MATLAB code for Modelling form roughness induced by tidal sand waves: second order perturbation approach analysis

This dataset contains the codes needed to compute the basic and second order flow obtained from a second order perturbation approach performed on a bed covered with tidal sand waves. The model setting is morphostatic and 2DV. The model is forced with an oscillatory flow, representative of the tidal flow.The flow is obtained by solving the dimensionless momentum and mass balance equations in Fourier space.本数据集包含用于计算基于二阶摄动法（second order perturbation approach）得到的基础流与二阶流的代码，该摄动方法应用于覆盖有潮汐沙波（tidal sand waves）的床面。模型采用静地貌（morphostatic）与二维垂向（2DV）设置，以表征潮流的振荡流作为模型强迫项。该流场通过在傅里叶空间（Fourier space）中求解无量纲化的动量与质量守恒方程得到。
