The Mississippi River is the second-longest river and chief river of the second-largest drainage system on the North American continent, second only to the Hudson Bay drainage system. From its traditional source of Lake Itasca in northern Minnesota, it flows generally south for 2,340 miles (3,770 km) to the Mississippi River Delta in the Gulf of Mexico. With its many tributaries, the Mississippi's watershed drains all or parts of 32 U.S. states and two Canadian provinces between the Rocky and Appalachian mountains. The main stem is entirely within the United States; the total drainage basin is 1,151,000 sq mi (2,980,000 km2), of which only about one percent is in Canada. The Mississippi ranks as the fourteenth-largest river by discharge in the world. The river either borders or passes through the states of Minnesota, Wisconsin, Iowa, Illinois, Missouri, Kentucky, Tennessee, Arkansas, Mississippi, and Louisiana.
A levee, dike, dyke, embankment, floodbank, or stop bank is an elongated naturally occurring ridge or artificially constructed fill or wall that regulates water levels. It is usually earthen and often parallel to the course of a river in its floodplain or along low-lying coastlines.
Missouri, a state near the geographical center of the United States, has three distinct physiographic divisions:
In geography and fluvial geomorphology, a thalweg or talweg is the line of lowest elevation within a valley or watercourse.
The Gulf Coastal Plain extends around the Gulf of Mexico in the Southern United States and eastern Mexico.
The Twelve-Mile Circle is an approximately circular arc which forms most of the boundary between the Commonwealth of Pennsylvania and the State of Delaware in the United States. It is not actually a circle, but rather a combination of different circular arcs that have been feathered together.
The Honey War was a bloodless territorial dispute in 1839 between Iowa Territory and Missouri over their border.
The Treaty of Beaufort, also called the Beaufort Convention, is the treaty that originally set the all-river boundary between the U.S. states of Georgia and South Carolina. It was named for Beaufort, South Carolina, where it was signed in 1787.
A meander is one of a series of regular sinuous curves in the channel of a river or other watercourse. It is produced as a watercourse erodes the sediments of an outer, concave bank and deposits sediments on an inner, convex bank which is typically a point bar. The result of this coupled erosion and sedimentation is the formation of a sinuous course as the channel migrates back and forth across the axis of a floodplain.
In real property law, avulsion refers to a sudden loss of land, which results from the action of water. It differs from accretion, which describes a gradual addition to land resulting from the action of water.
Sir Creek, originally Ban Ganga, is a 96-km (60-mi) tidal estuary in the uninhabited marshlands of the Indus River Delta on the border between India and Pakistan. The creek flows into the Arabian Sea and separates Gujarat state in India from Sindh province in Pakistan. The long-standing India-Pakistan Sir Creek border dispute stems from the demarcation "from the mouth of Sir Creek to the top of Sir Creek, and from the top of Sir Creek eastward to a point on the line designated on the Western Terminus". From this point onward, the boundary is unambiguously fixed as defined by the Tribunal Award of 1968.
River bifurcation occurs when a river flowing in a single stream separates into two or more separate streams which then continue downstream. Some rivers form complex networks of distributaries, typically in their deltas. If the streams eventually merge again or empty into the same body of water, then the bifurcation forms a river island.
The United States of America was created on July 4, 1776, with the Declaration of Independence of thirteen British colonies in North America. In the Lee Resolution of July 2, 1776, the colonies resolved that they were free and independent states. The union was formalized in the Articles of Confederation, which came into force on March 1, 1781, after being ratified by all 13 states. Their independence was recognized by Great Britain in the Treaty of Paris of 1783, which concluded the American Revolutionary War. This effectively doubled the size of the colonies, now able to stretch west past the Proclamation Line to the Mississippi River. This land was organized into territories and then states, though there remained some conflict with the sea-to-sea grants claimed by some of the original colonies. In time, these grants were ceded to the federal government.
Reverie is an unincorporated community in Tipton County, Tennessee, United States. In 2001, the population was 11.
New Moore, also known as South Talpatti and Purbasha Island, was a small uninhabited offshore sandbar island in the Bay of Bengal, off the coast of the Ganges-Brahmaputra delta region. It emerged in the Bay of Bengal in the aftermath of the Bhola cyclone in November 1970, and disappeared around March 2010.
New Mexico v. Texas, 275 U.S. 279 (1927), was a United States Supreme Court case that determined the boundary between Texas and New Mexico in the vicinity of El Paso, Texas.
A stream is a body of water with surface water flowing within the bed and banks of a channel. The flow of a stream is controlled by three inputs – surface water, subsurface water and groundwater. The surface and subsurface water are highly variable between periods of rainfall. Groundwater, on the other hand, has a relatively constant input and is controlled more by long-term patterns of precipitation. The stream encompasses surface, subsurface and groundwater fluxes that respond to geological, geomorphological, hydrological and biotic controls.
In sedimentary geology and fluvial geomorphology, avulsion is the rapid abandonment of a river channel and the formation of a new river channel. Avulsions occur as a result of channel slopes that are much less steep than the slope that the river could travel if it took a new course.
Corona is an unincorporated community in Tipton County, Tennessee, United States.
