The Dougherty Plain physiographic province of southwest Georgia is a characterized by karstic topography with deeply incised streams, deep sandy soils with interbedded clay lenses and approximately 11,600 isolated wetlands. The goal of this project was to propose and locally conceptual models of episodic surface flows in the Dougherty Plain. The first specific objective was to determine if episodic flows change when passing through wetlands. Secondly, we monitored water quality of wetlands connected to episodic surface flows and those isolated from such events. Third objective was to determine if wetland hydropattern differed between wetlands connected to episodic flow events and isolated wetlands. Our first study found that isolated wetlands alter episodic surface flow water quality. Secondly, episodic surface flows alter the water quality of isolated wetlands after the cessation of flow. The third study found hydropattern differences in wetlands connected to episodic surface flow and those isolated from such events.
