Watch a conference presentation from the Georgia Water Resources Conference exploring a 2D water table model that leverages GIS and topographical data to understand groundwater dynamics. Learn about an innovative approach to modeling water table positions using Dupuit's equations for one-dimensional horizontal flow in phreatic aquifers between parallel rivers. Discover how this model helps analyze nitrate transport in fertilized pine plantations across three headwater streams in the Upper Atlantic Coastal Plain. Examine findings about a nitrate pulse detected after clearcut and fertilization, its persistence in the surficial aquifer, and its limited transport to riparian groundwater and streamwater over 7 years. Understand how the model estimates catchment-wide transit times and subsurface water storage to evaluate questions about nitrate transport patterns from plantation sites.
