Katrina Possisble Solutions

Possible Solutions to prevent another Hurricane Katrina ocean gates are another option that eat proven rattling affective in other areas of the world such as Holland, Britain, and Venice, which is likewise below sea level and has a large number of canals. sea gates are simply giant air-filled walls that cut hit water flow. These gates would most likely be placed on Lake Pontchartrains twain infinitesimal prohibitedlets and would be only be shut if a surprise was approaching.Such structures have been considered since the 1960s, but the idea was crushed in the late 1970s because people feared the gates would disrupt marine emotional state and sediment transportation. However this should not be an issue since the gates are unfastened the majority of the time. The main hurdle is cost, ranging from $500 million to 1 billion Closing or covering certain canals is an option that would service of process prevent storm surges from reaching so far midland. Currently canals and ta ke can give storm surge direct access to inland neighborhoods.The Mississippi River Gulf Outlet MRGO is one of the canals that has caused major problems in the past. Where MRGO meets the Intracoastal waterway there is a major area of funneling. The two fronts met at a narrowing point that forms the Industrial Canal and the water height is amplified 20-40%, set intense pressure on floodwalls causing them to burst. After Hurricane Katrina hit the narrow strip of wetlands between MRGO and Lake Borgne got even smaller, bringing to reality the fear that the two waters might merge into one.MRGO has less than five ships navigating its channel per solar day often times only one ship uses the outlet. MRGO has also amplified the wetland acquittance in the area, allowing salt water to intrude and kill off intrinsic vegetation. By keeping only heavily used channels open and turning the rest into trails or parks, flood damage could be reduced. Adding a subterranean drainage system to the ci ty is another idea that engineers have come up with. This would include turning some canals into culverts (covering them with trails and parks) and then having severe duty pumps (located on high ground) to pump the water fully out of the city.The culverts would help channel the water and get it out quickly in times of flood. This is a simple technology, but it is high-priced running around $1 million per mile of canal. Moving the pumping stations is a comparatively simple way to help prevent New Orleans from world overwhelmed. Installing heavy-duty pumping stations on high ground or in areas where they can act as damn-like buffers would allow water to be pumped out even when the city is overwhelmed.During Hurricane Katrina, once the pumping stations were make full the low areas just continued to rise in water level. Wetland refilling is another plan that could help protect New Orleans from storm surge. Wetlands act as natural barriers against wind-driven waters, but wetlands a re being ruined by saltwater intrusion everyday. Hand planting is very costly and time consuming, making it hard to implement. Source http//www. uwec. edu/jolhm/eh3/group7/futureneworleans. htm
