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.
