Water-Level Analysis for Cumberland Sound, Georgia.
Cumberland Sound, Georgia, is a large and complex estuary covering an area of approximately 240 square miles, which is connected to the Atlantic Ocean through a dredged inlet channel called St Marys Entrance. St. Marys Entrance consists of a Federally maintained navigation channel protected by two j...
