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 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.

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] |

Retrieved 17 July 2013. This total area constitutes approximately 0.4% of the land mass in the United States. The Delaware River rises in New York's Catskill Mountains flowing southward for 419 miles (674 km) into Delaware Bay where its waters enter the Atlantic Ocean near Cape May in New Jersey and Cape Henlopen in Delaware. There are 216 tributary streams and creeks—an estimated 14,057 miles of streams and creeks—in the watershed. The waters of the Delaware River's basin are used to sustain "fishing, transportation, power, cooling, recreation, and other industrial and residential purposes."
