Course background

To simulate the evolution of random, short-crested windgenerated waves in coastal waters (which may include estuaries, tidal inlets, barrier islands with tidal ats, channels etc.) the wave module Delft3D-WAVE can be used. 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 sediment transport module of Delft3D-FLOW 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 behaviour 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 all interact through a well-defined common interface.

Some areas of applications are

The wave module can optionally be coupled with the other modules of Delft3D. In this way an efficient and direct coupling is obtained between e.g. the flow module (wave driven currents) and the sediment transport module (stirring 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 represented;
Estuarine areas including estuaries, tidal inlets and river deltas influenced by tidal currents, river discharges and density currents. Sediment can be non-cohesive (sand) or cohesive (silt). The areas may include tidal flats, channels and man-made structures, e.g. docks, jetties and land reclamations.
