It is generally flat and low, with large expanses near the tidal shorelines composed of tidal marsh and swamp. Much of the area is covered with pocosin and the higher areas are used for agricultural farmlands. Geographically, in North Carolina and Virginia the Tidewater area is the land between the Suffolk Scarp and the Atlantic Ocean.
Flowing for approximately 50 miles (80 km) before ending in the Albemarle Sound on North Carolina's coast, the river drains about 4,800 square miles (12,000 km 2) of land in North Carolina and Virginia. Flowing through mostly swamp land with occasional high ground, the Chowan River grows to nearly two miles wide (3 km) at its opening to the ...
The dates of spring tides and neap tides, approximately seven days apart, can be determined by the heights of the tides on the classic tide tables: a small range indicates neaps and large indicates springs. This cycle of tides is linked to the phases of the moon, with the highest tides (spring tides) occurring near full moon and new moon.
The Elizabeth River is a 6-mile-long (10 km) [1] tidal estuary forming an arm of Hampton Roads harbor at the southern end of Chesapeake Bay in southeast Virginia in the United States.

At its mouth near Newport News Point, the Elizabeth River and the Nansemond River join the James River to form the harbor area known as Hampton Roads. Between the tip of the Virginia Peninsula near Old Point Comfort and the Willoughby Spit area of Norfolk in South Hampton Roads , a channel leads from Hampton Roads into the southern portion of ...
Salt tide is a phenomenon in which the lower course of a river, with its low altitude with respect to the sea level, becomes salty when the discharge of the river is low during dry season, usually worsened by the result of astronomical high tide.
(This is caused by the time interval associated with the solar tides.) Hundreds of factors are involved in the lunitidal interval, especially near the shoreline. However, for those far away enough from the coast, the dominating consideration is the speed of gravity waves, which increases with the water's depth. It is proportional to the square ...
