Representative conditions of the long-term morphodynamic model

The long-term morphodynamic model is used to simulate morphologic evolution process in a long time scale,its key is to define the model representative input condition.Based on the research purpose,the sediment transport rate is compared under the repersentative condition and the natural input to confirm reasonable representative tide.According to the compute and the analysis,three representative tides with 12.5% more than mean tide range are selected for the typical conditions in the complex paleo-Pearl River estuary bays.
