Lock And Dam No. 1
Ford Dam, officially known as Lock and Dam No. 1, is on the Upper Mississippi River and is located between Minneapolis and Saint Paul, Minnesota just north of the confluence of the Mississippi with the Minnesota River at Mississippi River mile 847.9, in Minneapolis. The powerhouse portion was previously owned by the Ford Motor Company, which operated a hydroelectric power station to feed electricity to its Twin Cities Assembly Plant on the east side of the river. It was sold to Brookfield Power Co. in April 2008. The dual- lock facility and dam was built and is operated by the St. Paul district of the U.S. Army Corps of Engineers' Mississippi Valley Division. Facility The first facility at the site went into operation in 1917 and superseded the role of the earlier Lock and Dam No. 2 (today known as the Meeker Island Lock and Dam). The facility was rebuilt in 1929, and an expansion from one lock to two locks was completed in 1932. Each lock is wide by long (17 × 122 meters), ...

Upper Mississippi River
The Upper Mississippi River is the portion of the Mississippi River upstream of St. Louis, Missouri, United States, at the confluence of its main tributary, the Missouri River. History In terms of geologic and hydrographic history, the Upper Mississippi east and south of Fort Snelling is a portion of the now-extinct Glacial River Warren which carved the valley of the Minnesota River, permitting the immense Glacial Lake Agassiz to join the world's oceans at the Gulf of Mexico. The collapse of ice dams holding back Glacial Lake Duluth and Glacial Lake Grantsburg carved out the Dalles of the St. Croix River at Interstate Park. The Upper Mississippi River valley likely originated as an ice-marginal stream during the Pre-Illinoian Stage. The Driftless Area is a portion of North America left unglaciated at that ice age's height, hence not smoothed out or covered over by previous geological processes. Inasmuch as the Wisconsin glaciation formed lobes that met (and blocked) wher ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydraulic
Hydraulics (from Greek: Υδραυλική) is a technology and applied science using engineering, chemistry, and other sciences involving the mechanical properties and use of liquids. At a very basic level, hydraulics is the liquid counterpart of pneumatics, which concerns gases. Fluid mechanics provides the theoretical foundation for hydraulics, which focuses on the applied engineering using the properties of fluids. In its fluid power applications, hydraulics is used for the generation, control, and transmission of power by the use of pressurized liquids. Hydraulic topics range through some parts of science and most of engineering modules, and cover concepts such as pipe flow, dam design, fluidics and fluid control circuitry. The principles of hydraulics are in use naturally in the human body within the vascular system and erectile tissue. Free surface hydraulics is the branch of hydraulics dealing with free surface flow, such as occurring in rivers, canals, lakes, estuar ...

Twin Cities Assembly Plant
The Twin Cities Assembly Plant is a former Ford Motor Company manufacturing facility in Saint Paul, Minnesota, United States, that operated from 1925 to 2011. In 1912, Ford's first assembly and sales activities in Minnesota began in a former warehouse in Minneapolis. By 1925, Ford had relocated its local operations to the bluffs above the Mississippi River in the Highland Park neighborhood of Saint Paul. In 2006, Ford officials announced plans to close the factory, though it operated for three years past the 2008 closure date initially announced. At the time of its closure, it was the oldest Ford plant in continuous operation. The plant's final truck was completed on December 16, 2011. All of the facility's buildings were demolished and the site underwent extensive environmental remediation in the late 2010s, paid for by the Ford company. Following a multi-year planning and community engagement process, the site was sold to the Ryan Companies, who began redevelopment of the site ...

