Waterbodies that exhibit persistent water and lack trees within the majority of its area are defined as open waterbodies by the National Hydrography Dataset (NHD, USGS, 2011). The data presented here were created to determine the volume of water for open waterbodies on the floodplain of the Atchafalaya River Basin. Open waterbodies and their surficial geometry were identified using a geographic information system (GIS) shapefile acquired from the NHD. The spatial coverage was clipped to areas within the Atchafalaya Basin Floodway System area of interest. Bed elevations of a representative set of channels were determined from bathymetric surveys conducted 2014-2017 during high river stages by the U.S. Geological...

Data on changing hydrogeomorphic characteristics along river gradients from nontidal through tidal freshwater to oligohaline reaches along the Mattaponi and Pamunkey Rivers, Virginia. Shapefile data include location and elevation profiles of the river valleys along multiple digital cross-sections from lidar digital elevation models, satellite visible imagery, and geographic information system analysis. These data were used to help interpret fundamental changes in regime along rivers as they transition from watersheds into the coastal zone.

Data were retrieved from a long-term data set for analyses of the relationship between residence time of flood waters with dissolved oxygen concentration collected as part of a long-term water quality monitoring program from 1 January 2000 through 31 December 2010 in East Grand Lake/Flat Lake Water Management Unit in the Atchafalaya River Floodway System. Dissolved oxygen data were collected biweekly by Louisiana State University, Renewable Natural Resources Dept (by personnel of Bill Kelso and Michael Kaller) at permanently flooded and floodplain locations as accessible during the annual flood cycle. We limited our analyses to the latter stages of the annual flood pulse, based on results of previous research indicating...
