'Katrina Possisble Solutions\r'

'Possible Solutions to prevent a nonher(prenominal) Hurri scum bage Katrina Sea gates are another(prenominal) pickax that have proven very affective in other areas of the world such as Holland, Britain, and Venice, which is besides below sea level and has a immense number of canals. Sea gates are precisely giant air-filled walls that cut off piss flow. These gates would most likely be determined on Lake Pontchartrain’s two limit outlets and would be only be closed if a violent charge was approaching.Such structures have been considered since the 1960’s, simply the idea was crushed in the late 1970’s because people feared the gates would cut off marine life and sediment transportation. However this should not be an issue since the gates are well-defined the majority of the time. The main hurdle is cost, ranging from $500 cardinal to 1 billion Closing or screening certain canals is an option that would help prevent storm surges from reaching so far in land. Currently canals and crease can give storm surge pose access to inland neighborhoods.The Mississippi River Gulf number [MRGO] is one of the canals that has caused major problems in the past. Where MRGO meets the Intracoastal Waterway on that point is a major area of funneling. The two fronts met at a narrowing point that forms the Industrial furnish and the water height is amplified 20-40%, putting intense compress 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 honesty the fear that the two waters might blend in into one.MRGO has less than five ships navigating its channel per day; ofttimes times only one ship uses the outlet. MRGO has likewise amplified the wetland loss in the area, allowing salt water to intrude and kill off native vegetation. By holding only heavily used channels apply and turning the rest into trails or parks, flood toll could be reduced. Adding a subterranean drainage system of rules to the city is another idea that engineers have line up up with. This would include turning some canals into culverts (covering them with trails and parks) and hence having heavy duty kernels (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 simpleton technology, but it is dearly-won running about $1 million per greyback of canal. Moving the pumping stations is a relatively simple way to help prevent New siege of siege of Orleans from being 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, one time the pumping stations were flooded the low areas just proceed to rise in water level. Wetland rehabilitation is another plan that could help protect New Orleans from storm surge. Wetlands act as natural barriers against wind-driven waters, but wetlands are being destroyed by brine intrusion everyday. Hand planting is very expensive and time consuming, making it hard to implement. Source: http://www. uwec. edu/jolhm/eh3/group7/futureneworleans. htm\r\n'
