Effects Of Hurricane Katrina In New Orleans
As the center of Hurricane Katrina passed southeast of New Orleans on August 29, 2005, winds downtown were in the Category 1 range with frequent intense gusts. The storm surge caused approximately 23 breaches in the drainage canal and navigational canal levees and flood walls. As mandated in the Flood Control Act of 1965, responsibility for the design and construction of the city’s levees belongs to the United States Army Corps of Engineers and responsibility for their maintenance belongs to the Orleans Levee District. The failures of levees and flood walls during Katrina are considered by experts to be the worst engineering disaster in the history of the United States. By August 31, 2005, 80% of New Orleans was flooded, with some parts under of water. The famous French Quarter and Garden District escaped flooding because those areas are above sea level. The major breaches included the 17th Street Canal levee, the Industrial Canal levee, and the London Avenue Canal f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hurricane Georges
Hurricane Georges () was a powerful and long-lived tropical cyclone which caused severe destruction as it traversed the Caribbean and Gulf of Mexico in September 1998, making seven landfalls along its path. Georges was the seventh tropical storm, fourth hurricane, and second major hurricane of the 1998 Atlantic hurricane season. It became one of the most destructive storm of the season, the costliest Atlantic hurricane since Hurricane Andrew in 1992 and remained the costliest until Hurricane Charley in 2004, and the deadliest since Hurricane Gordon in 1994. Georges killed 615 people, mainly on the island of Hispaniola, caused extensive damage resulting in just under $10 billion (US dollars in 1998) in damages and leaving nearly 500,000 people homeless in St. Kitts and Nevis, Puerto Rico, Hispaniola and Cuba. The hurricane made landfall in at least six countries (Antigua and Barbuda, St. Kitts and Nevis, Haiti, the Dominican Republic, Cuba, and the United States), ...

Orleans Parish, Louisiana
Orleans Parish (; ) is a parish of the U.S. state of Louisiana. Since 1870, the parish has been coextensive with the city of New Orleans, and the parish and city are largely governed as a single consolidated city. History On April 10, 1805, the Territory of Orleans was divided into 12 counties, including Orleans County. On April 14, 1807, the territory was also divided into 19 civil parishes while keeping the previous system of counties intact. Based on the boundaries and names of earlier ecclesiastical parishes, Orleans County was divided into Orleans, St. Bernard, and Plaquemines parishes, with New Orleans inside the Orleans Parish limits. The county remained responsible for elections and taxation, while the parishes took over responsibility for civil, criminal, probate, and other judicial matters. The system of counties was never explicitly abolished, but the Louisiana Constitution of 1845 dropped any reference to counties and gave their powers to the parishes. At ...

LIDAR
Lidar (, also LIDAR, an acronym of "light detection and ranging" or "laser imaging, detection, and ranging") is a method for determining ranging, ranges by targeting an object or a surface with a laser and measuring the time for the reflected light to return to the receiver. Lidar may operate in a fixed direction (e.g., vertical) or it may scan multiple directions, in a special combination of 3-D scanning and laser scanning. Lidar has terrestrial, airborne, and mobile applications. It is commonly used to make high-resolution maps, with applications in surveying, geodesy, geomatics, archaeology, geography, geology, geomorphology, seismology, forestry, atmospheric physics, laser guidance, airborne laser swathe mapping (ALSM), and Mars Orbiter Laser Altimeter, laser altimetry. It is used to make digital 3D modeling, 3-D representations of areas on the Earth's surface and ocean bottom of the intertidal and near coastal zone by varying the wavelength of light. It has also been in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Subsidence
Subsidence is a general term for downward vertical movement of the Earth's surface, which can be caused by both natural processes and human activities. Subsidence involves little or no horizontal movement, which distinguishes it from slope movement. Processes that lead to subsidence include dissolution of underlying carbonate rock by groundwater; gradual compaction of sediments; withdrawal of fluid lava from beneath a solidified crust of rock; mining; pumping of subsurface fluids, such as groundwater or petroleum; or warping of the Earth's crust by tectonic forces. Subsidence resulting from tectonic deformation of the crust is known as tectonic subsidence and can create accommodation for sediments to accumulate and eventually lithify into sedimentary rock. Ground subsidence is of global concern to geologists, geotechnical engineers, surveyors, engineers, urban planners, landowners, and the public in general.National Research Council, 1991.

Hurricane Betsy
Hurricane Betsy was an intense, deadly and destructive tropical cyclone that brought widespread damage to areas of Florida, the Bahamas, and the central United States Gulf Coast in September 1965. The storm's erratic nature, coupled with its intensity and minimal preparation time contributed to making Betsy the first tropical cyclone in the Atlantic basin to accrue at least $1 billion in damage. While the storm primarily affected areas of southern Florida and Louisiana, lesser effects were felt in the Bahamas and as far inland in the United States as the Ohio River Valley. Betsy began as a tropical depression north of French Guiana on August 27, and strengthened as it moved in a general northwesterly direction. After executing a slight anticyclonic loop north of the Bahamas, Betsy proceeded to move through areas of south Florida on September 8, causing extensive crop damage. After emerging into the Gulf of Mexico, the cyclone strengthened and reached its ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Pontchartrain
Lake Pontchartrain ( ; ) is an estuary located in southeastern Louisiana in the United States. It covers an area of with an average depth of . Some shipping channels are kept deeper through dredging. It is roughly oval in shape, about from west to east and from south to north. In descending order of area, the estuary is located in parts of six Louisiana parishes: St. Tammany, Orleans, Jefferson, St. John the Baptist, St. Charles, and Tangipahoa. The water boundaries were defined in 1979 (see list of parishes in Louisiana). The estuary is crossed by the Lake Pontchartrain Causeway, the longest continuous bridge over water in the world. A power line also crosses the estuary. Its towers stand on caissons in Lake Pontchartrain, and its length can be used to visually demonstrate the curvature of the Earth. Toponymy Lake Pontchartrain was named for Louis Phélypeaux, Comte-de-Pontchartrain. He was the French Minister of the Marine, Chancellor, and Controller-General o ...
