Bonnet Carré Crevasse
The Bonnet Carré Crevasse (1871) was one of several levee breaches in the Bonnet Carré area in the mid-to-late 19th century. Bonnet Carré was approximately from New Orleans, Louisiana. The breach occurred when excess water from the Mississippi River flowed over the east bank levee of Bonnet Carré. The original levee was over high, and the Crevasse itself spanned about . Local drainage systems were unable to contain the floodwater. The water rushed at 8 miles per hour, causing the width of the breach to increase by the day. Strong northerly winds caused the excess water entering Lake Pontchartrain to flow into populated areas to the east, including neighborhoods Metairie and Gentilly. The increasing force of the flood also caused another nearby levee to break. Although the devastation to the Bonnet Carré area was great, its ecological impacts were somewhat beneficial. By diverting river water and sediment, the crevasse saved a greater portion of land surrounding the ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Crevasse
A crevasse is a deep crack that forms in a glacier or ice sheet. Crevasses form as a result of the movement and resulting stress associated with the shear stress generated when two semi-rigid pieces above a plastic substrate have different rates of movement. The resulting intensity of the shear stress causes a breakage along the faces. Description Crevasses often have vertical or near-vertical walls, which can then melt and create seracs, arches, and other ice formations. These walls sometimes expose layers that represent the glacier's stratigraphy. Crevasse size often depends upon the amount of liquid water present in the glacier. A crevasse may be as deep as and as wide as The presence of water in a crevasse can significantly increase its penetration. Water-filled crevasses may reach the bottom of glaciers or ice sheets and provide a direct hydrologic connection between the surface, where significant summer melting occurs, and the bed of the glacier, where additional wa ...

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 ...

Bonnet Carré Spillway
The Bonnet Carré Spillway is a Flood#Flood defences, planning, and management, flood control operation in the Lower Mississippi River, Mississippi Valley. Located in St. Charles Parish, Louisiana, about west of New Orleans, it allows floodwaters from the Mississippi River to flow into Lake Pontchartrain and thence into the Gulf of Mexico. The spillway was constructed between 1929 and 1931, following the Great Mississippi Flood of 1927, and has been designated as a National Historic Civil Engineering Landmark by the American Society of Civil Engineers. History The Bonnet Carré Crevasse was one of several levee breaches in the Bonnet Carré area in 1871. Local drainage systems were unable to contain the floodwater and strong winds caused the water to enter Lake Pontchartrain and surrounding urban areas. The river levee was not restored until 1883. The spillway was built in response to the Great Mississippi Flood of 1927 that inundated much of the Mississippi River basin. It wa ...

Floods In Louisiana
A flood is an overflow of water (list of non-water floods, 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. Environmental issues, 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 Wetland conservation, 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 Effects of climate change on the water cycle, intensification of the water cycle and sea level rise. For example, climate change makes Extreme weather, extreme weather events more frequent and stronger. This leads to more intense floods and increased flood risk. Natural types of floods include riv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
