Tiger Dam
Inflatable rubber dams are cylindrical rubber fabrics placed across channels, and streams and act as a weir or dam to raise the upstream water level when inflated. The membrane is a multi-layer fabric made of synthetic fibre (usually nylon) and rubberised on one or both sides. The fabric is flexible and yet exhibits good wear-resistance characteristics. A layer of stainless steel mesh or ceramic chips can be embedded in the surface layer to reduce or prevent vandal damage. The inflatable flexible membrane dams (IFMD, rubber dams, tiger dam) were developed in the 1950s by Norman M. Imbertson of the Los Angeles Department of Water and Power and were originally called fabridams. They are installed in stream and river beds, generally being bolted into a concrete foundation. They are used to divert water for irrigation, temporarily raise existing dams, flood control, water retention for aquifer recharge, reduce or prevent salt water intrusion into fresh water areas, protect low-lying ...

Weir
A weir or low-head dam is a barrier across the width of a river that alters the flow characteristics of water and usually results in a change in the height of the water level. Weirs are also used to control the flow of water for outlets of lakes, ponds, and reservoirs. There are many weir designs, but commonly water flows freely over the top of the weir crest before cascading down to a lower level. There is no single definition as to what constitutes a weir. ''Weir'' can also refer to the skimmer found in most in-ground swimming pools, which controls the flow of water pulled into the filtering system. Etymology The word likely originated from Middle English ''were'', Old English ''wer'', a derivative of the root of the verb ''werian,'' meaning "to defend, dam". The German cognate is ''Wehr'', which means the same as English weir. Function Commonly, weirs are used to prevent flooding, measure water discharge, and help render rivers more Navigability, navigable by boat. In ...

Shikellamy State Park
Shikellamy State Park is a Pennsylvania state park located at the confluence of the West Branch Susquehanna River and Susquehanna River in Pennsylvania. The park is divided into two sections. The older part, on a bluff on the western bank of the Susquehanna River, is the Shikellamy overlook in Union Township, Union County. The newer part is the marina on the southern end of Packer Island in Upper Augusta Township, Northumberland County. Packer's Island lies between the city of Sunbury and the borough of Northumberland at the confluence of the two branches of the river. History Shikellamy State Park is named in honor of Shikellamy, an Iroquois chief. Chief Shikellamy played a major role in the history of the frontier in Pennsylvania. He was a friend of the Native Americans and the American Colonists of the 18th century. Shikellamy's village was located near where the overlook section of the park is today. Shikellamy State Park was opened in two phases. The overlook w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Augusta (Pennsylvania)
The Adam T. Bower Memorial Dam (formerly known as the Sunbury Fabridam) is the world's longest inflatable dam. The dam is located just below the confluence of the Western and Main Branches of the Susquehanna River, in Upper Augusta Township, Northumberland County, Pennsylvania, Upper Augusta Township, between the town of Shamokin Dam, Pennsylvania, Shamokin Dam and the city of Sunbury, Pennsylvania. The dam is 2,100 feet (640 m) long. When it is raised in the summer time, it creates the 3,000 acre (12 km2) Lake Augusta (Pennsylvania), Lake Augusta, which is used for recreation. The dam and lake are part of Shikellamy State Park. In 2001, the dam was renamed for Adam T. Bower, Chief Clerk of the Pennsylvania House of Representatives from 1967–68 and Director of Services during the Pennsylvania Constitutional Convention of 1967-68, by Act 2001-5 of the Pennsylvania General Assembly.

Sunbury ( ) is a city and the county seat of Northumberland County in Pennsylvania, United States. Located in the Susquehanna Valley, Sunbury is positioned on the east bank of the Susquehanna River. Sunbury's roots stretch back to the early 18th century. As of the 2010 census, it had a population of 9,905. The city is one of the three principal cities in the larger Bloomsburg-Berwick-Sunbury, PA Combined Statistical Area. Sunbury is connected to inventor Thomas Edison. In 1883, the Hotel Edison became the first building in Sunbury to be illuminated by Edison's innovative three-wire electrical system. The hotel was later named in honor of Edison. Sunbury is home to the Beck House and the Northumberland County Courthouse. The Sunbury Historic District is listed on the National Register of Historic Places.

