Potential Changes in Ground-Water Flow and their Effects on the Ecology and Water Resources of the Cape Cod National Seashore, Massachusetts
By John P. Masterson and John W. Portnoy
General Information Product 13
(1) Increased loading of the nutrients nitrogen and phosphorus, and the consequent eutrophication of fresh and coastal surface-water bodies.
(2) Declines in pond levels, increases in the depth to the water table beneath inland wetlands, reductions in streamflow, reductions in ground-water discharge to the coast, and increased saltwater intrusion from increased ground-water withdrawals
(3) Increased erosion rates, damage from higher storm-surge flooding, landward intrusion of seawater in coastal marshes and wetlands, and a decrease in the thickness of the freshwater lens from rising sea levels. Therefore, understanding how ground-water flow affects freshwater and estuarine ecosystems of the Cape Cod National Seashore is vital to managing and protecting these natural resources.
