Plan. The 10-25 Plan is a stormwater management framework whose goal is to prevent and mitigate the adverse economic and environmental impacts ...
    • Increasing regulatory controls over animal feeding operations to enhance environmental quality 

      Centner, Terence J.; Mullen, Jeffrey D. (Georgia Institute of TechnologyInstitute of Ecology, 2003-04)
      Economies of scale have led to the production of animals at large confined facilities concentrated in selected regions. Such production has been accompanied by environmental problems including the degradation of water ...
    • Watershed assessment through ecological research/farmers active in research 

      Franklin, Dorcas H.; Cabrera, Miguel L.; Steiner, Jean L.; Risse, Larry A.; Risse, L. Mark; Hibbs, Henry E. (Georgia Institute of TechnologyInstitute of Ecology, 2003-04)
      Producers in the Southern Piedmont graze and manage their lands in a variety of ways across watersheds and across individual farms. These land management practices may have an impact on the nitrogen (N) and phosphorus ...

    • Seeing is believing: hands-on tools for education on non-point source pollution 

      Gaskin, Julia W.; Hawkins, Gary L.; Pagan, Tina W.; Risse, L. Mark (Georgia Institute of TechnologyInstitute of Ecology, 2003-04)
      It is sometimes difficult for people to understand that they are contributing to non-point source pollution because it is by definition diffuse and it is difficult to visualize. Over the past several years, the ...
    • Stream Restoration Case Studies in North Carolina 

      Jennings, Gregory D. (Georgia Institute of TechnologyInstitute of Ecology, 2003-04)
      Natural stream functions in many areas of North Carolina are threatened by changes in watershed hydrology and land use, often resulting in unstable streams with poor habitat and water quality. Impacts include eroding ...
