The closure of the reclamation project generally requires that the sluice has been built and can be normally opened and closed for drainage. There is a large amount of follow-up work after closured of this project. In order to reach the safe flood control standard for the next typhoon season after the closure, reduce the flood control risk, and strive for sufficient time for the subsequent construction of the seawall, it is necessary to closure in advance under the condition that the sluice has not yet been opened. Therefore, this project demonstrated the feasibility of the closure with cofferdam based on the premise of think outside the box and theoretical calculation. The successful completion and acceptance of the reclamation project proved that the project is successful.
