Tennessee water resource region

Last updated

The Tennessee water resource region is one of 21 major geographic areas, or regions, in the first level of classification used by the United States Geological Survey to divide and sub-divide the United States into successively smaller hydrologic units. These geographic areas contain either the drainage area of a major river, or the combined drainage areas of a series of rivers. [1] [2]

Water resource region

A water resource region is the first level of classification used by the United States Geological Survey to divide and sub-divide the United States into successively smaller hydrologic units.

United States Geological Survey Scientific agency of the United States government

The United States Geological Survey is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The organization has four major science disciplines, concerning biology, geography, geology, and hydrology. The USGS is a fact-finding research organization with no regulatory responsibility.

The Tennessee region, which is listed with a 2-digit hydrologic unit code (HUC) of 06, has an approximate size of 40,908 square mile s (105,950 square kilometers ), and consists of 4 subregions, which are listed with the 4-digit HUCs 0601 through 0604.

The square mile is an imperial and US unit of measure for an area equal to the area of a square with a side length of one statute mile. It should not be confused with miles square, which refers to a square region with each side having the specified length. For instance, 20 miles square has an area equal to 400 square miles; a rectangle of 10 × 40 miles likewise has an area of 400 square miles, but it is not 20 miles square.

Square kilometre or square kilometer, symbol km2, is a multiple of the square metre, the SI unit of area or surface area.

This region includes the drainage of the Tennessee River Basin. Includes parts of Alabama, Georgia, Kentucky, Mississippi, North Carolina, Tennessee, and Virginia. [3]

Tennessee River River in the United States

The Tennessee River is the largest tributary of the Ohio River. It is approximately 652 miles (1,049 km) long and is located in the southeastern United States in the Tennessee Valley. The river was once popularly known as the Cherokee River, among other names, as many of the Cherokee had their territory along its banks, especially in eastern Tennessee and northern Alabama. Its current name is derived from the Cherokee village Tanasi.

Alabama A state in the United States

Alabama is a state in the southeastern region of the United States. It is bordered by Tennessee to the north, Georgia to the east, Florida and the Gulf of Mexico to the south, and Mississippi to the west. Alabama is the 30th largest by area and the 24th-most populous of the U.S. states. With a total of 1,500 miles (2,400 km) of inland waterways, Alabama has among the most of any state.

Georgia (U.S. state) U.S. state in the United States

Georgia is a state located in the southeastern region of the United States. Georgia is the 24th largest in area and 8th-most populous of the 50 United States. Georgia is bordered to the north by Tennessee and North Carolina, to the northeast by South Carolina, to the southeast by the Atlantic Ocean, to the south by Florida, and to the west by Alabama. Atlanta, a "beta(+)" global city, is both the state's capital and largest city. The Atlanta metropolitan area, with an estimated population of 5,949,951 in 2018, is the 9th most populous metropolitan area in the United States and contains about 60% of the entire state population.
