Seabrook Floodgate
The Inner Harbor Navigation Canal (IHNC) Seabrook Floodgate Structure is a flood barrier in the Industrial Canal in New Orleans, Louisiana. The floodgate is designed to protect the Industrial Canal and the surrounding areas from a storm surge from Lake Pontchartrain. It consists of two wide vertical lift gates and a wide sector gate. The building of the floodgate was authorized by Congress in 2006 and operated in tandem with the Lake Borgne Surge Reduction Barrier to reduce the risk of storm surge damage to some of the New Orleans region's most vulnerable areas – New Orleans East, metro New Orleans, the Ninth Ward, Gentilly, and St. Bernard Parish. Design The Seabrook Floodgate Structure consists of a sector gate and two vertical lift gates approximately south of the Senator Ted Hickey Bridge with flood wall tie-ins on the east and west sides. Other components of the Seabrook Floodgate project include added T-walls and the replacement of the existing Alabama Great Souther ...

Buildings And Structures In New Orleans
A building or edifice is an enclosed structure with a roof, walls and windows, usually standing permanently in one place, such as a house or factory. Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for numerous factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the concept, see ''Nonbuilding structure'' for contrast. Buildings serve several societal needs – occupancy, primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical separation of the human habitat (a place of comfort and safety) from the ''outside'' (a place that may be harsh and harmful at times). buildings have been objects or canvasses of much artistic expression. In recent years, interest in sustainable planning and building practi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flood Barriers
A flood is an overflow of water ( or rarely other fluids) that submerges land that is usually dry. In the sense of "flowing water", the word may also be applied to the inflow of the tide. Floods are of significant concern in agriculture, civil engineering and public health. Human changes to the environment often increase the intensity and frequency of flooding. Examples for human changes are land use changes such as deforestation and removal of wetlands, changes in waterway course or flood controls such as with levees. Global environmental issues also influence causes of floods, namely climate change which causes an intensification of the water cycle and sea level rise. For example, climate change makes extreme weather events more frequent and stronger. This leads to more intense floods and increased flood risk. Natural types of floods include river flooding, groundwater flooding coastal flooding and urban flooding sometimes known as flash flooding. Tidal flooding may inclu ...

Hurricane Katrina
Hurricane Katrina was a powerful, devastating and historic tropical cyclone that caused 1,392 fatalities and damages estimated at $125 billion in late August 2005, particularly in the city of New Orleans and its surrounding area. It is tied with Hurricane Harvey as being the List of the costliest tropical cyclones, costliest tropical cyclone in the Atlantic basin. Katrina was the twelfth tropical cyclone, the fifth hurricane, and the third major hurricane of the 2005 Atlantic hurricane season. It was also the fourth-most intense Atlantic hurricane to make landfall in the contiguous United States, gauged by barometric pressure. Katrina formed on August 23, 2005, with the merger of a tropical wave and the remnants of a tropical depression. After briefly weakening to a Tropical cyclone, tropical storm over south Florida, Katrina entered the Gulf of Mexico on August 26 and Rapid intensification, rapidly intensified to a Saffir–Simpson scale, Category 5 hurricane befo ...

Hurricane Ida
Hurricane Ida was a deadly and extremely destructive tropical cyclone in 2021 that became the second-most damaging and intense hurricane to make landfall in the U.S. state of Louisiana on record, behind Hurricane Katrina in 2005. In terms of maximum sustained winds at landfall (), Ida tied 2020's Hurricane Laura and the 1856 Last Island hurricane as the strongest on record to hit Louisiana. The remnants of the storm also caused a Hurricane Ida tornado outbreak, tornado outbreak and catastrophic flooding across the Northeastern United States. The ninth tropical cyclone naming, named storm, fourth hurricane, and second Saffir-Simpson scale, major hurricane of the 2021 Atlantic hurricane season, Ida originated from a tropical wave in the Caribbean Sea on August 23. On August 26, the wave developed into a tropical depression, which organized further and became Tropical Storm Ida later that day, near Grand Cayman. Amid favorable conditions, Ida intensified into a hurricane ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hurricane Isaac (2012)
Hurricane Isaac was a deadly and destructive tropical cyclone that landfall (meteorology), came ashore in the U.S. state of Louisiana during August 2012. The ninth tropical cyclone naming, named storm and fourth hurricane of the 2012 Atlantic hurricane season, annual hurricane season, Isaac originated from a tropical wave that moved off the west coast of Africa on August 16. Tracking generally west, a broad low-pressure area, area of low pressure developed along the wave axis the next day, and the disturbance developed into a tropical depression early on August 21 while several hundred miles east of the Lesser Antilles. The system intensified into a tropical storm shortly thereafter, but high wind shear initially prevented much change in strength. Isaac tracked between Guadeloupe and Dominica late on August 22, and then turned towards the west-northwest and entered a region favorable for intensification; it passed over Haiti and Cuba at strong tropical storm str ...

Cofferdam
A cofferdam is an enclosure built within a body of water to allow the enclosed area to be pumped out or drained. This pumping creates a dry working environment so that the work can be carried out safely. Cofferdams are commonly used for construction or repair of permanent dams, oil platforms, bridge piers, etc., built within water. These cofferdams are usually welded steel structures, with components consisting of Larssen sheet piling, sheet piles, Wale (ship part), wales, and cross timber framing, braces. Such structures are usually dismantled after the construction work is completed. The origin of the word comes from ''coffer'' (originally from Latin meaning 'basket') and ''dam'' from Proto-Germanic meaning 'barrier across a stream of water to obstruct its flow and raise its level'). #Naval architecture, The term is also used in naval architecture, to refer to a space between two watertight bulkheads or decks within a ship. Uses For dam construction, two cofferdams ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boat Launch
A slipway, also known as boat ramp or launch or boat deployer, is a ramp on the shore by which ships or boats can be moved to and from the water. They are used for building and repairing ships and boats, and for launching and retrieving small boats on trailers towed by automobiles and flying boats on their undercarriage. The nautical terms ways and skids are alternative names for slipway. A ship undergoing construction in a shipyard is said to be ''on the ways''. If a ship is scrapped there, she is said to be ''broken up in the ways''. As the word "slip" implies, the ships or boats are moved over the ramp, by way of crane or fork lift. Prior to the move the vessel's hull is coated with grease, which then allows the ship or boat to "slip" off the ramp and progress safely into the water. Slipways are used to launch (newly built) large ships, but can only dry-dock or repair smaller ships. Pulling large ships against the greased ramp would require too much force. Therefore, f ...

Flood Wall
A floodwall is a freestanding, permanent, engineered structure designed to prevent encroachment of floodwaters. Floodwalls are mainly used on locations where space is scarce, such as cities or where building levees or dikes (dykes) would interfere with other interests, such as existing buildings, historical architecture or commercial use of embankments. Floodwalls are nowadays mainly constructed from pre-fabricated concrete elements. Floodwalls often have coupures, which are large openings to provide passage of traffic except during periods of flooding, when they are closed. As a floodwalls mostly consist of relatively short elements compared to dikes, the connections between the elements are critical to prevent the failure of the floodwall. The substantial costs of floodwalls can be justified by the value of commercial property thus protected from damage caused by flooding. Floodwalls are sometimes bad for ecosystems. Floodwalls are almost always built in cities. See als ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
