Dataset for: Net land gain or loss for two Mississippi River diversions: Caernarvon and Davis Pond

Two sets of percent land data in flow paths and adjacent reference areas of two diversions in Louisiana (Davis Pond and Caernarvon) were calculated from two sources of public satellite imagery data (see Methods) from 1985-2014 in order to test the hypothesis that river diversions stimulate land building. Additionally, data from another public source (see Methods) was compiled as input for a BACI (before-after control-impact) analysis. Land acreage and percent land data were calculated for 1985 to 2016, with values being designated as being inside or outside of the flow path of the Caernarvon diversion. This dataset supports the publication by Turner, R. Eugene, Michael Layne, Yu Mo, and Erick M. Swenson. 2019. Net land gain or loss for two Mississippi River diversions: Caernarvon and Davis Pond.
