Agelbert NOTE: THe Mississippi water level you sea below on the Carrollton Gage is about 4 FEET ABOVE where it normally is when a Hurricane hits New Orleans. You see, hurricanes normally hit later in the year (late August to September) when the Mississippi is not flooding. When river flooding meets a hurricane or tropical storm, as it is about to do NOW (thanks to Catastrophic Climate Change), the levees may breach and, once again, New Orleans will flood massively.

The Army so-called "Corps of Engineers" (a military + corporate = fascist organization from the word go) will NEVER properly address Catastrophic Climate Change. Don't count on their multi-billion dollar "anti-flood" infrastructure boondoggles (that we-the-people, instead of the 🦖 Hydrocarbon Hellspawn polluters causing this climate mayhem, are ALWAYS forced to pay for) to stop the destruction. They just see "business opportunities" in climate disasters.



New Orleans’ Achilles Heel: A Hurricane Storm Surge During a Mississippi River Flood?

Dr. Jeff Masters  ·  July 10, 2019, 5:28 PM EDT

SNIPPET:

Figure 5. Water level at the Carrollton gage on the Mississippi River at New Orleans during the passage of Hurricane Isaac in August 2012. Prior to Isaac's arrival the river was running just two feet above its record low. Isaac drove a storm surge of ten feet to New Orleans. Levees on the Mississippi protect New Orleans to a stage height of 20 feet above sea level, so Isaac's storm surge was nine feet below the tops of the levees. Image credit: NOAA Tides and Currents.

Armoring the levees

I've been reviewing the vulnerability of New Orleans in the wake of the $14.6 billion upgrade to the levee system since Katrina. One interesting feature is the "armoring" of the levees that has occurred--fabric mats that grass can grow through have been installed along the inside of key stretches of the levee system, which should greatly reduce or eliminate the chances of overtopping causing a levee breach. The Army Corps states that the armoring will mean that the city will just flood to a depth of 5' in an overtopping situation, greatly reducing damages. That’s much lower than the 15 to 20 feet of inundation in the lowest locations in the New Orleans from the multiple levee breaches and floodwall failures that occurred during Hurricane Katrina.

Unfortunately, this armoring project is not yet complete, and the inside portions of the levees along the Mississippi River protecting New Orleans have not received armoring. This means that if the storm surge from a hurricane moves up the Mississippi River and overtops the levees, there is the potential that water flowing over them could scour their base and undermine the structure, causing a breach--a serious situation that could lead to life-threatening inundations like Hurricane Katrina wrought.
