Inflatable Dam
Inflatable rubber dams are cylindrical rubber fabrics placed across channels, 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 raising existing dams, flood control, water retention for aquifer recharge, reducing or preventing salt water intrusion into fresh water areas, protect low-lyin ...

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 river 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. Etymology There is no single definition as to what constitutes a weir and one English dictionary simply defines a weir as a small dam, likely originating from Middle English ''were'', Old English ''wer'', derivative of root of ''werian,'' meaning "to defend, dam". Function Commonly, weirs are used to prevent flooding, measure water discharge, and help render rivers more navigable by boat. In some locations, the terms dam and weir are synonymous, but normally there is a clear distinction made between the structures. Usually, a dam is designed specifically to impound water behind ...

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 was ... [...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, between the town of 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, 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.

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 itself 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).

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 contains the IJsseloog, a kilometre-diameter circular pit in an artificial island, built to contain the to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Storm Surge Barrier
A flood barrier, surge barrier or storm surge barrier is a specific type of floodgate, designed to prevent a storm surge or spring tide from flooding the protected area behind the barrier. A surge barrier is almost always part of a larger flood protection system consisting of floodwalls, levees (also known as dikes), and other constructions and natural geographical features. Flood barrier may also refer to barriers placed around or at individual buildings to keep floodwaters from entering the buildings. Examples Delta Works The Delta Works in the Netherlands is the largest flood protection project in the world. This project consists of a number of surge barriers, the Oosterscheldekering being the largest surge barrier in the world, long. Other examples include the Maeslantkering, Haringvlietdam and the Hartelkering. Thames Barrier The Thames Barrier is the world's second largest movable flood barrier (after the Oosterscheldekering and the Haringvlietdam) and is locate ...
