IHNC Lake Borgne Surge Barrier
The Inner Harbor Navigation Canal Lake Borgne Surge Barrier is a storm surge barrier constructed near the confluence of and across the Gulf Intracoastal Waterway (GIWW) and the Mississippi River Gulf Outlet (MRGO) near New Orleans. The barrier runs generally north-south from a point just east of Michoud Canal on the north bank of the GIWW and just south of the existing Bayou Bienvenue flood control structure. Navigation gates where the barrier crosses the GIWW and Bayou Bienvenue can be worked to reduce the risk of storm surge coming from Lake Borgne and/or the Gulf of Mexico. Another navigation gate ( Seabrook Floodgate) has been constructed in the Seabrook vicinity, where the IHNC meets Lake Pontchartrain, to block a storm surge from entering the IHNC from the Lake. Purpose The Inner Harbor Navigation Canal (IHNC) surge barrier was authorized by Congress in 2006. The barrier is designed to reduce the risk of storm damage to some of the region's most vulnerable areas - New Orlea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gulf Intracoastal Waterway
The Gulf Intracoastal Waterway is the portion of the Intracoastal Waterway located along the Gulf Coast of the United States. It is a navigable inland waterway running approximately from Carrabelle, Florida, to Brownsville, Texas. The waterway provides a channel with a controlling depth of , designed primarily for barge transportation. Although the U.S. government proposals for such a waterway were made in the early 19th century, the Gulf Intracoastal Waterway was not completed until 1949. EHL & WHL mileages Locations along the Gulf Intracoastal Waterway are defined in terms of statute miles (as opposed to nautical miles, in which most marine routes are measured) east and west of Harvey Lock, a navigation lock in the New Orleans area located at . The Hathaway Bridge in Panama City, Florida, for example, is at mile 284.6 EHL (East of Harvey Lock). The Queen Isabella Causeway Bridge at South Padre Island is at mile 665.1 WHL (West of Harvey Lock). Connecting waterways Th ...

New Orleans Metropolitan Area
The New Orleans metropolitan area, designated the New Orleans–Metairie metropolitan statistical area by the U.S. Office of Management and Budget, or simply Greater New Orleans (french: Grande Nouvelle-Orléans, es, Gran Nueva Orleans), is a metropolitan statistical area designated by the United States Census Bureau encompassing eight Louisiana parishes—the equivalent of counties in other U.S. states—centered on the city of New Orleans. The population of Greater New Orleans was 1,271,845 in 2020, up from 1,189,166 at the 2010 United States census. According to 2017 census estimates, the broader New Orleans–Metairie–Hammond combined statistical area (CSA) had a population of 1,510,562. The New Orleans metropolitan area was hit by Hurricane Katrina—once a category 5 hurricane, but a category 3 storm at landfall—on August 29, 2005. Within the city of New Orleans proper, multiple breaches and structural failures occurred in the system of levees and flood walls designed ...

Hurricane Isaac (2012)
Hurricane Isaac was a deadly and destructive tropical cyclone that came ashore in the U.S. state of Louisiana during August 2012. The ninth named storm and fourth hurricane of the 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 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 strength. A ridge of high pressure to Isaac's north intensified and turned it westward over the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hurricane Katrina
Hurricane Katrina was a destructive Category 5 Atlantic hurricane that caused over 1,800 fatalities and $125 billion in damage in late August 2005, especially in the city of New Orleans and the surrounding areas. It was at the time the costliest tropical cyclone on record and is now tied with 2017's Hurricane Harvey. The storm was the twelfth tropical cyclone, the fifth hurricane, and the third major hurricane of the 2005 Atlantic hurricane season, as well as the fourth-most intense Atlantic hurricane on record to make landfall in the contiguous United States. Katrina originated on August 23, 2005, as a tropical depression from the merger of a tropical wave and the remnants of Tropical Depression Ten. Early the following day, the depression intensified into a tropical storm as it headed generally westward toward Florida, strengthening into a hurricane two hours before making landfall at Hallandale Beach on August 25. After briefly weakening to tropical storm strength o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flood Wall
A flood wall (or floodwall) is a primarily vertical artificial barrier designed to temporarily contain the waters of a river or other waterway which may rise to unusual levels during seasonal or extreme weather events. Flood walls 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. Flood walls are nowadays mainly constructed from pre-fabricated concrete elements. Flood walls often have floodgates which are large openings to provide passage except during periods of flooding, when they are closed. As a flood walls mostly consist of relatively short elements compared to dikes, the connections between the elements are critical to prevent the failure of the flood wall. The substantial costs of flood walls can be justified by the value of commercial property thus protected from damage caused by flooding. ...

Groundbreaking
Groundbreaking, also known as cutting, sod-cutting, turning the first sod, or a sod-turning ceremony, is a traditional ceremony in many cultures that celebrates the first day of construction for a building or other project. Such ceremonies are often attended by dignitaries such as politicians and businesspeople. The actual shovel used during the groundbreaking is often a special ceremonial shovel, sometimes colored gold, meant to be saved for subsequent display and may be engraved. In other groundbreaking ceremonies, a bulldozer is used instead of a shovel to mark the first day of construction. In some groundbreaking ceremonies, the shovel and the bulldozer mark the first day of construction. Meaning When used as an adjective, the term groundbreaking may mean being or making something that has never been done, seen, or made before; "stylistically innovative works". History Groundbreaking ceremonies have been celebrated for centuries in an attempt to begin the construction ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ecological Footprint
The ecological footprint is a method promoted by the Global Footprint Network to measure human demand on natural capital, i.e. the quantity of nature it takes to support people or an economy. It tracks this demand through an ecological accounting system. The accounts contrast the biologically productive area people use for their consumption to the biologically productive area available within a region or the world (biocapacity, the productive area that can regenerate what people demand from nature). In short, it is a measure of human impact on the environment. Footprint and biocapacity can be compared at the individual, regional, national or global scale. Both footprint and biocapacity change every year with number of people, per person consumption, efficiency of production, and productivity of ecosystems. At a global scale, footprint assessments show how big humanity's demand is compared to what Earth can renew. Global Footprint Network estimates that, as of 2014, humanity has ...
