The Disappearing Delta Before modern engineering of the chan-
nel, the Mississippi River carried over 400 million metric tons of sedi-
ment annually to its mouth. River deposits built from this sediment
now underlie most of coastal Louisiana. Today, the flow carries less
than half its previous sediment load. This decline, combined with
land subsidence and sea-level rise, means that the delta region is
shrinking in size each year.
The tremendous weight of sediment deposition at the Mississip-
pi’s mouth has caused the entire delta region to lower as sediments
become compacted, a process that is worsened by human activities
such as oil and gas extraction. In the past, additions of sediment bal-
anced this subsidence, allowing the delta to build. With the onset
of human activities such as upstream dam construction, the delta is
now subsiding without sediment replenishment.
Compounding the problem is the maze of excavated canals
through the delta for shipping and oil and gas exploration. As the
land surface sinks, these canals allow seawater to flow inland,
changing the salinity of inland waters. Freshwater wetlands whose
roots help stabilize the land surface during floods are now declining.
This makes the delta more vulnerable to flooding from hurricane
storm surge, another factor hastening the delta’s demise.
Finally, sea-level rise threatens coastal land and wetlands, most
of which are less than 1 m (3.2 ft) above sea level. With continued
local sea-level rise, lands not protected by levee embankments and
other structures that prevent flooding will con-
tinue to submerge.
In this chapter, we examine the natural pro-
cesses by which rivers erode, transport, and de-
posit sediment, forming landforms such as deltas.

Mississippi River in its present channel?
2. What three factors are causing the
Mississippi delta to disappear?

Mississippi River Delta
T
he immense Mississippi River basin
drains 41% of the continental United
States (Figure GN 14.1). From its head-
waters in Lake Itasca, Minnesota, the Missis-
sippi’s main stem flows southward, collecting
water and sediment over hundreds of miles.
As the river nears the Gulf of Mexico, the
flow energy diminishes and the river depos-
its its sediment load. This area of deposition
forms the delta, the low-lying plain at the
river’s end.
Like most rivers, the Mississippi continu-
ously changes its channel, seeking the short-
est and most efficient course to the ocean.
In southern Louisiana, the Mississippi’s chan-
nel has—over thousands of years—shifted
course across an area encompassing thou-
sands of square miles. Throughout this time

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

3. The Legend of Paul Bunyan Only the great outdoors was big enough to accommodate Paul, and it was natural that he should become the World's Greatest Lumberjack.In the year of the 'Blue Snow' when it was so cold the geese flew backward, Paul found a baby ox in the snow. It was so cold, the ox and snow was blue. After Paul took him home and warmed him, his color stayed blue. Paul named him Babe. Like Paul, Babe grew fast and soon was seven ax handles and a plug of tobacco wide between the eyes. For a between meals snack, Babe would eat thirty bales of hay, wire and all. It took six men with picaroons to pick the wire out of his teeth. Babe hauled the huge camp tank wagon which was used to pave the winter logging roads with ice. When it sprang a leak one day, it created Lake Itasca south of Bemidji and the overflow trickled down to New Orleans to form the Mississippi River.

31. Vanishing wetlands Over the past century, the nearly 1.3 million square mile watershed of the Mississippi River has experienced major environmental changes, including conversion of more than 80 percent of forested wetlands to agriculture and urban areas, channelization, dam construction, and river levees. The construction of massive structures that keep the river from switching channels has restricted sediment and freshwater supply to the flood plain.
32. Unintended consequences These changes have been especially damaging to the region's wetlands. The coastal wetlands associated with the Mississippi River delta make up nearly 40 percent of the total coastal salt marsh in the lower 48 states of the U.S. These wetlands are disappearing at an average rate of 25 square miles per year, about 50 acres each day. Fragile wetlands are readily damaged, directly and indirectly, by canals dredged for navigation and energy exploration.

34. Drilling for oil Over the last 100 years, Louisiana has lost over 400,000 hectares to open water. Prior to 1940, the majority of Louisiana's oil and gas fields were in freshwater. Subsidence, the rise in sea level, and loss of land have contributed to all but one oil field now being located in open saltwater. All of these fields are vulnerable to oil spills, particularly those directly offshore.
35. Technology pushes exploration Since the mid-1990s, the Gulf has experienced a resurgence, with computer-driven technological advances — and federal tax breaks on the royalties paid for drilling in leased government waters — opening new horizons in water as deep as 10,000 feet, hundreds of miles from shore. .
