Advances in computational morphodynamics using the International River Interface Cooperative (iRIC) software

Abstract: Results from computational morphodynamics modeling of coupled flow-bed-sediment systems are described for 10 applications as a review of recent advances in the field. Each of these applications is drawn from solvers included in the publicdomain International River Interface Cooperative (iRIC) software package. For mesoscale river features such as bars, predictions of alternate and higher mode river bars are shown for flows with equilibrium sediment supply and for a single case of oversupplied sediment. For mic… Show more

“…Herein, we use a two-dimensional morphodynamic model, Nays2DH [20], which is a plane two-dimensional morphodynamic model incorporated in the international River Interface Coorperative (iRIC) software package [21,22] to reproduce the various types of large-scale bedforms including alternate bars and multiple bars (braided channel). This is an unsteady shallow water flow model with a Manning-Strickler type roughness model for the flow field, and an equilibrium-bedload transport model for sediment transport and morphodynamics.…”

“…For instance, 3D bedforms cause secondary flow circulations (Maddux et al, 2003a,b), and the level of turbulence increases or decreases depending on the shape of the crests of 3D dunes (Venditti, 2007). Based on these experimental studies, the motion of 3D dunes has been computationally modelled by coupling large eddy simulation (LES) and the sediment continuity equation (Nabi et al, 2013;Khosronejad et al, 2015;Shimizu et al, 2019).…”
