Reversing Falls
The Reversing Falls are a series of rapids on the Saint John River located in Saint John, New Brunswick, Canada, where the river runs through a narrow gorge before emptying into the Bay of Fundy. The semidiurnal tides of the bay force the flow of water to reverse against the prevailing current when the tide is high, although in the spring freshet, this is frequently surpassed by the downstream volume of water. The rapids, or "falls", are created by a series of underwater ledges which roil the water in either direction, causing a significant navigation hazard, despite the depth of water. As a result, vessels wishing to enter or exit from the river must wait for slack tide. The Reversing Falls have also been an important industrial site for over a century. The Canadian Pacific Railway constructed the Reversing Falls Railway Bridge in 1885 and this structure was replaced in 1922; it is currently used by the New Brunswick Southern Railway. The railway bridge crosses the gorge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pembroke, Maine
Pembroke is a town in Washington County, Maine, United States. The population was 788 at the 2020 census. The town is home to a reversing falls on Mahar's Point. History Called ''Pennamaquan'' by the Passamaquoddy Indians, the area was settled about 1774 as part of Dennysville. It was set off and incorporated on February 4, 1832 by the legislature, which named it after Pembroke in Wales, a community with a history of wooden shipbuilding stretching back to the Middle Ages. With one of the finest harbors in Maine, Pembroke too became a shipbuilding center. Vessels were constructed here as early as 1825. By 1859, when the population was 1,712, there were seven shipyards operating. Most schooners constructed here were used either by the coasting trade or fisheries. Pembroke also had a stone factory, three sawmills, one gristmill, four shingle mills and four lath machines. Near the head of tide stood the Pembroke Iron Company, established in 1832 and by 1856 producing almost ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Saint John River (Bay Of Fundy)
The Saint John River (french: Fleuve Saint-Jean; Maliseet-Passamaquoddy: ''Wolastoq'') is a long river that flows from Northern Maine into Canada, and runs south along the western side of New Brunswick, emptying into the Atlantic Ocean in the Bay of Fundy. Eastern Canada's longest river, its drainage basin is one of the largest on the east coast at about . A part of the border between New Brunswick and Maine follows 130 km (80 miles) of the river. A tributary forms 55 km (35 miles) of the border between Quebec and Maine. New Brunswick settlements through which it passes include, moving downstream, Edmundston, Fredericton, Oromocto, and Saint John. It is regulated by hydro-power dams at Mactaquac, Beechwood, and Grand Falls, New Brunswick. Hydronym Samuel de Champlain visited the mouth of the river on the feast day of John the Baptist in 1604 and renamed it the Rivière Saint-Jean or Saint John River in English.

Waterfalls Of New Brunswick
A waterfall is a point in a river or stream where water flows over a vertical drop or a series of steep drops. Waterfalls also occur where meltwater drops over the edge of a tabular iceberg or ice shelf. Waterfalls can be formed in several ways, but the most common method of formation is that a river courses over a top layer of resistant bedrock before falling on to softer rock, which erodes faster, leading to an increasingly high fall. Waterfalls have been studied for their impact on species living in and around them. Humans have had a distinct relationship with waterfalls for years, travelling to see them, exploring and naming them. They can present formidable barriers to navigation along rivers. Waterfalls are religious sites in many cultures. Since the 18th century they have received increased attention as tourist destinations, sources of hydropower, andparticularly since the mid-20th centuryas subjects of research.

Whitewater Kayaking
Whitewater kayaking is an adventure sport where a river is navigated in a decked kayak. Whitewater kayaking includes several styles. River running; where the paddler follows a river and paddles rapids as they travel. Creeking usually involving smaller, steeper, and more technical waterways. Creek boats tend to be short but high volume to allow for manoeuvrability while maintaining buoyancy. Slalom requires paddlers to navigate through "gates" (coloured poles hanging above the river). Slalom is the only whitewater event to be in the Olympics. Play boating involves staying on one feature of the river and is more artistic than the others. Squirt boating uses low-volume boats (usually made specifically for the paddler) to perform special moves in whitewater features. History Paddling on rivers, lakes and oceans is as old as the Stone Age. The raft, the catamaran, the canoe and the kayak evolved depending on the needs and environment of the indigenous peoples in different parts of ...

