    • Estimating the value of irrigation water in Georgia 

      Spurgeon, Kyle C.; Mullen, Jeffrey D. (Georgia Institute of TechnologyInstitute of Ecology, The University of Georgia, 2005-04)
      In 1999, the state of Georgia imposed a moratorium on the issuance of new irrigation permits in the Flint River Basin, creating scarcity with respect to both access to irrigation water and the amount of water available. A ...
    • Estimating time to achieve groundwater protection standards using exponential decline plots 

      Raymer, John H. (Georgia Institute of TechnologyInstitute of Ecology, The University of Georgia, 2005-04)
      Groundwater concentrations tend to decline exponentially over time and distance due to natural attenuation or remedial actions. Exponential decline plots make use of existing data to empirically predict the time or distance ...
    • The Etowah Habitat Conservation Plan outreach program: a social networks based approach to public participation and stakeholder involvement 

      Gervich, Curt (Georgia Institute of TechnologyInstitute of Ecology, The University of Georgia, 2005-04)

      Providing for residential growth, fostering economic development, and protecting natural resources of coastal lands requires a balance between the built and non-built environment. A variety of factors come into play, ...
    • Evaluating management needs of Lake Blackshear, Georgia 

      Lebo, M. E.; Cofer, Harland E., Jr.; Tietjen, William L.; Williams, P. Y.; Partridge, D. (Georgia Institute of TechnologyInstitute of Ecology, The University of Georgia, 2005-04)
      Lake Blackshear has been characterized for three decades as eutrophic due to high nutrients and low light penetration (i.e. Secchi depth). However, algal biomass and diversity metrics in the reservoir indicate a lower ...
