建立了近海营养后的三维形态动力学模型。在该模型中，建立了既考虑营养作用又考虑注入砂质营养作用的三维海滩演化模型。为了考虑泥沙的注入过程，模型采用了悬浮泥沙浓度的对流扩散方程计算。所提出的模型被应用到一个理想化的海滩与两个丁坝，以调查模型的性能，然后，该模型被应用到在荷兰的Egmond aan Zee进行的现场观测结果的滨面营养。最后，通过计算结果对模型的适用性进行了讨论。
A three-dimensional model of morphodynamics after offshore nourishment was developed. In the presented model, the 3D beach evolution model that is not only after nourishment but also taking into account the nourishment process of injected sand material. In order to consider the injected process of sand, the computation using the advection-diffusion equation for suspended sediment concentration was adapted in the model. The presented model was applied to an idealized beach with two groins in order to investigate the performance of the model, and then, the model was applied to a field observation result for shoreface nourishment carried out at the Egmond aan Zee in the Netherlands. Finally, the applicability of the presented model was discussed from the computed results.
