SEAWAT Model of Flow and Chloride Transport in the 1,500-Foot, 2,400-Foot, and 2,800-Foot Sands of the Baton Rouge Area, Louisiana

An updated three-dimensional, groundwater-flow and chloride-transport model (SEAWAT) of the Southern Hills regional aquifer system in southeastern Louisiana and southwestern Mississippi was developed to examine the effects of groundwater withdrawals on the rate and pathways of saltwater migration in the “1,500-foot” sand, “2,400-foot” sand, and “2,800-foot” sand. New interpretations of stratigraphic correlations amongst geophysical well logs were utilized to revise a hydrogeologic-framework that delineates the depth and thickness variations of aquifers and confining units in the Southern Hills regional aquifer system. Regional groundwater flow throughout the Southern Hills regional aquifer system was first simulated with MODFLOW, and [...]
