Morphodynamic modeling and morphological upscaling in a fine sediment system

Sediment mobility and memory effects distinguish transport and morphodynamics in fine sediment settings from sandy settings. This paper focuses on the morphodynamic modeling of fine sediment systems, and an adaptation of modeling procedures more commonly used in sand-dominated systems. An extensive dataset of short-term transport and...

Transport and Morphodynamics in a Fine Sediment Estuary: From Conceptual Understanding to Numerical Modeling

This dissertation presents a study of fine sediment transport and morphodynamics in estuarine settings using data from the Lower Passaic River (LPR), located in New Jersey, USA. Originally a relatively shallow system, it has been dredged and deepened for navigation purposes from the late-1800s onwards, along with other modifications such as...

Morphodynamic Upscaling with the MORFAC Approach in Tidal Conditions: The Critical MORFAC

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...

Morphodynamic upscaling with the MORFAC approach

The Morphological Acceleration Factor (MORFAC) approach for morphodynamic upscaling enables the simulation of long term coastal evolution. However the general validity of the MORFAC concept for coastal applications has not yet been comprehensively investigated. Furthermore, a robust and objective method for the a priori determination of the...
