Tracing Groundwater Flow on a Barrier Island in the North-east Gulf of Mexico
Groundwater flow on St. George Island, a barrier island in the north-east Gulf of Mexico, was monitored downfield from wastewater systems using artificial tracer techniques. Sulphur hexafluoride and fluorescein dye were used to determine groundwater flow velocity, hydraulic conductivity, and dispersivity at selected sites on the island. Monthly hydraulic head measurements illustrate the aquifer...
متن کاملDelineating the Drivers of Groundwater Flow at a Back Barrier Island – Marsh Transect in Coastal Georgia
Groundwater plays an important role in coastal regions by delivering freshwater and nutrients to near shore and salt marsh environments. To quantify groundwater flow, salinity, temperature and pressure, sensors were installed in shallow piezometers along a transect behind Blackbeard Island, GA. Located approximately 90 m from the nearest tidal creek, the transect reaches from a back barrier isl...
متن کاملGroundwater Thresholds for Root Decomposition and the Relation to Barrier Island Ecological State Changes
GROUNDWATER THRESHOLDS FOR ROOT DECOMPOSITION, AND THE RELATION TO BARRIER ISLAND ECOLOGICAL STATE CHANGES Matthew L. Smith Old Dominion University, 2015 Director: Dr. Frank P. Day Barrier islands off the eastern shore of Virginia exhibit distinct habitats that abruptly transition between periodically brackish/freshwater marshes, wooded swales, and sparsely vegetated dunes. There is strong evid...
متن کاملStability domains in barrier island dune systems
Early ecological descriptions of barrier island dune landscapes recognized the importance of biogeomorphic feedbacks and thresholds. However, these dynamics have not been formally linked to complexity theory. In this article, I develop models of dune landscape phase states, or stability domains, based on a synthesis of these prior studies and statistical analyses. Data for these analyses were o...
متن کاملFeasibility of groundwater withdrawal in a coral island
Groundwater on a small coral island occurs in the form of a lens floating on saline water. The freshwater lens is highly sensitive to various stresses such as pumping, sea tide, etc. Since groundwater is the only source of freshwater on the island, it is not only being utilized for various purposes but also there is growing demand for increased pumpage. In order to assess the impact of addition...
