      Fecal coliform is the most frequently listed stream impairment on the Georgia 303(d) list, the listing of streams and associated water quality impairments required under the US Clean Water Act. In many instances, the ...
    • Federal-State Environmental Agency Relationships: A Weak Confederacy 

      Haines, Douglas P. (Georgia Institute of TechnologyInstitute of Ecology, 1999-03)
      The relationship between state and federal environmental agencies has changed significantly over the last several years as concepts of "devolution" and increased local control have gained increasing political force. The ...
    • Field evaluation of compost and mulches for erosion control 

      Risse, L. Mark; Faucette, L. Britt; Gaskin, Julia W.; Jordan, Carl F.; Cabrera, Miguel L.; West, Larry T. (Georgia Institute of TechnologyInstitute of Ecology, The University of Georgia, 2005-04)
      Soil erosion is one of the largest contributors to nonpoint source pollution in Georgia. The use of surface applied organic amendments has been shown to reduce runoff and erosion and improve vegetative establishment on ...
    • Field monitoring of bridge scour at four bridge sites in Georgia 

      Gotvald, Anthony J. (Georgia Institute of TechnologyInstitute of Ecology, 2003-04)
      Erosion of the streambed near bridge foundations is often referred to as “bridge scour.” Bridge scour is caused by the interaction between tur-bulent flows induced by bridge structures and the streambed. These turbulent ...
    • Field Monitoring of Bridge Scour in Georgia 

      Gotvald, Anthony J.; Landers, Mark N. (Georgia Institute of TechnologyInstitute of Ecology, 2001-03)
      Scour or erosion of the streambed near the foundations of a bridge is often referred to as "bridge scour." Bridge scour is caused by the interaction between turbulent flows induced by bridge structures and the ...
    • Field Scale Evaluation of Crop Residue Cover Distribution Using Airborne and Satellite Remote Sensing 

      Sullivan, Dana; Fulmer, J. L.; Strickland, Tim; Masters, Mark H.; Yao, Huaming (Georgia Institute of Technology, 2007-03)
      Conservation tillage adoption has been associated with sustainable agricultural practices and linked with increased plant available water content in some regions. However, rapid and spatially accurate field scale assessments ...
    • Field Testing Pesticide Transport Models at a Cooperative Test Site Near Plains, Georgia 

      Smith, Charles N.; Brown, David S.; Parrish, Rudolph S.; Asmussen, Loris E.; Leonard, Ralph A.; Hicks, D. Woodrow; Payne, William R.; Fletcher, R. Shaw (Georgia Institute of TechnologyInstitute of Natural Resources, 1991)
      Leaching of pesticides is a potential problem in the major agricultural production areas of southern Georgia where sandy soils are predominant. Compounds used on crops such as peanuts, corn, and soybeans are of particular ...
    • A Field Trial using Low Application Rates of Polyacrylamide (PAM) to Reduce Soil Erosion from Disturbed Piedmont Soils 

      Glazer, Rebekah L.; Markewitz, Daniel (Georgia Institute of TechnologyInstitute of Ecology, 2001-03)
      Land disturbing activities during urban and suburban development are increasing soil erosion and leading to increasing turbidity in surface waters of Georgia. In two field trials, we tested the efficacy of low applications ...
    • Field Trials of Alum Amendment of Broiler Litter to Reduce Soluble Phosphorus 

      Worley, John W.; Cabrera, Miguel L. (Georgia Institute of TechnologyInstitute of Ecology, 1999-03)
      Aluminum sulfate (alum) has been demonstrated to reduce ventilation and heating requirements by lowering pH and thus reducing ammonia release from broiler litter during brooding of broiler chickens raised on previously ...
    • Field vs. Laboratory Permeability Estimates 

      Rasmussen, Todd C. (Georgia Institute of TechnologyInstitute of Natural Resources, 1993-04)
