MATLAB code for Local characteristics of sand wave patterns are governed by underlying sand bank: A linear stability approach

This dataset contains the MATLAB codes needed to compute the basic state flow over a static sand bank topography as well as the perturbed modes containing flow patterns, sea surface elevation and topography following from a linear stability approach.The model is forced with an oscillatory depth-averaged flow, representative of the tidal flow over a sand bank.The solution is obtained by solving the Generalized Eigenvalue Problem posed by the dimensionless momentum, mass balance and Exner equations, and corresponding boundary conditions.
