Chavarrias Borras, V. (author), Stecca, G. (author), Blom, A. (author)In this paper we analyze the Hirano active layer model used in mixed sediment river morphodynamics concerning its ill-posedness. Ill-posedness causes the solution to be unstable to short-wave perturbations. This implies that the solution presents spurious oscillations, the amplitude of which depends on the domain discretization. Ill-posedness...journal article 2018

van Denderen, R. Pepijn (author), Schielen, R.M.J. (author), Blom, A. (author), Hulscher, Suzanne J.M.H. (author), Kleinhans, Maarten G. (author)Side channel construction is a common intervention applied to increase a river's conveyance capacity and to increase its ecological value. Past modelling efforts suggest two mechanisms affecting the morphodynamic change of a side channel: (1) a difference in channel slope between the side channel and the main channel and (2) bend flow just...journal article 2017
