Laurel Run (Huntington Creek)
Laurel Run (also known as Laurel Run Creek) is a tributary of Huntington Creek, in Luzerne County, Pennsylvania, in the United States. It is approximately long and flows through Ross Township. The watershed of the stream has an area of . Wild trout naturally reproduce in the stream. The surficial geology in the area mainly consists of Wisconsinan Till, Wisconsinan Ice-Contact Stratified Drift, and bedrock consisting of sandstone and shale. The stream is designated as a Least Disturbed Stream. Course Laurel Run begins in a valley in Ross Township. It flows west-southwest for nearly a mile alongside Dobson Road before turning southwest for a short distance. The stream then turns west-southwest again for several tenths of a mile before crossing State Route 4024 and reaching its confluence with Huntington Creek. Laurel Run joins Huntington Creek upstream of its mouth. Geography and geology The elevation near the mouth of Laurel Run is above sea level. The elevation of the stre ...

Gravel
Gravel is a loose aggregation of rock fragments. Gravel occurs naturally throughout the world as a result of sedimentary and erosive geologic processes; it is also produced in large quantities commercially as crushed stone. Gravel is classified by particle size range and includes size classes from granule- to boulder-sized fragments. In the Udden-Wentworth scale gravel is categorized into granular gravel () and pebble gravel (). ISO 14688 grades gravels as fine, medium, and coarse, with ranges 2–6.3 mm to 20–63 mm. One cubic metre of gravel typically weighs about 1,800 kg (or a cubic yard weighs about 3,000 lb). Gravel is an important commercial product, with a number of applications. Almost half of all gravel production is used as aggregate for concrete. Much of the rest is used for road construction, either in the road base or as the road surface (with or without asphalt or other binders.) Naturally occurring porous gravel deposits have a ...

Bridge
A bridge is a structure built to span a physical obstacle (such as a body of water, valley, road, or rail) without blocking the way underneath. It is constructed for the purpose of providing passage over the obstacle, which is usually something that is otherwise difficult or impossible to cross. There are many different designs of bridges, each serving a particular purpose and applicable to different situations. Designs of bridges vary depending on factors such as the function of the bridge, the nature of the terrain where the bridge is constructed and anchored, and the material used to make it, and the funds available to build it. The earliest bridges were likely made with fallen trees and stepping stones. The Neolithic people built boardwalk bridges across marshland. The Arkadiko Bridge (dating from the 13th century BC, in the Peloponnese) is one of the oldest arch bridges still in existence and use. Etymology The '' Oxford English Dictionary'' traces the origin of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
County Commission
A county commission (or a board of county commissioners) is a group of elected officials (county commissioners) collectively charged with administering the county government in some states of the United States; such commissions usually comprise three to five members. In some counties within Georgia, however, a sole commissioner holds the authority of the commission. In parts of the United States, alternative terms such as County Board of Supervisors or County Council may be used in lieu of, but generally synonymous to, a County Commission. However, in some jurisdictions there may be distinct differences between a County Commission and other similarly titled bodies. For example, a County Council may differ from a County Commission by containing more members or by having a Council-Manager form of government. In Indiana, every county, except Marion, which is consolidated with Indianapolis, has both a County Commission and a County Council, with the County Commission having admi ...

Geographic Names Information System
The Geographic Names Information System (GNIS) is a database of name and locative information about more than two million physical and cultural features throughout the United States and its territories, Antarctica, and the associated states of the Marshall Islands, Federated States of Micronesia, and Palau. It is a type of gazetteer. It was developed by the United States Geological Survey (USGS) in cooperation with the United States Board on Geographic Names (BGN) to promote the standardization of feature names. Data were collected in two phases. Although a third phase was considered, which would have handled name changes where local usages differed from maps, it was never begun. The database is part of a system that includes topographic map names and bibliographic references. The names of books and historic maps that confirm the feature or place name are cited. Variant names, alternatives to official federal names for a feature, are also recorded. Each feature receives a per ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Point Source Pollution
A point source of pollution is a single identifiable source of air, water, thermal, noise or light pollution. A point source has negligible extent, distinguishing it from other pollution source geometries (such as nonpoint source or area source). The sources are called ''point sources'' because in mathematical modeling, they can be approximated as a mathematical point to simplify analysis. Pollution point sources are identical to other physics, engineering, optics, and chemistry point sources and include: * Air pollution from an industrial source (rather than an airport or a road, considered a line source, or a forest fire, which is considered an area source, or volume source) *Water pollution from factories, power plants, municipal sewage treatment plants and some farms (''see'' concentrated animal feeding operation). The U.S. Clean Water Act also defines municipal separate storm sewer systems and industrial stormwater discharges (such as construction sites) as point sources. ...

Riparian Buffer
A riparian buffer or stream buffer is a vegetated area (a "buffer strip") near a stream, usually forested, which helps shade and partially protect the stream from the impact of adjacent land uses. It plays a key role in increasing water quality in associated streams, rivers, and lakes, thus providing environmental benefits. With the decline of many aquatic ecosystems due to agriculture, riparian buffers have become a very common conservation practice aimed at increasing water quality and reducing pollution. Benefits Riparian buffers act to intercept sediment, nutrients, pesticides, and other materials in surface runoff and reduce nutrients and other pollutants in shallow subsurface water flow. They also serve to provide habitat and wildlife corridors in primarily agricultural areas. They can also be key in reducing erosion by providing stream bank stabilization. Large scale results have demonstrated that the expansion of riparian buffers through the deployment of plantations ... [...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 ...

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] |
Pennsylvania Natural Heritage Program
Founded in 1982, the Pennsylvania Natural Heritage Program (PNHP) gathers and manages information regarding the status and location of the Commonwealth of Pennsylvania’s rare species and habitats and native natural communities. PHNP's goal is to build, maintain, and provide accurate and accessible ecological information needed for conservation, development planning and natural resource management. PNHP works with the Western Pennsylvania Conservancy, Pennsylvania Department of Conservation and Natural Resources (DCNR), the Pennsylvania Fish and Boat Commission, and the Pennsylvania Game Commission. One important initiative within the Heritage Program is the County Natural Heritage Inventory, which conducts county-wide inventories of threatened and endangered species as well as important natural areas. At present, completed county inventories are available for 57 counties and the remaining 10 are in progress. In addition, PNHP will return to counties and perform updates to ensu ...
