Chavarrias Borras, V. (author), Ottevanger, W. (author), Labeur, R.J. (author), Blom, A. (author)The set of equations used in modelling river morphodynamics needs to be (at least) wellposed to be representative of the real natural phenomenon. As we deal with a time dependent process the solution needs to be wave-like to be well-posed. In other words, the solution must have a domain of dependence and of...abstract 2017

Chavarrias Borras, V. (author), Schielen, R.M.J. (author), Ottevanger, Willem (author), Blom, A. (author)A two-dimensional model describing river morphodynamic processes under mixed-size sediment conditions is analysed with respect to its well posedness. Well posedness guarantees the existence of a unique solution continuously depending on the problem data. When a model becomes ill posed, infinitesimal perturbations to a solution grow infinitely...journal article 2019