Intercity Bridge
The Intercity Bridge, more commonly known as the Ford Parkway Bridge (and sometimes referred to as the 46th Street Bridge by residents of Minneapolis), is a reinforced concrete arch bridge that spans the Mississippi River between Minneapolis, Minnesota and St. Paul, Minnesota, United States. It connects 46th Street in Minneapolis with Ford Parkway in Saint Paul. The bridge is historically significant as one of the largest reinforced concrete bridges ever built in Minnesota. It was built in 1925-1927 by James O. Heyworth, Inc. and was designed by Martin Sigvart Grytbak. The Intercity Bridge was listed on the National Register of Historic Places in 1989. It is notable as one of the monumental concrete rib-arch bridges spanning the high river bluffs along the Mississippi River, along with the Franklin Avenue Bridge, the Third Avenue Bridge, the 10th Avenue Bridge, and the Robert Street Bridge. The bridge was originally built to service Ford's Twin Cities Assembly Plant, so Mi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coon Rapids, Minnesota
Coon Rapids is a northern suburb of Minneapolis, and is the largest city in Anoka County, Minnesota, United States. The population was 63,599 at the 2020 census, making it the fifteenth largest city in Minnesota and the seventh largest Twin Cities suburb.

Head Of Navigation
The head of navigation is the farthest point above the mouth of a river that can be navigated by ships. Determining the head of navigation can be subjective on many streams, as the point may vary greatly with the size or the draft of the ship being contemplated for navigation and the seasonal water level. On others, it is quite objective, being caused by a waterfall, a low bridge that is not a drawbridge, or a dam without navigation locks. Several rivers in a region may have their heads of navigation along a line called the fall line. Longer rivers such as the River Thames may have several heads of navigation depending on boat size. In the case of the Thames, that includes London Bridge, which historically served as the head of navigation for tall ships; Osney Bridge in Oxford, which has the lowest headroom of any bridge on the Thames that generally restricts navigation to smaller vessels such as narrowboats and cabin cruisers, and the long reach above St John's Lock, the first ...

Minneapolis
Minneapolis () is the largest city in Minnesota, United States, and the county seat of Hennepin County. The city is abundant in water, with thirteen lakes, wetlands, the Mississippi River, creeks and waterfalls. Minneapolis has its origins in timber and as the flour milling capital of the world. It occupies both banks of the Mississippi River and adjoins Saint Paul, the state capital of Minnesota. Prior to European settlement, the site of Minneapolis was inhabited by Dakota people. The settlement was founded along Saint Anthony Falls on a section of land north of Fort Snelling; its growth is attributed to its proximity to the fort and the falls providing power for industrial activity. , the city has an estimated 425,336 inhabitants. It is the most populous city in the state and the 46th-most-populous city in the United States. Minneapolis, Saint Paul and the surrounding area are collectively known as the Twin Cities. Minneapolis has one of the most extensive public par ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saint Anthony Falls
Saint Anthony Falls, or the Falls of Saint Anthony ( dak, italics=no, Owámniyomni, ) located at the northeastern edge of downtown Minneapolis, Minnesota, is the only natural major waterfall on the Mississippi River. Throughout the mid-to-late 1800’s, various dams were built atop the east and west faces of the falls to support the milling industry that spurred the growth of the city of Minneapolis. In 1880, the central face of the falls was reinforced with a sloping timber apron to stop the upstream erosion of the falls. In the 1950s, the apron was rebuilt with concrete, which makes up the most visible portion of the falls today. A series of locks were constructed in the 1950s and 1960s to extend navigation to points upstream. The falls were renamed from their Dakota title in 1680 by Father Louis Hennepin after his patron saint, St. Anthony of Padua. The towns of St. Anthony and Minneapolis, which had developed on the east and west sides of the falls, respectively, merged in ...

Reinforced Concrete
Reinforced concrete (RC), also called reinforced cement concrete (RCC) and ferroconcrete, is a composite material in which concrete's relatively low tensile strength and ductility are compensated for by the inclusion of reinforcement having higher tensile strength or ductility. The reinforcement is usually, though not necessarily, steel bars ( rebar) and is usually embedded passively in the concrete before the concrete sets. However, post-tensioning is also employed as a technique to reinforce the concrete. In terms of volume used annually, it is one of the most common engineering materials. In corrosion engineering terms, when designed correctly, the alkalinity of the concrete protects the steel rebar from corrosion. Description Reinforcing schemes are generally designed to resist tensile stresses in particular regions of the concrete that might cause unacceptable cracking and/or structural failure. Modern reinforced concrete can contain varied reinforcing materials made of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