Shamokin Dam, Pennsylvania
Shamokin Dam is a borough in Snyder County, Pennsylvania, United States. The population was 1,647 at the 2020 census. "Shamokin" , or "Shahëmokink" in the Delaware language, and Schahamokink in another Algonquian language, means "place of eels." The borough name is also derived from a dam that was built across the Susquehanna River in the 19th century. The dam supported steamboat ferries run by Ira T. Clement, which transported goods and people between Shamokin Dam and the city of Sunbury on the Northumberland County side of the river. These ferries operated from 1772 until the Bainbridge Street Bridge was built in 1907. The dam also provided water to the Susquehanna Division of the Pennsylvania Canal System, which was constructed on the western bank of the river. The dam was destroyed by ice in March 1904. Shamokin Dam is distinct from the city of Shamokin, Pennsylvania, which is located about 14 miles to the east in Northumberland County. Geography According to the Un ...

Adam T
Adam is the name given in Genesis 1–5 to the first human. Adam is the first human-being aware of God, and features as such in various belief systems (including Judaism, Christianity, Gnosticism and Islam). According to Christianity, Adam sinned in the Garden of Eden by eating from the tree of the knowledge of good and evil. This action introduced death and sin into the world. This sinful nature infected all his descendants, and led humanity to be expelled from the Garden. Only through the crucifixion of Jesus, humanity can be redeemed. In Islam, Adam is considered ''Khalifa'' (خليفة) (successor) on earth. This is understood to mean either that he is God's deputy, the initiation of a new cycle of sentient life on earth, or both. Similar to the Biblical account, the Quran has Adam placed in a garden where he sins by taking from the Tree of Immortality, so loses his abode in the garden. When Adam repents from his sin, he is forgiven by God. This is seen as a guidance for h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Zwarte Water
The Zwarte Water ("Black Water") is a river in the Dutch province of Overijssel. It is formed just south of the city of Zwolle when two streams, the Soestwetering and the Nieuwe Wetering, merge. The Zwarte Water then flows north through Zwolle, bends to the northeast, takes in the Vecht near Hasselt and flows past the town of Zwartsluis to discharge in the Zwarte Meer ("Black Lake", connected to the IJsselmeer lake) near Genemuiden. Contrary to popular belief, the Zwarte Water is not an IJssel branch, nor is it another name for the Vecht. The river is, however, connected to the IJssel by two canal Canals or artificial waterways are waterways or engineered channels built for drainage management (e.g. flood control and irrigation) or for conveyancing water transport vehicles (e.g. water taxi). They carry free, calm surface ...s, the Willemsvaart (dug in the early nineteenth century, now disused) and the Zwolle-IJssel Canal. References {{reflist R ...

Ketelmeer
The Ketelmeer is the tongue of the IJsselmeer into which the River IJssel drains, it is situated between the polders Noordoostpolder (North-east Polder) and Oostelijk Flevoland (East Flevoland), and connects the river IJssel to the IJsselmeer. It is one of the bordering lakes, a continuous body of water which separate Flevoland from the Noordostpolder and the ancient lands of the provinces of Gelderland and Utrecht. The Ketelmeer covers an area of 3500 hectares, most of which is in the province of Flevoland, but the river delta of the IJssel is in province of Overijssel. It was carved out from the Zuiderzee by the construction of the polders of Noordoostpolder and Flevoland, between which it lies. It is via Ketelmeer that the IJsselmeer connects to the Zwarte Meer and the Veluwemeer, the strip of water which separates Flevoland from the coast of the mainland. The Ketelmeer borders two '' buurtschappen'', on the opposite sides of the lake: Ketelhaven on the south and S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
