Yes, what you say is true for many situations. This is a different situation. My study is a near perfect study based on actual river velocities and power. My conclusions are almost guaranteed to happen if LA Speaks carry out their plan without taking into account river dynamics. I have discussed this with the Master Plan restoration engineers and I believe they did not consider river dynamics when they came up with their various diversions models. The CORPS has written me and they will model the Master Plan diversions and see what effect the diversions will have on river dynamics. The reason for me posting is to make the public and the scientific community aware of the grave consequences of the Master Plan. Hopefully others will write their elected officials or the CORPS supporting a plan that minimizes changes in river dynamics. I live at the worst peak meander point of the river. My Dad's house was in the middle of where the river is now. The Corps has moved the house to prevent it from falling into the river and now the river has a whirlpool the size of a football field 500 feet downstream of the original peak meander point. Increasing the river velocity will almost guarantee another undermining of this peak meander point and if the river is at high stage a tidal wave of massive proportions will drown southeast Louisiana. The distruction will make Katrina distruction pocket change compared to the tidal wave. Below are two recommendations to minimize changing river dynamics I have proposed to my elected officials, the Master Plan engineers, and the Corps. Hopefully one recommendation is used with the Master Plan. http://members.cox.net/wetlandsrst/A%20shipping%20terminal%20has%20fallen%20in%20the%20river%20in%20the%20past.doc ...The Mississippi River Master Plan diversions will only work if: ·All future diversions are close to the mouth of the Mississippi River. ·Or the total flow of the bird foot delta area is decreased by the added upstream diversion flows. ... Thanks again for reviewing. Ken

ABSOULTY NOT I have posted a scientific based article not a soapbox. Do you have scientific knowledge about the subject? I am a degreed engineer and my calculations are fully scientific and mathematic based. If you do not understand I will be glad to explain any question you may have. Thanks for reviewing but More knowledge may be needed for your informed input. Ken Note: In another forum I have received input from a geologist and he agrees in general with my assessment. Also Richard Wagneer of the Corps in New Orleans has written me and stated the Corps will address this concern when they address the LA Speaks Master Plan. Would you like to see the letter? Paralith has asked a question and I tried to share another way of understanding the scientific based conclusion agreed with by a Geologist and head of river forums. Please do review the post which is an inviting discussion. No one else has posted and I am only posting more details for many to read. Definition of Bashing. Please share where bashing applies to me.

LA Speaks Draft Master Plan will not work because a river environmental disaster will occur with the plan as proposed A shipping terminal has fallen in the river in the past (1974-75? near Plaquemine, La.) from high velocity water but I am sure the terminal was designed to meet government regulations with respect to piling depth...etc. After this event several diversions were added to the river and this has added piling undercutting capability to the river due to added velocity. Adding more diversions in the future may be the straw that breaks the back and, I believe, more shipping terminals will fall into the river. There should not be any added diversions that increases river velocities except for diversions close to the mouth of the river. Diversions close to the mouth of the river essentially do not increase river velocities and do not decrease the resistance of the river. But any diversions above the mouth of the river decrease the resistance of the river by creating a parallel run with the river. This parallel run starts at the point of the river diversion and continues downstream to the Gulf. These added diversions will decrease the downstream resistance and river velocity north of the diversion will be higher than before the diversions are added. "A combination for shipping terminals to fall into the river" I believe there is nothing that can be done to stop the added erosion power of the river from undermining shipping pilings. Also I believe, grading, armoring the river bank with stone, and installing concrete matt on the river bank will not stop the erosive power of the river, from higher velocities, undermining the levee at peak meander points. And this undermining of the levee will send a destructive tidal wave into Southeast Louisiana. The Mississippi River Master Plan diversions will only work if: • All future diversions are close to the mouth of the Mississippi River. • Or the total flow of the bird foot delta area is decreased by the added upstream diversion flows. A magnitude example of possible diversions The Third Delta Conveyance Channel may well destroy Southeast Louisiana because the levee above Donaldsonville, Louisiana will be undermined. Higher river velocities above Donaldsonville will be generated by the Conveyance Channel flow because the flow will decrease the river resistance below Donaldsonville. These higher velocities will undermine peak meander points of the river above Donaldsonville and in turn the levee will be undermined and collapse sending a tidal wave south. Please see below article that shows stream channelization increase flow velocity. I believe one can safely conclude: • Stream channelization reduces the resistance of a stream and this is why the stream has faster velocities. • For the Mississippi River, approximate 1/3 of the river diverted by the Third Delta Conveyance channel will reduce the resistance of the river and as a result the velocity and the erosive power of the river upstream of the diversion will increase. *********************************** …Because overall stream behavior is maintained in dynamic equilibrium, changes in one of several variables such as flow, velocity, or streambed substrate will result in compensating changes in the other variables. Channelization and armoring (rip-rapping) of a stream section will cause permanent changes, removing the dynamic nature of not only the altered section, but also affecting the adjoining stream sections further downstream than might initially be anticipated. Stream channelization often increases stream velocity, thereby increasing the erosive power of the stream. Durable protection or armoring is then required to ensure the stability of the engineered modification through all flow events…. http://www.fws.gov/midwest/KalamazooNRDA/documents/IChap_8.pdf Page 5 ******************************** Wetlands restoration will produce an unstable Mississippi River? http://www.freewebs.com/wetlandsmiss/index.htm
