White Clay Creek
White Clay Creek is an U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map accessed April 1, 2011 tributary of the Christina River in southern Pennsylvania and northern Delaware in the United States. It is renowned for its scenic character and is largely federally protected. The White Clay Creek watershed is home to nearly 100,000 people and includes parts of Chester County, Pennsylvania and New Castle County, Delaware. The Pennsylvania portion still retains a rural character while the Delaware portion is more suburbanized. Sediment eroded from the rolling hills of Chester County is carried into the White Clay, probably accounting for the creek's name. The majority of the stream is in the Piedmont region which is characterized by rolling hills, plateaus, and stream valleys. The southern portion of the stream, near Newark is in the Atlantic Coastal Plain, a relatively flat area that is dotted with large tidal wetlands. The White Cla ...

Christina River
The Christina River is a tributary of the Delaware River, approximately 35 miles (56 km) long, in northern Delaware in the United States, also flowing through small areas of southeastern Pennsylvania and northeastern Maryland. Near its mouth the river flows past downtown Wilmington, Delaware, forming the city's harbor for traffic on the Delaware River. The Port of Wilmington, opened in 1923 at the river's mouth, handles international cargo and trade. The river rises in southeastern Pennsylvania, in Franklin Township in southern Chester County, and initially flows southeastwardly, passing through the northeastern extremity of Maryland in northeastern Cecil County, into New Castle County in Delaware, where it flows through western and southern areas of the city of Newark and then turns northeastwardly, passing the town of Newport and approaching Wilmington from the southwest. It receives White Clay Creek from the west near Newport, and Brandywine Creek in Wilmingt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Delaware River
The Delaware River is a major river in the Mid-Atlantic (United States), Mid-Atlantic region of the United States. From the meeting of its branches in Hancock (village), New York, Hancock, New York, the river flows for along the borders of New York (state), New York, Pennsylvania, New Jersey, and Delaware, before emptying into Delaware Bay. It is the longest free-flowing river in the Eastern United States. The river has been recognized by the National Wildlife Federation as one of the country's Great Waters. The river's drainage basin, watershed drains an area of and provides drinking water for 17 million people. The river has two branches that rise in the Catskill Mountains of New York: the West Branch Delaware River, West Branch at Mount Jefferson (New York), Mount Jefferson in Jefferson, New York, Jefferson, Schoharie County, New York, Schoharie County, and the East Branch Delaware River, East Branch at Grand Gorge, New York, Grand Gorge, Delaware County, New York, ...

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 ...

Atlantic Ocean
The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about . It covers approximately 20% of Earth's surface and about 29% of its water surface area. It is known to separate the " Old World" of Africa, Europe and Asia from the "New World" of the Americas in the European perception of the World. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and North and South America to the west. As one component of the interconnected World Ocean, it is connected in the north to the Arctic Ocean, to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south (other definitions describe the Atlantic as extending southward to Antarctica). The Atlantic Ocean is divided in two parts, by the Equatorial Counter Current, with the North(ern) Atlantic Ocean and the South(ern) Atlantic Ocean split at about 8°N.

New Castle County, Delaware
New Castle County is the northernmost of the three counties of the U.S. state of Delaware (New Castle, Kent, and Sussex). As of the 2020 census, the population was 570,719, making it the most populous county in Delaware, with nearly 60% of the state's population of 989,948. The county seat is Wilmington, which is also the state's most populous city. New Castle County is included in the Philadelphia- Camden- Wilmington, PA-NJ-DE-MD Metropolitan Statistical Area. The county is named after William Cavendish, 1st Duke of Newcastle (–1676). New Castle County has the highest population and population density of any Delaware county, and it is the smallest county in the state by area. It has more people than the other two counties, Kent and Sussex, combined. It is also the most economically developed of the three. History The first permanent European settlement on Delaware soil was Fort Christina, resulting from Peter Minuit's 1638 expedition on the Swedish vessels ''Fogel Grip' ...

Geographic Names Information System
The Geographic Names Information System (GNIS) is a database of name and locative information about more than two million physical and cultural features throughout the United States and its territories, Antarctica, and the associated states of the Marshall Islands, Federated States of Micronesia, and Palau. It is a type of gazetteer. It was developed by the United States Geological Survey (USGS) in cooperation with the United States Board on Geographic Names (BGN) to promote the standardization of feature names. Data were collected in two phases. Although a third phase was considered, which would have handled name changes where local usages differed from maps, it was never begun. The database is part of a system that includes topographic map names and bibliographic references. The names of books and historic maps that confirm the feature or place name are cited. Variant names, alternatives to official federal names for a feature, are also recorded. Each feature receives a per ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Topographic Wetness Index
The topographic wetness index (TWI), also known as the compound topographic index (CTI), is a steady state wetness index. It is commonly used to quantify topographic control on hydrological processes. The index is a function of both the slope and the upstream contributing area per unit width orthogonal to the flow direction. The index was designed for hillslope catenas. Accumulation numbers in flat areas will be very large, so TWI will not be a relevant variable. The index is highly correlated with several soil attributes such as horizon depth, silt percentage, organic matter content, and phosphorus. Methods of computing this index differ primarily in the way the upslope contributing area is calculated. Definition The topographic wetness index is defined as: \ln where a is the local upslope area draining through a certain point per unit contour length and \tan b is the local slope in radians. The TWI has been used to study spatial scale effects on hydrological processes. The t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rivers Of New Castle County, Delaware
A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases, a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as creek, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague. Rivers are part of the water cycle. Water generally collects in a river from precipitation through a drainage basin from surface runoff and other sources such as groundwater recharge, springs, a ...

Tributaries Of The Christina River
A tributary, or affluent, is a stream or river that flows into a larger stream or main stem (or parent) river or a lake. A tributary does not flow directly into a sea or ocean. Tributaries and the main stem river drain the surrounding drainage basin of its surface water and groundwater, leading the water out into an ocean. The Irtysh is a chief tributary of the Ob river and is also the longest tributary river in the world with a length of . The Madeira River is the largest tributary river by volume in the world with an average discharge of . A confluence, where two or more bodies of water meet, usually refers to the joining of tributaries. The opposite to a tributary is a distributary, a river or stream that branches off from and flows away from the main stream. PhysicalGeography.net, Michael Pidwirny & Scott ...
