Faculty Civil Engineering and Geosciences Department Hydraulic Engineering Date 2014-06-15 Abstract A hampering factor in the application of morphodynamic models is the potential excessive time needed to complete a simulation. One way to upscale a model run is the use of a morphological factor, or MORFAC. In this paper, we investigate the upper limit to the value of the MORFAC as a function of model geometry and timestep for a schematized case of tidal flow, and we suggest a way to make a conservative estimate of this value using a morphology-based CFL condition.
