了解中长期形态动力变化对海岸口可持续管理具有重要意义。本文分析了受多种环境因素影响的复杂河口入海口的形态动力学变化，提出了一个简化的物理模型来解释入海口中期形态动力学的历史变化。分析表明，河口入海口虽然经历了多尺度的形态变化，但在数年时间尺度上发生的变化更为显著和重要。简化的物理模型表明，这种简化的建模方法能够识别河口主要的历史形态动力学趋势。然而，入口水深数据集的长度和质量限制了模型的适用性和模型输出的质量。
Understanding medium to long term morphodynamic change is important for sustainable coastal and estuary management. This paper analyses morphodynamic change of a complex estuary inlet which is subjected to multiple environmental drivers and proposes a reduced physics model to explain the historic medium term morphodynamic change of the inlet. The analysis shows that even though the estuary inlet undergoes multiscale morphological change, the changes that take place over a timescale of several years are more significant and important. The reduced physics model suggests that this simplified modelling approach is able to recognise principal historic morphodynamic trends in the estuary. However, the length and quality of the inlet bathymetry data set limits the applicability of the models and the quality of model outputs.
