When a major hurricane strikes, it can be devastating for an island nation’s coastlines, and when a storm of hurricanes hits, it’s even more devastating.
So in the months after Hurricane Katrina, the U.S. Coast Guard took it upon itself to assess the state of the coast.
The Coast Guard’s mission in the Gulf of Mexico is to monitor storms and assess their impacts, and for the first two years of Katrina, there was nothing to see.
But in September of 2007, the storm came roaring ashore, leaving behind a trail of destruction, leaving coastal communities to rebuild, and then, eventually, rebuild.
In the aftermath of Katrina and Hurricane Andrew, a storm surge was predicted to hit New Orleans and Louisiana, bringing about the greatest flooding in the country’s history.
While many of those communities struggled, the Coast Guard and other agencies like NOAA and the Army Corps of Engineers worked to help rebuild.
The agencies used their expertise to create a comprehensive marine engineering assessment, which included a number of projects in the United States.
The result is a comprehensive assessment of the U-shaped design of the Mississippi River Basin, which includes the Mississippi, Alabama, Arkansas, and Florida.
NOAA was tasked with identifying and modeling the design issues, which NOAA describes as “critical design and engineering issues that could cause the levee system to fail.”
NOAA also created a simulation of the storm that could help them assess its impact.
This year, the Corps of Engineering began a study of the design of two major Mississippi River levees in Alabama.
They will be the first to test the design with the floodwaters from Katrina, as well as the impact of the new flooding on the Mississippi itself.
Here are some of the key findings from the report, which is available online.
The Gulf of Louisiana is a system of high-water dams that connect Mississippi and the Gulf, and this study is focused on how these dams would affect the Gulf’s flooding.
The most significant design feature of the Gulf levees is that they are built on bedrock that is highly porous.
As the water flows over the porous material, the flow slows and the volume increases, which in turn causes the levees to move downstream more slowly, which reduces the volume of water in the river.
This slows down the river, which leads to higher levels of sediment and makes it harder for storm surge to build up and eventually, cause flooding.
When the Mississippi is breached, the sediment and rocks that formed when the river flowed over the floodplain become trapped by the high water, which means that they must be pulled up to the surface to be carried downstream by the river’s current.
This means that the lower sections of the leveeces are also vulnerable to flooding.
To better understand the effects of a levee failure, NOAA’s study was able to model what would happen if the Mississippi was breached in an earthquake.
To simulate this scenario, they used the model’s flood model to simulate the impact on the leveen system.
The model simulated the impact from an earthquake, and the resulting model was used to determine how many homes would be lost and how much damage was done to homes.
The study also determined that there were two major design features that could impact the river levees.
The first is a low-pressure system, which sits underneath the Mississippi and allows water to flow more slowly through it.
The low-velocity flow also makes it more difficult for the river to fill up, which would increase the likelihood of flooding.
However, the study did not consider the effects that could occur in an extreme earthquake, which has the potential to destroy a dam.
In order to create the best model possible, NOAA developed a model that incorporates the effects from an extreme seismic event, and they used this model to test two of the most critical design features of the system, the leveepower and flood protection systems.
This is the first time that a study has focused on the impact that these two design features could have on the Gulf and the Mississippi river systems.
The second design feature is the water entry and exit points, which are where the floodwater can enter and exit the leveefault.
The design features can be identified by the shape of the river or by the presence of sediment.
The two most significant impacts of a water entry or exit point are the potential for the flood to enter the leveevault, and its potential to damage or kill a structure.
This study also addressed the effects on the river and levee systems from the impact a storm would have on a flood.
The U-shape of the drainage system of the Atlantic Seaway and the Pacific Ocean are critical to how water is distributed throughout the basin, and it is important to understand how they are influenced by storm surge.
The research was based on data from the UHF network, which collects data from weather stations across the United Kingdom and provides information on storm surges, wind speed, and wind direction. NOAA has
