Beach nourishment is the latest chapter in a never-ending tale of erosion.

About 80 to 90 percent of sandy beaches along America's coastlines are eroding. This is a problem because the developments humans build near them are static. So as beaches shrink, coastal hazards can threaten to damage or destroy homes and businesses while negatively impacting tourism that depends on the beach.

The most popular strategy to counter these risks is a process called beach nourishment. Coastal engineers will add new sand to an eroding beach in order to rebuild or expand the shoreline.
Watch the video above to learn more about how beach nourishments can help defend the coast but are problematic as a long-term solution.

Beaches aren't the only area where economic disparities are hurting communities. Check out our video on how "levee wars" are making flooding worse: http://bit.ly/2ryAHcN

The excavators and bulldozers probably last like a year or 2 max because of the salt and sand.

Beach nourishment is sometimes a benefit from navigation channel restoration. Navigation channels are excavated to depths required and excavated material is often used in beach restoration.
This story is so flawed.
Yes beach nourishment and shoreline protection is expensive. But when done properly it can last for decades .
How do I know , I've done some of these projects. The problem today is almost no one wants to do these projects the right way because of the cost.
Now I'm some areas the the tide currents may shorten the life span of these projects. But, again , it's a matter of $$$ spent.

Due to rising sea levels situation, why not keep buildings at least 10 meters or 30 feet above sea level so they are not affected by rising sea levels. Then the beach can extend up to the ocean and RVs can get closer as they can simply drive away from the water.

or we could just go green

This could've helped a lot on the APES test

Nog a problem in Wales.

So basically all land will eventually become ocean?

You didn’t mention climate change...is this not a correlation also? Or do beaches naturally do this? I’m confused. Scientists say it’s climate change, but you just implied it’s natural...please explain.

I'm just saying that it took Lana Del Rey 13 beaches to find one empty

Beaches are dumb. Let the rich fall in the water. The sun gives everyone cancer so it's God's plan to rid us of dumb deadly beaches.

Correction: The correct spelling of “warning” in Persian is هشدار.

Chances are you wouldn’t be able to recognize a biohazard even if you were looking right at one. But the biohazard symbol? It’s pretty easy to spot. Most warning icons rely on previously established objects or symbols: a general caution might use an exclamation point, and a fire warning might use an illustration of a flame. But the biohazard symbol references an idea that is much harder to picture — and in the 50 years since its invention, it has become one of the most recognizable icons on the planet. But can the meaning of a symbol like this last an eternity? A special Department of Energy project is trying to figure that out.
