5、xactly how to rebuild the city and its defenses to avoid a repeat catastrophe is an open question.Plans fbrimproving its levees and restoring the barrier of wetlands around New O rleans have been on the table since 1998,but federal dollars needed to implement them never arrived.After the tragedy,tha

6、ts bound to change,says JohnDay,an ecologist at Louisiana State University(LSU)in Baton Rouge.And if there is an upside to the disaster,hesays,ifs that now weve got a clean slate to start from.nMany are looking fbr guidance to the Netherlands,a country that,just like bowl-shaped New O rleans,sitsmos

7、tly below sea level,keeping the water at bay with a construction of amazing scale and complexity.O thers,pointing to Venices long-standing adaptations,say its best to let water flow through the city,depositing sedimentto offset geologic subsidence-a model that would require a radical rethinking of a

8、rchitecture.Another idea is tolet nature help by restoring the wetland buffers between sea and city.But before the options can be weighed,several unknowns will have to be addressed.O ne is precisely how thecurrent defenses failed.To answer that,LSU coastal scientists Paul Kemp and Hassan Mashriqui a

9、re picking theirway through the destroyed city and surrounding region,reconstructing the size of water surges by measuringtelltale marks left on the sides of buildings and highway structures.They are feeding these data into a simulation ofthe wind and water around New O rleans during its ordeal.We c

10、an*t say fbr sure until this job is done,says Day,but the emerging picture is exactly what wevepredicted fbr years.*Namely,several canalsincluding the MRGO,which was built to speed shipping in the1960shave the combined effect of funneling surges from the Gulf of Mexico right to the citys eastern lev

11、ees andthe lake system to the north.Those surges are to blame fbr the flooding.nO ne of the first things well see done isthe complete backfilling of the MRGO canal,predicts Day,which could take a couple of years.”The levees,which have been provisionally repaired,will be shored up ftirther in the mon

12、ths to come,althoughtheir long-term fate is unclear.Better levees would probably have prevented most of the flooding in the city center.To provide further protection,a mobile dam system,much like a storm surge barrier in the Netherlands,could beused to close off the mouth of Lake Pontchartrain.But m

13、ost experts agree that these are short-tenn fixes.The basic problem fbr New O rleans and the Louisiana coastline is that the entire Mississippi River delta issubsiding and eroding,plunging the city deeper below sea level and removing a thick cushion of wetlands thatonce buffered the coastline from w

14、ind and waves.Part of the subsidence is geologic and unavoidable,but the reststems from the levees that have hemmed in the Mississippi all the way to its mouth fbr nearly a century to preventfloods and facilitate shipping.As a result,river sediment is no longer spread across the delta but dumped int

15、o theGulf of Mexico.Without a constant stream of fresh sediment,the barrier islands and marshes are disappearingrapidly,with a quarter,roughly the size of Rhode Island,already gone.After years of political wrangling,a broad group pulled together by the Louisiana government in 1998proposed a massive$

16、14 billion plan to save the Louisiana coasts,called Coast 2050(now modified into a plancalled the Louisiana Coastal Area project).Wetland restoration was a key component.Its one of the best andcheapest hurricane defenses,says Day,who chaired its scientific advisory committee.Although the plan was ne

17、ver given more than token funding,a team led by Day has been conducting a pilotstudy since 2000,diverting part of the Mississippi into the wetlands downstream of the city.The results are asgood as we could have hoped,he says,with land levels rising at about 1 centimeter per year-enough to offsetrisi

18、ng sea levels,says Day.Even if the wetlands were restored and new levees were built,the combination of geologic subsidence and risingsea levels will likely sink New O rleans another meter by 2100.The problem might be solved by another ambitiousplan,says Roel Boumans,a coastal scientist at the Univer

19、sity of Vermont in Burlington who did his ph.D.at LSU:shoring up the lowest land with a slurry of sediment piped in from the river.The majority of the buildings in theflooded areas will have to be razed anyway,he says,“so why not take this opportunity to fix the root of theproblem?*The river could d

20、eposit enough sediment to raise the bottom of the New O rleans bowl to sea level in50 to 60 years,M he estimates.In the meantime,people could live in these areas Venice-style,with buildings builton stilts.Boumans even takes it a step Rirther:You would have to raise everything about 30 centimeters on

22、rotect the city in the future will be tied to how many people will live there,and where.nthere may be a largecontingent of residents and businesses who choose not to return,says Bill Good,an environmental scientist atLSU and manager of the Louisiana Geological Surveys Coastal Processes section.It is

23、 also not yet clear howdecisions about the reconstruction will be made,says Good,HSince there is no precedent of comparablemagnitude.Every level of government is sure to be involved,and“the process is likely to be ad hoc.Even with the inevitable mingling of science and politics,we still have a uniqu

24、e chance to back out of somebad decisions,says Good,who grew up in New O rleans.I hope that we dont let this once-in-history opportunityslip through our fingers in the rush to rebuild the city:1.The passage gives a general description of the suggestions to reconstruct New O rleans after HurricaneKat
