Gumbya55... that's EXACTLY what many are lobbying for right now. Current beach replenishment methods are outdated, inefficient, and very short term solutions to very long term problems. Current research and informed experts are saying that effective shoreline protection requires a combination of sand replenishment and hard structures.
The damage is done... we've developed the coastline in areas where we shouldn't have. We can't go back. The challenge now is to engineer better methods of shoreline protection, and learn from our mistakes made in the past.
