Atlantic Seaboard Watershed
The Atlantic seaboard watershed is a watershed of the Atlantic Ocean in eastern North America along the Atlantic Canada (Maritimes) coast south of the Gulf of Saint Lawrence Watershed, and the East Coast of the United States north of the Kissimmee River watershed of Lake Okeechobee basin in the central Florida Peninsula. The continental area east of the Appalachian Mountains and highlands to the north and south is demarcated on the south by drainage to the Lake Okeechobee basin (which drains both westward to the Gulf and eastward to ocean), the Eastern Continental Divide (ECD) to the west, and the Saint Lawrence divide to the north. US physiographic regions of this watershed are the Atlantic Plain and the Appalachian Mountains & Highlands. ;Sub-watersheds adjacent to the Saint Lawrence divide: *Chedabucto Bay: *Gulf of Maine: *Long Island Sound: *Lower New York Bay: > ;Other notable sub-watersheds: *Delaware Bay: — larger than several, but not adjacent to either divide ...

Drainage Basin
A drainage basin is an area of land where all flowing surface water converges to a single point, such as a river mouth, or flows into another body of water, such as a lake or ocean. A basin is separated from adjacent basins by a perimeter, the '' drainage divide'', made up of a succession of elevated features, such as ridges and hills. A basin may consist of smaller basins that merge at river confluences, forming a hierarchical pattern. Other terms for a drainage basin are catchment area, catchment basin, drainage area, river basin, water basin, and impluvium. In North America, they are commonly called a watershed, though in other English-speaking places, "watershed" is used only in its original sense, that of a drainage divide. In a closed drainage basin, or endorheic basin, the water converges to a single point inside the basin, known as a sink, which may be a permanent lake, a dry lake, or a point where surface water is lost underground. Drainage basins are similar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Appalachian Mountains
The Appalachian Mountains, often called the Appalachians, (french: Appalaches), are a system of mountains in eastern to northeastern North America. The Appalachians first formed roughly 480 million years ago during the Ordovician Period. They once reached elevations similar to those of the Alps and the Rocky Mountains before experiencing natural erosion. The Appalachian chain is a barrier to east–west travel, as it forms a series of alternating ridgelines and valleys oriented in opposition to most highways and railroads running east–west. Definitions vary on the precise boundaries of the Appalachians. The United States Geological Survey (USGS) defines the ''Appalachian Highlands'' physiographic division as consisting of 13 provinces: the Atlantic Coast Uplands, Eastern Newfoundland Atlantic, Maritime Acadian Highlands, Maritime Plain, Notre Dame and Mégantic Mountains, Western Newfoundland Mountains, Piedmont, Blue Ridge, Valley and Ridge, St. Lawrence Valley, Appalac ...

Albemarle Sound
Albemarle Sound () is a large estuary on the coast of North Carolina in the United States located at the confluence of a group of rivers, including the Chowan and Roanoke. It is separated from the Atlantic Ocean by the Currituck Banks, a barrier peninsula upon which the town of Kitty Hawk is located, at the eastern edge of the sound, and part of the greater Outer Banks region. Roanoke Island is situated at the southeastern corner of the sound, where it connects to Pamlico Sound. Much of the water in the Albemarle Sound is brackish or fresh, as opposed to the saltwater of the ocean, as a result of river water pouring into the sound. Some small portions of the Albemarle have been given their own "sound" names to distinguish these bodies of water from other parts of the large estuary. The Croatan Sound, for instance, lies between mainland Dare County and Roanoke Island. The water bordering the eastern shore of the island to the Outer Banks is commonly referred to as Roanoke ...

Chesapeake Bay
The Chesapeake Bay ( ) is the largest estuary in the United States. The Bay is located in the Mid-Atlantic (United States), Mid-Atlantic region and is primarily separated from the Atlantic Ocean by the Delmarva Peninsula (including the parts: the Eastern Shore of Maryland / Eastern Shore of Virginia and the state of Delaware) with its mouth of the Bay at the south end located between Cape Henry and Cape Charles (headland), Cape Charles. With its northern portion in Maryland and the southern part in Virginia, the Chesapeake Bay is a very important feature for the ecology and economy of those two states, as well as others surrounding within its watershed. More than 150 major rivers and streams flow into the Bay's drainage basin, which covers parts of six states (New York, Pennsylvania, Delaware, Maryland, Virginia and West Virginia) and all of District of Columbia. The Bay is approximately long from its northern headwaters in the Susquehanna River to its outlet in the Atlantic Ocea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chincoteague Bay
Chincoteague Bay () is a lagoon between the Atlantic barrier islands of Assateague and Chincoteague and the mainland of Worcester County, Maryland and northern Accomack County, Virginia. At the bay's northern end, where it narrows between Assateague and Sinepuxent Neck, it becomes Sinepuxent Bay; Chincoteague Bay's southern end drains into the Atlantic Ocean via Queen Sound and Chincoteague Inlet. No major river flows into Chincoteague Bay—its largest tributaries are Newport Creek in Worcester County and Swans Gut Creek in Accomack County. During the late 19th and early 20th centuries, Chincoteague Bay was well known for its shellfish industry, which shipped oysters, crabs, and clams to Baltimore, Philadelphia, and New York. The shellfish industry was based in several landings and small towns: Taylors Landing at Girdletree, Maryland, George Island Landing at Stockton, Maryland, and Franklin City and Greenbackville in Virginia. Girdletree, Stockton, and Franklin City were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sinepuxent Bay
Sinepuxent Bay is an inland waterway which connects Chincoteague Bay to Isle of Wight Bay, and is connected to the Atlantic Ocean via the Ocean City Inlet. It separates Sinepuxent Neck, in Worcester County, Maryland from Assateague Island, and West Ocean City, Maryland from downtown Ocean City. Islands in the Sinepuxent Bay include Horn Island and Skimmer Island. It is crossed by the Harry W. Kelley Memorial Bridge on U.S. Route 50 in Maryland, U.S. Route 50 and the Verrazano Bridge (Maryland), Verrazano Bridge on Maryland Route 611 (not to be confused with the Verrazano-Narrows Bridge in New York City; both were named for Giovanni da Verrazzano, who explored the coastline in 1524). The bay is the location of the islands that compose the Sinepuxent Bay Wildlife Management Area. Historically the area was referred to by various names including Sinepuxent, Sene Puxon, Synepuxent, Cinnepuxon, ''et al''.

