Mississippi River
The Mississippi River is the second-longest river and chief river of the second-largest drainage system in North America, second only to the Hudson Bay drainage system. From its traditional source of Lake Itasca in northern Minnesota, it flows generally south for 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 , of which only about one percent is in Canada. The Mississippi ranks as the thirteenth-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. Native Americans have lived along the Mississippi River and its tributaries for thousands of years. Most were hunter-gathere ...

Flow Measurement
Flow measurement is the quantification of bulk fluid movement. Flow can be measured in a variety of ways. The common types of flowmeters with industrial applications are listed below: * a) Obstruction type (differential pressure or variable area) * b) Inferential (turbine type) * c) Electromagnetic * d) Positive-displacement flowmeters, which accumulate a fixed volume of fluid and then count the number of times the volume is filled to measure flow. * e) Fluid dynamic (vortex shedding) * f) Anemometer * g) Ultrasonic * h) Mass flowmeter ( Coriolis force). Flow measurement methods other than positive-displacement flowmeters rely on forces produced by the flowing stream as it overcomes a known constriction, to indirectly calculate flow. Flow may be measured by measuring the velocity of fluid over a known area. For very large flows, tracer methods may be used to deduce the flow rate from the change in concentration of a dye or radioisotope. Kinds and units of measurement Both gas ...

Dams In Minnesota
A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect or store water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions. The earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC. The word ''dam'' can be traced back to Middle English, and before that, from Middle Dutch, as seen in the names of many old cities, such as Amsterdam and Rotterdam. History Ancient dams Early dam building took place in Mesopotamia and the Middle East. Dams were us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sartell Dam
The Sartell Dam is a dam across the Mississippi River in Sartell, Minnesota in the United States. The dam was used to generate hydroelectric power for the adjoining Sartell Paper Mill before it burned down in 2012. The dam is referred to as the Champion Dam in official documentation. Construction of the structure was begun by the Watab Pulp and Paper Company in 1907 and finished in 1911. Seven workers died during construction, most from drowning as a result of washouts on the site's cofferdam. A cave-in on the dam's west end also killed the son of the project's foreman. The dam was constructed of wooden planks, local granite, and field stones as well as 25,000 barrels concrete. Between 1960 and 1964, the dam was rebuilt by the St. Regis Corporation which had purchased the adjoining paper mill A paper mill is a factory devoted to making paper from vegetable fibres such as wood pulp, old rags, and other ingredients. Prior to the invention and adoption of the Fourdrinier ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Little Falls Dam
Little Falls Dam is a hydroelectric dam across the Mississippi River in the city of Little Falls, Minnesota, United States. History The Little Falls Mill and Land Company was formed in 1849 to build a dam and a sawmill to supply lumber for buildings at Fort Ripley; but when settlers showed up in the area there were other markets for the lumber. James Green, along with a group of co-partners, was the owner of the first dam, a wing dam built on the east channel of the falls. Green died in 1850 and the dam, mill and land were sold. William Sturgis bought the dam and, with Calvin Tuttle and James Fergus, formed the Little Falls Company, later called Little Falls Manufacturing Company. The company built a larger dam, sawmill, cabinet shop and bridge and owned about of land. The new dam replaced the original wing dam, but was built on sand and portions of it were washed out by flood waters in the summer of 1859. The dam was repaired, but washed out again the following summer. The L ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Staurolite
Staurolite is a reddish brown to black, mostly opaque, nesosilicate mineral with a white streak. It crystallizes in the monoclinic crystal system, has a Mohs hardness of 7 to 7.5 and the chemical formula: Fe2+2Al9O6(SiO4)4(O,OH)2. Magnesium, zinc and manganese substitute in the iron site and trivalent iron can substitute for aluminium. Properties Staurolite often occurs twinned in a characteristic cross-shape, called cruciform penetration twinning. In handsamples, macroscopically visible staurolite crystals are of prismatic shape. The mineral often forms porphyroblasts. In thin sections staurolite is commonly twinned and shows lower first order birefringence similar to quartz, with the twinning displaying optical continuity. It can be identified in metamorphic rocks by its swiss cheese appearance (with poikilitic quartz) and often mantled porphyroblastic character. Name The name is derived from the Greek, ''stauros'' for cross and ''lithos'' for stone in reference ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Morrison County, Minnesota
Morrison County is a county in the U.S. state of Minnesota. As of the 2020 census, the population was 34,010. Its county seat is Little Falls. Camp Ripley Military Reservation occupies a significant area in north-central Morrison County. History Dakotah and Ojibwe Indians lived in central Minnesota around the Mississippi River. French and English fur traders and voyageurs traveled through Minnesota from the 17th century to the 19th century. They used the river to transport their goods and trade with the natives. The county was named for fur trading brothers William and Allan Morrison. In the 19th century three prominent explorers led expeditions along the river through the area that became Morrison County. Zebulon Pike came through in 1805. Michigan Territory Governor Lewis Cass led an expedition through the area in 1820. Explorer and scientist Joseph Nicollet created the first accurate map of the area along the river in 1836. Missionaries were some of the area's first Eu ...

Hydroelectric
Hydroelectricity, or hydroelectric power, is electricity generated from hydropower (water power). Hydropower supplies one sixth of the world's electricity, almost 4500 TWh in 2020, which is more than all other renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand. Once a hydroelectric complex is constructed, it produces no direct waste, and almost always emits considerably less greenhouse gas than fossil fuel-powered energy plants.
