Louisiana Has a "Duh!" Moment

Ok. Ok... I know that sounds sorta harsh, and I'm no geologist nor environmental engineer to have been strainin' my brain over this for how many years now..

Still, the last major story, which I read on New Orleans, discussed how so many of the problems facing the Sinking City were brought about by the process of dredging the Mississippi and dumping the sludge into the ocean. Reading this stroke of brilliance brought to mind what I imagine the inventor of the wheel must have felt like when finally putting that device to practical and deliberate use.

Better late than never, eh!

Louisiana Builds New Land with River Mud
By Peter Henderson

excerpt from Yahoo Reuters' . . .

A pilot project at the river mouth shows how the hurricane-ravaged state may be able to rebuild its vanishing coast with fertile river bottom soil now dumped by dredges into the ocean.

Louisiana continuously clears the bottom of the Mississippi River to aid navigation, then dumps far offshore sediment that the river carries from tributaries in more than 30 states.

But recently a dredge clearing a few miles of the river moved the mud into nearby shallow water, rather than dumping it off the continental shelf in the Gulf of Mexico.

The result: New terra, though not quite firma.

At the spot where the dredged sediment is being dumped, a roughly half-mile-square (1.3-square-km) patch of land has risen and a few wisps of green are struggling to take hold. The dredge has poured a combination of dark soil and river water through a pipeline to a monster version of a garden hose that releases the mess into the shallow brackish water.

Rebuilding such wetlands could help New Orleans absorb the blow of a future storm like Hurricane Katrina which devastated the city last year. Congress is considering bills that could pour a few billion dollars into coastal restoration in the state.

Louisiana's predicament is urgent. The state, which has 30 percent of the continental U.S. coastal marshes, is losing a football-field-sized piece of land to salt water every 38 minutes, according to the America's Wetland organization.

  1. there were scientists years ago saying that the wetlands should be rebuilt using just that technique- putting back the soil taken away by oil drilling. it worked in parts of louisiana and other portions of the gulf coast- just not enough time--or federal funding for a viable objective. guess all of the fed's expertise went into building levees.

  2. Dig it Betmo. At the end of the story, they talk about all the ideas which have been on proposed and studied and left behind; apparently because it's much less expensive to do studies than anything with what those find.

    Money siphons; even though the only bad news any of them found was that it takes money...

    Here's hopin' they finally figure out how WORTH it their region is.

  3. destroying iraq still seems to be more important to our gov't than preserving this country ...

  4. New wetlands! Outstanding! Now they just need to resist the urge to build on 'em.

  5. Well Rory, hopefully there're only two years more at most for this Admin. It'd be really nice if Congress had the integrity to make it much less. I still don't see that happening, though.

    As much as they dredge the mighty Miss, I'm hopin' there's enough new land for a li'l bit o' that inevitable activity as well, Kvatch.

    I think they may follow through on this and let Nature be the breakwall she was before the original wetlands "disappeared".

    Time (and money {sigh} ) will tell...
