C And D Canal
The Chesapeake & Delaware Canal (C&D Canal) is a -long, -wide and -deep ship canal that connects the Delaware River with the Chesapeake Bay in the states of Delaware and Maryland in the United States. In the mid‑17th century, mapmaker Augustine Herman observed that these great bodies of water were separated only by a narrow strip of land. In 1764, a survey of possible water routes across the Delmarva Peninsula was made, but little action followed. The idea was raised again in 1788 by regional business leaders, including noted Philadelphians Benjamin Franklin and Benjamin Rush. Despite the beginnings of a commercial venture in 1802—coincident with Canal Mania in England and Wales—it wasn't until 1829 before the C&D Canal Company could, at last, announce the waterway "open for business". Its construction cost of $3.5 million (equivalent to $ million in ) made it one of the most expensive canal projects of its time. In the present era, the C&D Canal is owned and operat ...

Chesapeake City, Maryland
Chesapeake City is a town in Cecil County, Maryland, United States. The population was 736 at the 2020 census. The town was originally named by Bohemian colonist Augustine Herman the Village of Bohemia — or Bohemia Manor — but the name was changed in 1839 after the Chesapeake and Delaware Canal (C&D Canal) was built in 1829. Today, the town contains numerous old homes from that era that have been converted into bed and breakfasts, restaurants and the local historical museum. History The town was separated into north and south sections when the C&D Canal was built through the middle of the town. The two were connected by a drawbridge until 1942 when that was destroyed by a freighter that struck it. The current bridge opened in 1949. The new bridge had to be tall enough to allow supertankers to pass beneath it, resulting in a structure so high and long that cars no longer went into the city to cross the canal. Business declined for decades thereafter. Chesapeake City is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
