ABSTRACT
The cross-section model was designed to simulate flow and transport in a vertical plane through the center of the wellfield. Despite the recommendation to be conservative in the initial wellfield design, a total of eight production wells were constructed on a small site known as the Braum Tract. The Dare County wellfield is located on the Outer Banks of North Carolina at the town of Kill Devil Hills. The detailed potentiometric surface and water quality data collected during the initial aquifer performance testing and during wellfield monitoring allowed the model to be calibrated. Using the actual wellfield performance data and the previously collected hydrogeologic data, a three-dimensional groundwater flow and solute-transport model was constructed to assess the future of the wellfield. Initial conditions used in the groundwater model included the initial aquifer parameters and water quality for each layer, as well as the initial potentiometric surface.
