Potential Changes in Ground-Water Flow and their Effects on the Ecology and Water Resources of the Cape Cod National Seashore, MassachusettsBy John P. Masterson and John W. PortnoyGeneral 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.
