    • Georgia Riparianism and Irrigation 

      Bowen, Brandon L. (Georgia Institute of TechnologyInstitute of Ecology, 2001-03)
      This paper will discuss the current state of riparian rights in Georgia, particularly in the irrigation context. There will be a discussion of the history of the riparian doctrine, including its origins and application ...
