Getting started with Delft3D 4 and Delft3D FM – North American Deltares Software Days 2019, Baton Rouge

Interested in Delft3D hydromorphodynamic and morphodynamic modleling? This 3-day course will get you started using the Delft3D Model structured (Delft3D 4) or unstructured (Delft3D FM) model suite.

Delft3D 4 has been designed to simulate the complex interactions between waves, currents, sediment transport and bathymetry over time-scales of days to decades. This allows you use Delft3D for a wide variety of morphodynamic modeling studies such as: Coastal areas including beaches, channels, sand bars, harbour moles, offshore breakwaters, groynes and other structures.

The Delft3D Flexible Mesh Suite (Delft3D FM) is the successor of the structured Delft3D 4 Suite. The Delft3D FM Suite can simulate storm surges, typhoons / hurricanes, tsunamis, detailed flows and water levels, waves, sediment transport and morphology, water quality and ecology and is capable of handling the interactions between these processes. The key component of Delft3D FM is the D-Flow Flexible Mesh (D-Flow FM) engine for hydrodynamic simulations on unstructured and structured grids in 1D-2D-3D. D-Flow FM is the successor of Delft3D-FLOW and in the near future SOBEK-1DFLOW.

Like Delft3D-FLOW, D-Flow FM is capable of handling curvilinear grids, that provide very good performance in terms of computational speed and accuracy. Further to that, the grid may now also consist of triangles, quads, pentagons and hexagons. This provides optimal modelling flexibility and ease in setting up new model grids or modifying existing ones, or locally increasing resolution. Both Cartesian and spherical coordinate systems are supported. The grid generation tool RGFGRID includes new grid generation and orthogonalization algorithms for the construction of unstructured grids.

Course subjects

Through a combination of lectures and hands-on exercises, our Delft3D Coastal Hydrodynamic Modelling course introduces:

  • grid generation for structured and flexible grids
  • unique bathymetry interpolation methods
  • quickly setting up and running two-dimensional (2D) coastal – estuarine models and analyzing results using the Delft3D FM build-in post-processing tools and third-party tools.

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.) Delft3D 4 and Delft3D FM. 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 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.

In this course we will set up and run (1) 2d hydrodynamic model, (2) standalone wave, (2) wave-current, (3) morphology and (4) wave-current-morphology simulation.

This course is aimed at
