A critic of Lousiana's attempts to build sand berms as oil spill barriers is saying, "I told you so."
Len Bahr, a former Louisiana State University marine sciences professor, posted images on his blog and sent msnbc.com a few more that he says shows how a new berm off the Chandeleur Islands is being washed away.
"These artificial sand ridges, planned in a science vacuum, will not survive the 2010 hurricane season," he predicted.
Lousiana Gov. Bobby Jindal had lobbied for, and got, federal permission to try the berms.
Bahr -- who also worked on coastal preservation projects for several state governors, including Jindal -- said the work might be motivated more by profits than science, calling "the aggressive selling of the project suspicious and suggests a hidden motive involving massive dredging contracts."
