Take a boat ride along the Atlantic Intracoastal Waterway in Georgia’s Chatham County and it won’t take long to see that parts of its marshy banks are wearing away at an unnatural pace.
Instead of marsh grass at the water’s edge, steep scarps expose tree roots.
“The northern portion of the Intracoastal from Savannah to Doboy Sound is really dominated by erosion,” said Clark Alexander, a Skidaway Institute researcher who has spent two years studying changes in the waterway.
While you’re on that boat ride you won’t have to look far for the source this erosion. You’ll be producing it with a wake.
