According to an article from popular mechanics, the US Corps of Engineers is responsible for repairing and maintainging the erosion along the country’s coastlines. Apparently one of the common erosion control measures is pumping truckloads of additional sand & sediments to replace eroded shorelines.
It’s interesting to see a method like this used on such a large scale, knowing the strict erosion and sediment control restraints imposed on all other areas of civil engineering. Can the US corps not come up with a better solution than pumping foreign sediment to replace the old?
