Is Hydroseeding Enough?

Mike Werner, mayor of Gatlinburg, Tennessee, says that the city recently received grant funding to hydroseed areas in both the city and nearby national park that were burned by this winter’s fire. The fire was intense, and it’s hoped that hydroseeding will prevent landslides and mudslides.

Gatlinburg resident Erik Cooper owned a risk management and insurance business for more than two decades, and he isn’t sure that the root system from hydroseeding will be enough. Cooper hopes the hydroseeding contract will cover the tops of burned slopes, not just the bottom of the mountain and along the roads. “If everything above breaks loose and slides down, it’s going to erode the hydroseeded area below, and push it right into the road,” he said.

NASA Aids in Spill Survey

NASA teamed up with the US Geological Survey to show the continuing effects of the deepwater Horizon oil spill. By looking at data over the past few years, as well as the years before the spill, they were able to determine that the Barataria Bay shoreline is receding at more than 13 feet a year.

The spill, which coated the shoreline of Barataria Bay, occurred in 2010, and, in 2012, already aggressive erosion was worsened by Hurricane Isaac. Finally, though, researchers were able to get an erosion-rate baseline this year, since there were no major storm events.

“Being able to compare shoreline losses in a year without any major storm to losses both after the deepwater Horizon oil spill and after the hurricane was essential to correlating the erosion of the marsh to its underlying causes,” one researcher said.
