Charleston is a city in Charleston County, in the U.S. state of South Carolina.The city of Charleston is located just south of the mid-point of South Carolina’s coastline, at the confluence of the Ashley and Cooper Rivers (visible here by the shoreline near the right edge).

According to the United States Census Bureau, the city has a total area of 347.5 square kilometers (134.2 sq mi). 251.2 km2 (97.0 sq mi) of it is land and 44.3 km2 (17.1 sq mi) (15%) of it is water. The old city is located on a peninsula at the point where, as Charlestonians say, “The Ashley and the Cooper Rivers come together to form the Atlantic Ocean.”

The entire peninsula is very low, some of it is landfill material, and as such, it frequently floods during heavy rains, storm surges and unusually high tides. The tidal rivers (Wando, Cooper, Stono, and Ashley) are evidence of a submergent or drowned coastline. In other words, the original rivers had a lower base line, but as the ocean rose or the land sank, the landform was changed. There is a submerged river delta off the mouth of the harbor, and the rivers are deep, affording a good location for a port.

Bodies of Water Along the East Coast of the USA, from New Jersey to South Carolina

Sediments spill from several rivers along the east coast of the United States, from southern New Jersey (top) down to South Carolina (bottom). These are particularly concentrated around the Charleston Harbor in South Carolina (bottom edge), fed by the Ashley and Cooper Rivers, by the mouths of the Cape Fear and the New Rivers in North Carolina,  and in Pamlico Sound, North Carolina (center).

Just north of the greenish Pamlico Sound is Albemarle Sound, lined with dark brown sediments. The sound is actually a large estuary on the coast of North Carolina located at the confluence of a group of rivers, including the Chowan and the Roanoke.

To the north of the Albermarle Sound, the Chesapeake Bay appears relatively free of sediments. The Potomac River flows into this bay on the shores of the state of Maryland.

Finally, continuing northward, the shores of the Delaware Bay, a major estuary outlet of the Delaware River separating the states of Delaware and New Jersey, are lined with brown sediments.
