Re: Oil Rig explosion/Gulf Oil Spill Red, while you're right about course changes in the Mississippi river building new deltaic lobes, I still feel that natural sedimentation (that is being denied by the levees) actually will build up the existing lobes and replenish the marsh in the St Bernard and Lafourche lobes in particular. I also believe that constant dredging by 100 dredges in the Mississippi river channel and constantly depositing the spoil in those deltas will do what naturally occurred in 1,000 years in just 10 years. It's criminal that all those sediments are shunted into the deep blue sea instead of being redirected into the marsh. It's also criminal that the current dredging operations do nothing more than re suspend these sediments into the water column so that they will just go off the continental shelf. All in the name of saving money. It's cheaper to just channelize the river than to capture these valuable sediments and deposit them in areas of active erosion.
Re: Oil Rig explosion/Gulf Oil Spill The marshes near the river can be nourished with overbank deposits for sure, but they really won't be able to build delta lobes unless distributaries are allowed to develop and extend to spread that bedload around. The politicians will likely never allow that to happen north of Pointe a la Hache. Politics will keep the RIver from being partially diverted into its old Lafourche course and allowed to distribute sediment freely. It would impact all the Bayou communities way too much for them to consider it. A seriously researched proposal called The Third Delta plan would divert the river into conveyance channels through sparsely populated marshes east of Bayou Lafourche, split into two channels (one crossing through the Lafourche Ridge) and then allowed to naturally create distributaries and begin building new delta lobes in the Barataria and Terrebonne estuaries on either side of Bayou Lafourche.
Re: Oil Rig explosion/Gulf Oil Spill I like the third delta plan. How far do you think dredging operations could eventually pump sediment into say the Barataria bay system? As for politics ruling this process you're absolutely right. It's criminal that these sediments aren't considered a valuable resource and it's insane that politics rules over what is the right thing to do (like Nungesser's berm plan) ...so I guess the leadership of the nation (mainly congress) is criminally insane :lol:.

Re: Oil Rig explosion/Gulf Oil Spill By the way Okie, I heard that in the next "Top Kill" effort they're going to pump "Top" BP executives down there at the bottom of the Gulf...where there is no submerged oil !!:hihi:.