Jet Boat
A jetboat is a boat propelled by a jet of water ejected from the back of the craft. Unlike a powerboat or motorboat that uses an external propeller in the water below or behind the boat, a jetboat draws the water from under the boat through an intake and into a pump-jet inside the boat, before expelling it through a nozzle at the stern. The modern jetboat was developed by New Zealand engineer Sir William Hamilton in the mid-1950s. His goal was a boat to run up the fast-flowing rivers of New Zealand that were too shallow for propellers. Previous attempts at waterjet propulsion had very short lifetimes, generally due to the inefficient design of the units and the fact that they offered few advantages over conventional propellers. Unlike these previous waterjet developments, such as Campini's and the Hanley Hydrojet, Hamilton had a specific need for a propulsion system to operate in very shallow water, and the waterjet proved to be the ideal solution.

Pulp And Paper
The pulp and paper industry comprises companies that use wood as raw material and produce pulp, paper, paperboard and other cellulose-based products. Manufacturing process The pulp is fed to a paper machine where it is formed as a paper web and the water is removed from it by pressing and drying. Pressing the sheet removes the water by force. Once the water is forced from the sheet, a special kind of felt, which is not to be confused with the traditional one, is used to collect the water. Whereas, when making paper by hand, a blotter sheet is used instead. Drying involves using air or heat to remove water from the paper sheets. In the earliest days of paper making, this was done by hanging the sheets like laundry. In more modern times, various forms of heated drying mechanisms are used. On the paper machine, the most common is the steam heated can dryer. History of the paper industry Papermaking as a craft is ancient, and for centuries it used various fibers, mainly grasses ...

Foundry
A foundry is a factory that produces metal castings. Metals are cast into shapes by melting them into a liquid, pouring the metal into a mold, and removing the mold material after the metal has solidified as it cools. The most common metals processed are aluminum and cast iron. However, other metals, such as bronze, brass, steel, magnesium, and zinc, are also used to produce castings in foundries. In this process, parts of desired shapes and sizes can be formed. Foundries are one of the largest contributors to the manufacturing recycling movement, melting and recasting millions of tons of scrap metal every year to create new durable goods. Moreover, many foundries use sand in their molding process. These foundries often use, recondition, and reuse sand, which is another form of recycling. Process In metalworking, casting involves pouring liquid metal into a mold, which contains a hollow cavity of the desired shape, and then allowing it to cool and solidify. The solidified pa ...

Reversing Falls Bridge
The Reversing Falls Bridge is a two-lane bridge crossing the Saint John River at Saint John, New Brunswick, Canada. It carries New Brunswick Route 100 (Bridge Road) across the river and there is no toll for its use. History The Reversing Falls rapids are a notoriously dangerous stretch of water passing through a gorge which creates a chasm through the middle of the Saint John metropolitan region. Prior to construction of the first bridge in 1853, ferries were used to connect both sides of the river in the city. The first bridge was a suspension bridge, built by Joseph Tomlinson III, measured 190 m in span. Its replacement, the current steel arch structure or Saint John Highway Arch Bridge (designed by Philip Louis Pratley), was opened to public use alongside the original in 1915. Both structures have shared the site of this crossing with the Reversing Falls Railway Bridge since 1885. It is also known as the floating bridge. Until the 1940s, the Reversing Falls Bridge als ...

Reversing Falls Railway Bridge
The Reversing Falls Railway Bridge is the name given to two different steel truss bridges crossing the Saint John River at the same location in Saint John, New Brunswick, Canada. The original bridge was constructed in 1885 immediately upstream of a highway crossing known as the Reversing Falls Bridge. Measuring in length, the railway bridge carried a single-track main line. It was constructed by the Saint John Bridge and Railroad Extension Company which was a municipal-owned corporation established to connect two separated sections of the former European and North American Railway project. The eastern section of the E&NAR was merged into the Intercolonial Railway following Confederation while the western section was acquired by the New Brunswick Railway (NBR). The Saint John Bridge and Railroad Extension Company was acquired by the NBR following the construction of the bridge. The NBR was purchased by the Canadian Pacific Railway in 1890.

Reversing Falls Park
Reversing Falls Park is a municipal park in Pembroke, Maine. It is located at Mahar Point, the northern point of a narrows separating Dennys Bay from Cobscook Bay in far eastern Maine. The narrows are subject to a reversal of current twice a day, owing to the area's unusually high tides. In addition to viewing this action, the park is also well suited for wildlife viewing. The area in the park vicinity is also archaeologically sensitive, as the site of Native American settlements in the area's prehistory. It was listed on the National Register of Historic Places in 1990.
