Delft3D FM – Coastal Morphodynamic Modelling

This course focuses on estuarine, coastal and marine processes as well as the resulting morphological features and their morphodynamic behavior at various time scales.

The course starts with wave dynamics. To simulate the evolution of random, short-crested wind generated waves in coastal waters (which may include estuaries, tidal inlets, barrier islands with tidal flats, channels etc.) the new wave module D-Waves of the Delft3D FM Suite is designed. This wave module computes wave propagation, wave generation by wind, non-linear wave-wave interactions and dissipation, for a given bottom topography, wind field, water level and current field in waters of deep, intermediate and finite depth.

The second part of the course focuses on morphodynamic modelling. The D-Morphology module of the Delft3D FM Suite integrates the effects of waves, currents, sediment transport on morphological development, related to sediment sizes ranging from silt to gravel. It is designed to simulate the morphodynamic behavior of rivers, estuaries and coasts on time-scales of days to years. The typical problems to be studied using the morphological module involve complex interactions between waves, currents, sediment transport and bathymetry. To allow such interactions, the individual modules within Delft3D FM Suite all interact through a well-defined common interface.

In this course, presentations, hand-on case study and papers are used to develop skills in analyzing and solving morphodynamic problems.


Some areas of applications are

  • The D-Waves module can optionally be coupled with the other modules of the Delft3D FM Suite. In this way an efficient and direct coupling is obtained between e.g. the D-Flow FM module (wave driven currents) and the D-Morphology module (stirred by wave breaking);
  • Coastal areas including beaches, channels, sand bars, harbour moles, offshore breakwaters, groynes and other structures. The coastal areas may be intersected by tidal inlets or rivers, parts of it may be drying and flooding;
  • Rivers including bars, river bends (spiralflow effect), bifurcations, non-erodible layers, dredging operations and having arbitrary cross-sections (with overbankflow). Various structures may be included;
  • Estuaries including tidal inlets and river deltas influenced by tidal currents, river discharges and density currents due to sediment. Sediment can be non-cohesive (sand) or cohesive (silt). The areas may include drying and flooding, channels and man-made structures, e.g. docks, jetties and land reclamations.
