Masonry Dam
Masonry dams are dams made out of masonrymainly stone and brick, sometimes joined with mortar. They are either the gravity or the arch-gravity type. The largest masonry dam in the World is Nagarjuna Sagar Dam, Andhra Pradesh and Telangana, in India.

Masonry
Masonry is the craft of building a structure with brick, stone, or similar material, including mortar plastering which are often laid in, bound, and pasted together by mortar (masonry), mortar. The term ''masonry'' can also refer to the building units (stone, brick, etc.) themselves. The common materials of masonry construction are bricks and building stone, rock (geology), rocks such as marble, granite, and limestone, cast stone, concrete masonry unit, concrete blocks, glass brick, glass blocks, and adobe. Masonry is generally a highly durable form of construction. However, the materials used, the quality of the mortar and workmanship, and the pattern in which the units are assembled can substantially affect the durability of the overall masonry construction. A person who constructs masonry is called a mason or bricklayer. These are both classified as construction worker, construction trades.

Dams By Type
A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect or store water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions. The word ''dam'' can be traced back to Middle English, and before that, from Middle Dutch, as seen in the names of many old cities, such as Amsterdam and Rotterdam. Ancient dams were built in Mesopotamia and the Middle East for water control. The earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC. Egyptians also bu ...

Wicket Dam
A wicket dam, Chanoine wicket movable dam, or barrage à hausse mobile is a movable barrier across the width of a river that is used to hold up water and allow navigation under low-water conditions. When the wickets are lowered during high-water conditions, the river flow is unimpeded. A navigation lock is usually constructed alongside the wicket dam. The wicket dam was invented in the 19th century by , an engineer in the French . Construction of wicket dams primarily occurred in the late 19th and early 20th centuries. William Price Craighill completed the first of the moveable wicket dams built in the United States, after visiting France to study their use. A Chanoine wicket movable dam. was constructed by William Emery Merrill at Davis's Island, 5½ miles below Pittsburgh. From 1875 until the turn of the century, the United States Army Corps of Engineers constructed a series of 53 wicket dams to canalize the Ohio River The Ohio River () is a river in the United States.

Retaining Wall
Retaining walls are relatively rigid walls used for supporting soil laterally so that it can be retained at different levels on the two sides. Retaining walls are structures designed to restrain soil to a slope that it would not naturally keep to (typically a steep, near-vertical or vertical slope). They are used to bound soils between two different elevations often in areas of inconveniently steep terrain in areas where the landscape needs to be shaped severely and engineered for more specific purposes like hillside farming or roadway overpasses. A retaining wall that retains soil on the backside and water on the frontside is called a seawall or a bulkhead. Definition A retaining wall is designed to hold in place a mass of earth or the like, such as the edge of a terrace or excavation. The structure is constructed to resist the lateral pressure of soil when there is a desired change in ground elevation that exceeds the angle of repose of the soil. A basement wall is thus one k ...

Causeway
A causeway is a track, road or railway on the upper point of an embankment across "a low, or wet place, or piece of water". It can be constructed of earth, masonry, wood, or concrete. One of the earliest known wooden causeways is the Sweet Track in the Somerset Levels, England, which dates from the Neolithic age. Timber causeways may also be described as both boardwalks and bridges. Etymology When first used, the word ''causeway'' appeared in a form such as "causey way", making clear its derivation from the earlier form "causey". This word seems to have come from the same source by two different routes. It derives ultimately, from the Latin for heel, , and most likely comes from the trampling technique to consolidate earthworks. Originally, the construction of a causeway used earth that had been trodden upon to compact and harden it as much as possible, one layer at a time, often by slaves or flocks of sheep. Today, this work is done by machines. The same technique w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

New Croton Dam
The New Croton Dam is a masonry gravity dam forming the New Croton Reservoir, both parts of the New York City water supply system. It stretches across the Croton River near Croton-on-Hudson, New York, about north of New York City. Construction began in 1892 and was completed in 1906. Designed by Alphonse Fteley (1837–1903), the masonry dam is broad at its base and high from base to crest. At the time of its completion, it was the tallest dam in the world.Jackson, Donald C: ''Great American Bridges and Dams'', page 128. John Wiley and Sons, 1988.
