  • Modaomen estuary has been significantly changed by human activities and natural processes over the past decades. In order to study the evolution of the Modaomen Estuary during 1977-1988, a long-term (decadal-centennial scales) morphodynamic model which contains a rubble mound module and a waterway dredging mound module is developed to simulate the evolution of the Modaomen Estuary. The long-term simulation method and concept of model verification are discussed. Series of historical bathymetric charts are carefully analyzed to verify the model-simulated deposition and trends. The role of the human activities and natural process were separated based on the simulated result and situation analysis. The results of the numerical simulation and the morphodynamic analysis indicate that the sediment deposit of estuary on the west side is bigger than that on the east side, and affected by the riprap and reclamation project the main channel of Hengzhou is eroded by yearly, and the deep trough migrates seawards. However, the top of the Longshiku channel shows as severe deposition and channel continuously narrowing.
