I, as a dumb college student, went there and walked on the wing, the next week it collapsed.

It is the Auxiliary Structure (linked from your link) in the first picture and in the background is the failed low sill structure in 1973.https://www.wunderground.com/cat6/If-Old-River-Control-Structure-Fails-Catastrophe-Global-Impact Your link https://www.google.co.uk/search?q=failure+of+old+river+control+structure&tbm=isch&source=iu&ictx=1&fir=ftZcfe0bK17l7M%2CRRxDk-YnG3761M%2C_&vet=1&usg=AI4_-kTt_zi0s8YadwIFHcgXfndAvIoFOA&sa=X&ved=2ahUKEwjCiKyRmaLqAhVyVBUIHUVIDbgQ_h0wAHoECAUQBA&biw=1366&bih=646#imgrc=wdhLniFoa9rB9M There may be reverse flow if the river is low but there is little energy because the river is low. At high river low, flow thru the auxiliary structure is 10 times flow of Niagara falls My buddy said the eddy currents in the river travels the mile to the Aux structure and is undercutting the structure but as mentioned can't find the video. Did my buddy dream this or did the government delete all documents and videos as to not scare the public? Attached picture of the Low Sill before it failed.

Possible like other suggestions, the only hope is smart ones catch on. Remember this is reality not imagination. My so called imagination engineered two of the world's largest nuclear plants, derived a new method of calculation of Mississippi River hydraulics equations accepted by Tulane University top profesor who is paid by the CORPS to perform hydraulic studies for them, developed horizontal vessel with elliptical end caps volume equation when height is known (40 years ago and copyrighted) now all process studies use the equation, spent 40 years engineering safety critical systems for refineries and chemical plants, but I am only a hobbiest on this subject as most of the others. Everything I do is doubted by many but almost always comes to pass. I am a "f.....g Genus" according to a different Tulane professor, I thought that was funny.

Preliminary. 5 stars grading w/ a 1 star less safe than a 5 star for quick review then quantity of systems, then listing of systems with one sentence description. Link to the full description as already posted by CDC. Very little work for the hospital because everything is already defined, only a matter of Federal law requiring all hospitals fill the HSDS form.

I suspect a water flow lab can model an eddie but keeping the eddie in essentially a location would be a challenge. This is what happened when the old structure right wing fell in the 1973 flood. Roll down below 50% for the eddy which undercut the structure. America's Achilles' Heel: the Mississippi River's Old River Control Structure https://www.wunderground.com/cat6/Americas-Achilles-Heel-Mississippi-Rivers-Old-River-Control-Structure I call it an eddie but not sure, I am only an hobbyist on this subject.

I would think for the public to understand the Hospital air safety systems of hospital comparisons an HSDS is sufficient. Then one can quickly look at a large variety of hospitals in my area and make a comparison. Even a program sharing comparisons can be an good app. The MSDS is only an example and an HSDS can be similar in some ways. HSDS could have a grade for each hospital, Safety systems callouts, etc. and should be very simple for the public to understand.

Many of my friends fully understand MSDS sheets. Please review with some you know. Thanks for sharing.

Please review and comment. Louisiana marshes are destined to be washed away by Mississippi River Diversions. Talked to CPRA (Coastal Protection Restoration Authority) and they agree the marshes will wash away for 40 years because fertilizers from the river will feed marshes with plant having shorter roots and hurricanes will wash them away. Also talked to the CORPS and they do not know what will happen and asked me to share my concept with CPRA. Below pictures show different aspects of my concept and the Diversion Master Plan has thanked me for sharing the concept. Basically, the concept sends diversion waters to open waters west of the river when tides are decreasing and the diversion will stay in the waters and not flow into marshes. When tides are increasing diversion will be closed preventing diversion water from entering the marshes.

Supposedly the CORPS were using marine concrete and this will hopefully prevent undercutting the structure, kind of scary.

Called one of the largest hospitals in my area and they mentioned they could give me their maintenance crew and that would work but for the public a HSDS sheet on line would be easy to review. That way the public could easily compare different Hospitals.

Thanks for the guidelines and the CDC sent it to me earlier and I believe the next step needs to be done and they have not replied. Please see my latest reply to the CDC. >>>Thanks and now it is relatively simple for all hospitals to publish an HSDS for their property. Who or what organization can first provide a legal requirement for HSDS or research what a HSDS sheet will be composed of? Regards XXXXXXXXX

Thanks or the comment. There are eddies in the Mississippi River above the new control structure which flows to the Atchafalaya River and they travel upstream from the Mississippi about 1 mile to the structure. A friend said there was a video showing marine concrete was being pumped into the new structure, is undercutting happening with eddies at this structure location. I wonder about the eddies and if it's bottom would mostly stay closer to the structure if upstream concrete was sloped down to the structure. If so then there should be less undercutting. If the structure is undercut then the Mississippi River will divert to the Atchafalaya River. All videos, If did happen, are not found on the internet and may have been deleted. May need to give more please see link. https://www.google.com/search?q=old+river+control+structure&rlz=1C1CHBF_enUS867US867&oq=old+river+control+structure&aqs=chrome..69i57j0l7.8791j0j8&sourceid=chrome&ie=UTF-8

I believe a hospital document is needed to share disinfectant systems for air conditioners, filter systems for diseases and number of change outs of air per hour for the hospitals and each room. This document should be available on line and I call it HSDS (Hospital Safety Data Sheets) like MSDS (Material Safety Data sheets)

For an application with an eddy current not moving in an stream and the following condition exist. The stream bottom is concreted and at an angle, will the eddy's bottom move mostly downhill the concrete.

Thanks, Good to hear density may be good for this application. I suspect it will work within a few minutes but over a long time silt can become more dense than sand, this should not be a concern. One mentioned even level might not work because settling is not an interface but a collection of large diameter rocks, sand, light sand, heavy silt then lighter silt... If true then density may be best measurement. Even so, then heavy silt may hide in the sand and will drain out the bottom of the sediment tank. Not good for spreading silt out to the Louisiana marshes, will lose a certain percentage. Next I thought about a Hydrocyclone but variables such as pressure... affect its operation. Link. http://thermopedia.com/content/862/ Found an good test sonic meter but it cannot operate under pressure. Can get good graphs of collected particles and read sand and heavy silt levels independent. Even so, hiding silt would be a concern. Sonar Level System http://www.entechdesign.com/products/echosmart/ Summary: If Hydrocyclones can do almost a perfect silt/sand separation with control of pressure and flow ...etc., may have a perfect working system. I plan to propose a scaled down model and all measurements methods evaluated. The problem is within a few months The CORPS plan to release an environmental impact statement for public review but the head officer said if I can get academia CRPA (Coastal Restoration and Protection Authority) to review my concept then they can stop proceeding with diversions into the Mississippi River. What I may propose to CRPA. 1_10_short_Concept_and_review_of_zero_marsh_wash_away.docx

For a column of river sediment I want to measure fine sand / silt interface and perform analog control. So far I could not find a sensor to do this and resorted to density control for the moment. Density control (DT-1/DIC-1) SK-5A may work for recent tank collection? Any thoughts are greatly appreciated. Attached is a concept to collect sediment with dissolved fertilizer returning to the river and any thoughts on this concept is also appreciated.
