Black Run (Spruce Run Tributary)
Black Run (also known as Black's Run) is a tributary of Spruce Run in Union County, Pennsylvania, in the United States. It is approximately long and flows through West Buffalo Township and Buffalo Township. The watershed of the stream has an area of . The stream has two unnamed tributaries and is not designated as an impaired waterbody. Its watershed is mostly forested, but there is some agricultural land. A few bridges have been constructed across the stream. Course Black Run begins on Buffalo Mountain in West Buffalo Township. It flows southeast for several tenths of a mile, reaching the base of the mountain and entering a valley. Here, it turns east for a few miles, entering Buffalo Township and receiving two unnamed tributaries from the left. The stream eventually turns south-southeast for more than a mile before reaching its confluence with Spruce Run. Black Run joins Spruce Run upstream of its mouth.

River Source
The headwaters of a river or stream is the farthest place in that river or stream from its estuary or downstream confluence with another river, as measured along the course of the river. It is also known as a river's source. Definition The United States Geological Survey (USGS) states that a river's "length may be considered to be the distance from the mouth to the most distant headwater source (irrespective of stream name), or from the mouth to the headwaters of the stream commonly known as the source stream". As an example of the second definition above, the USGS at times considers the Missouri River as a tributary of the Mississippi River. But it also follows the first definition above (along with virtually all other geographic authorities and publications) in using the combined Missouri—lower Mississippi length figure in lists of lengths of rivers around the world. Most rivers have numerous tributaries and change names often; it is customary to regard the longest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rivers Of Union County, Pennsylvania
A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases, a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as creek, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague. Rivers are part of the water cycle. Water generally collects in a river from precipitation through a drainage basin from surface runoff and other sources such as groundwater recharge, springs, an ...

Muddy Run (Spruce Run)
Muddy Run is a tributary of Spruce Run in Union County, Pennsylvania, in the United States. It is approximately long and flows through West Buffalo Township and Buffalo Township. The watershed of the stream has an area of . Part of the stream is designated as an impaired waterbody due to sedimentation and siltation from grazing-related agriculture. The majority of the watershed is forested, but there is also a considerable amount of agricultural land. A bridge has been constructed over the stream in the community of Mazeppa. Course Muddy Run begins near the base of Buffalo Mountain in West Buffalo Township. It flows east-southeast for several tenths of a mile before turning east-northeast and then east-southeast. Several tenths of a mile further downstream, the stream turns south-southeast for a few tenths of a mile before entering Buffalo Township and turning east for a few miles. It then turns southeast for several tenths of a mile before turning northeast. Several hundred f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tee Beam
A T-beam (or tee beam), used in construction, is a load-bearing structure of reinforced concrete, wood or metal, with a -shaped cross section. The top of the -shaped cross section serves as a flange or compression member in resisting compressive stresses. The web (vertical section) of the beam below the compression flange serves to resist shear stress. When used for highway bridges the beam incorporates reinforcing bars in the bottom of the beam to resist the tensile stresses which occur during bending. The T-beam has a big disadvantage compared to an I-beam (with shape) because it has no bottom flange with which to deal with tensile forces. One way to make a T-beam more efficient structurally is to use an inverted T-beam with a floor slab or bridge deck joining the tops of the beams. Done properly, the slab acts as the compression flange. History A T-beam is a structural element able to withstand large loads by resistance in the beam or by internal reinforcements. In some r ...

Mazeppa, Pennsylvania
Mazeppa is a populated place in Union County, Pennsylvania, United States, named in honor of Hetman Ivan Mazepa. History The settlement was originally named Union, and later called Boyertown, after early settlerSamuel Boyer (1804 - 1874) and his wife Sarah A name change was required by the Post Office in 1886, to eliminate confusion with Boyertown, Berks County. Professor Clement E. Edmunds, being familiar with Lord Byron's poem Mazeppa, proposed the new name. John Rentschler built a mill in 1788. Its name was later anglicized to Rengler, then became known as Johnson Mill after being purchased by Fred I. Johnson in 1930. It operated on water power Hydropower (from el, ὕδωρ, "water"), also known as water power, is the use of falling or fast-running water to produce electricity or to power machines.

Wagonmaker
A wainwright or cartwright is a trades person skilled in the making and repairing of wagons and carts.

Agriculture
Agriculture or farming is the practice of cultivating plants and livestock. Agriculture was the key development in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that enabled people to live in cities. The history of agriculture began thousands of years ago. After gathering wild grains beginning at least 105,000 years ago, nascent farmers began to plant them around 11,500 years ago. Sheep, goats, pigs and cattle were domesticated over 10,000 years ago. Plants were independently cultivated in at least 11 regions of the world. Industrial agriculture based on large-scale monoculture in the twentieth century came to dominate agricultural output, though about 2 billion people still depended on subsistence agriculture. The major agricultural products can be broadly grouped into foods, fibers, fuels, and raw materials (such as rubber). Food classes include cereals (grains), vegetables, fruits, cooking oils, meat, milk, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forest
A forest is an area of land dominated by trees. Hundreds of definitions of forest are used throughout the world, incorporating factors such as tree density, tree height, land use, legal standing, and ecological function. The United Nations' Food and Agriculture Organization (FAO) defines a forest as, "Land spanning more than 0.5 hectares with trees higher than 5 meters and a canopy cover of more than 10 percent, or trees able to reach these thresholds ''in situ''. It does not include land that is predominantly under agricultural or urban use." Using this definition, '' Global Forest Resources Assessment 2020'' (FRA 2020) found that forests covered , or approximately 31 percent of the world's land area in 2020. Forests are the predominant terrestrial ecosystem of Earth, and are found around the globe. More than half of the world's forests are found in only five countries (Brazil, Canada, China, Russia, and the United States). The largest share of forests (45 percent) are in th ...
