Along with Climate Change, the Rising of Sea Level, the Enhancement of Storm Surge, the Increasing of Extreme Waves, the Revetment and the Land Area Behind It Are Facing More and More Risk. under the Action of Strong Typhoon, Some Revetments Were Damaged. in the Process of Restoration, Revetment Elevation Shouldn't Increase Due to the Limitation of Land Area Which Already Built, How to Achieve the Protection Effect under the Condition of Wave Enhancement in a Limited Height Has Become the Problem and It is Researched in This Paper. Overtopping is the Main Form of Damage to Revetment and Land Area Caused by Strong Waves. by Building Green Buffer Zone, the Water Flow Speed of Overtopping Water Body Can Be Reduced, and the Drainage Time of Strong Waves Can Be Prolonged, So as to Reduce Overtopping. Combined with the Actual Project, the Green Buffer Zone is Simulated by Physical Model Test of Cross Section, and Compared with the Traditional Revetment without Green Buffer Zone, the Results Show That Its Efficiency is Obvious.
