This data release provides the data that support the findings in "Characterizing groundwater and surface-water interaction using hydrograph-separation techniques and groundwater-level data throughout the Mississippi Delta" by Killian and others (2019). This child item for the Generalized Additive Model includes GAMobs_0410_error data and metadata with the grid node coordinates in North American Datum of 1983 (NAD 83) and results, including error estimates for the Generalized Additive Model (GAM) used to estimate the difference in groundwater altitudes relative to NAD 83 for April 10th of 1980 and April 10th of 2016. The paper associated with the data release quantifies the spatial and temporal changes in baseflow...
This data release provides the data that support the findings in "Characterizing groundwater and surface-water interaction using hydrograph-separation techniques and groundwater-level data throughout the Mississippi Delta" by Killian and others (2019). This child item includes the baseflow_est data and metadata that contain daily mean streamflow data provided by the U.S. Geological Survey (USGS) and the U.S. Army Corps of Engineers (USACE), as well as estimated daily mean streamflow records for any missing data and the hydrograph-separation and trends analyses results for the five selected sites output by the USGS Groundwater Toolbox (https://water.usgs.gov/ogw/gwtoolbox/). The paper associated with the data release...
