Our transcription: If there is technology and engineering available for transporting sand around dams, why isn't this being done?
One reason may be that many scientists originally rejected the idea that dams actually contribute to erosion, but that is no longer the case.
The problem currently seems to be that the value of sand as a coastal resource may still not be fully recognized.
A lot of the sand is already excavated by sand and gravel companies for construction material.
It should be treated as a public resource and a fair market value paid for it.
For instance, people on the beach would be willing to pay many dollars per cubic yard for "nourishment sands" -- sands that sand and gravel companies haul away at just a fraction of a dollar a cubic yard.
So this needs, I think, to be regulated just like water and treating sand as a public resource.