Isle Of Wight Bay
Isle of Wight Bay is a lagoon that separates part of mainland Worcester County, Maryland from the midtown part of Ocean City, also in Worcester County. To the north, it connects to the Assawoman Bay just south of the Assawoman Bay Bridge, and to the south it connects to the Sinepuxent Bay at the north end of West Ocean City where the bay narrows between the Thoroughfare channel and Mallard Island. The major tributary of Isle of Wight Bay is the St. Martin's River; other tributaries include Turville Creek Turville is a village and civil parish in Buckinghamshire, England. It is in the Chiltern Hills, west of High Wycombe, east-southeast of Watlington, north of Henley-on-Thames and 2 miles (3 km) from the Oxfordshire border.

Assawoman Bay
Assawoman Bay (), once called Assawoman Sound, is a lagoon that is located between Ocean City, Maryland and mainland Delmarva. The bay is located on the northern end of the city, the bay on the southern end is called the Isle of Wight Bay. Another bay called Little Assawoman Bay extends into southern Delaware, and is geologically separated from the main estuaries, by a narrow strait locally referred to as "The Ditch" which crosses the Transpeninsular Line. The larger bay is sometimes called "Big Assawoman Bay", to distinguish it from the smaller bay, though this is often meant to be a tongue-in-cheek The idiom tongue-in-cheek refers to a humorous or sarcastic statement expressed in a serious manner. History The phrase originally expressed contempt, but by 1842 had acquired its modern meaning. Early users of the phrase include Sir Walter Scott ... rendering of the name.

Indian River Bay
Indian River Bay is a body of water in Sussex County, Delaware. It is part of Delaware's inland bay system, along with Little Assawoman Bay and Rehoboth Bay. Fed by the Indian River at its western end, the bay is connected to the Atlantic Ocean to the east via the Indian River Inlet. A natural waterway that shifted up and down a two-mile (3.2 km) stretch of the coast until 1928, the inlet was kept in its current location by dredging between 1928 and 1937, and in 1938 was fixed in place by the construction of jetties. The Charles W. Cullen Bridge, commonly known as the Indian River Inlet Bridge, spans the inlet. Indian River Bay is unique among Delaware's inland bays in that it is a drowned river valley, whereas Delaware's other bays are estuaries built on sand bars.Delaware Inland Bays Compreh ...

Rehoboth Bay
Rehoboth Bay is a body of water in Sussex County, Delaware. It is connected to the Broadkill River by the Lewes and Rehoboth Canal. It is part of Delaware's inland bay system, along with Little Assawoman Bay and Indian River Bay. Of Delaware's Inland Bays, both Rehoboth Bay and Little Assawoman Bay are barbuilt estuaries, while Indian River Bay is a drowned river valley. Rehoboth Bay is the northernmost of Delaware's inland bays. Depth is generally shallow, less than 6 to 7 feet below Mean Lower Low Water. Surface area of the bay is approximately 13 square miles. Rehoboth Bay receives fresh water discharges from a number of small creeks along the bay, including White Oak Creek, Love Creek, Herring Creek, and Guinea Creek. Rehoboth Bay is linked to Indian River Bay to the south, providing tidal exchange with the Atlantic Ocean through Indian River Inlet, which is stabilized by two parallel stone jetties. At the north end of the Bay, the Lewes-Rehoboth Canal connects Rehoboth B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Delaware Bay
Delaware Bay is the estuary outlet of the Delaware River on the northeast seaboard of the United States. It is approximately in area, the bay's freshwater mixes for many miles with the saltwater of the Atlantic Ocean. The bay is bordered inland by the states of Delaware and New Jersey, and the Delaware Capes, Cape Henlopen and Cape May, on the Atlantic. Delaware Bay is bordered by six counties: Sussex, Kent, and New Castle in Delaware, along with Cape May, Cumberland, and Salem in New Jersey. The Cape May–Lewes Ferry crosses Delaware Bay from Cape May, New Jersey, to Lewes, Delaware. The bay's ports are managed by the Delaware River and Bay Authority. The shores of the bay are largely composed of salt marshes and mudflats, with only small communities inhabiting the shore of the lower bay. Several of the rivers hold protected status for their salt marsh wetlands bordering the bay, which serves as a breeding ground for many aquatic species, including horseshoe crabs. The bay ...

Lower New York Bay
Lower New York Bay is a section of New York Bay south of the Narrows (the strait between Staten Island and Brooklyn). The eastern end of the Bay is marked by two spits of land, Sandy Hook, New Jersey, and Rockaway, Queens. The waterway between the spits connects the Bay to the Atlantic Ocean at the New York Bight. Traversing the floor of the Bay southeasterly from the Narrows to the Bight and beyond is Hudson Canyon. Roughly the northeastern portion of the Bay from the Narrows to Sandy Hook is known as the Lower Bay (named in relation to the neighboring Upper ew YorkBay); roughly the western portion of the Bay (including the portion at the mouth of New Jersey's Raritan River) is called Raritan Bay; and roughly the southeastern portion of the Bay (that is, the portion south and the portion southwest from Sandy Hook) is known as Sandy Hook Bay.
