Delft3D Basic courses

Deltares, Delft Hydraulics, has developed an integrated 3D modelling suite for coastal, river, lake and estuarine areas. It covers numerical modelling of flows, sediment transport, waves, water quality, morphological developments and ecology. The program, Delft3D, comes in several modules that are also subject of separate courses. The standard 2-day course covers Hydrodynamic modelling (Block 1). The standard course is followed by two optional parallel courses. The first option is a 3-day course that covers environmental modelling (Block 2a). The other 3-day option deals with modelling of wave propagation, sediment transport and bed dynamics (Block 2b).

Block 1 Hydrodynamic modelling in Delft3D:
18-19 March 2013, Deltares, Delft, the Netherlands
28-29 October 2013, Deltares, Delft, the Netherlands

Block 2a Environmental modelling in Delft3D:
20-22 March 2013, Deltares, Delft, the Netherlands
30 October - 1 November 2013, Deltares, Delft, the Netherlands

Block 2b Modelling of sediment transport and bed dynamics in Delft3D:
20-22 March 2013, Deltares, Delft, the Netherlands
30 October - 1 November 2013, Deltares, Delft, the Netherlands

We organize more software courses and meetings around these courses. More information about these software days is on the website www.delftsoftwaredays.nl.

Block 1: Hydrodynamic modelling in Delft3D

Course background

The hydrodynamic module Delft3D-FLOW is a multidimensional hydrodynamic simulation program that calculates non-steady flow and transport phenomena resulting from tidal and meteorological forcing on a curvilinear, boundary-fitted grid. In 3D simulations, the hydrodynamic module applies the so-called sigma co-ordinate transformation in the vertical, which results in a smooth representation of the bottom topography. It also results in a high computing efficiency because of the constant number of vertical layers over the whole computational domain.
The hydrodynamic module is based on the full Navier-Stokes equations with the shallow water approximation applied. The equations are solved with a highly accurate unconditionally stable solution procedure.

Some areas of applications are

• Simulation of drying and flooding of inter-tidal flats (moving boundaries);
• Turbulence model to account for the vertical turbulent viscosity and diffusivity based on the eddy viscosity concept;
• Density gradients due to a non-uniform temperature and salinity concentration distribution (density driven flows);
• Enhancement of the bottom stresses due to waves;
• Many options for boundary conditions, such as water level, velocity, discharge and weakly reflective conditions;
• Online visualization of model parameters enabling the production of animations.

• Introduction into grid generation;

Block 2a: Environmental modelling in Delft3D

Course background

Environmental modelling is based on the transport of substances in surface and ground water using the so-called advection-diffusion equation.
The water quality module Delft3D-WAQ is based on this equation and it offers different computational methods to solve it numerically on an arbitrary irregular shaped grid, on a grid of rectangles, triangles or curvilinear computational elements.
The sediment transport module Delft3D-SED can be applied to model the transport of cohesive and non-cohesive sediments, i.e. to study the spreading of dredged materials, to study sedimentation/erosion patterns and to carry out water quality and ecology studies where sediment is the dominant factor. It is in fact a sub-module of the water
quality module.
The ecology transport module Delft3D-ECO distributes the available resources (nutrients and light) in an optimal way among the different types of algae. It is in fact a sub-module of the water quality module. The particle tracking module Delft3D-PART is a three-dimensional mid-field water quality model. It estimates a dynamic concentration distribution by following the tracks of thousands of particles in time.

Water quality processes are described by linear or non-linear functions of selected state variables and model parameters.

Many process formulations are available in the form of a library, which smoothly interfaces with the water quality module. The library contains over 50 water quality process routines covering 140 standard substances.

Some areas of applications are

• Environmental Impact Assessment (EIA), objective evaluation of alternatives;
• Sewage and/or storm water outfall studies;
• Bio-availability of heavy metals (and organic micropollutants);
• Recirculation of cooling water from power and desalination plants including the release of bio-fouling chemicals such as chlorine;
• Effects of dredging on the environment;
• Simulation of oil spills with floating and dispersed oil fractions.

Objective of the course

Setting up and running a water quality, an ecological, particle tracking as well as an oil disposal simulation.

Course subjects

• Some basic theoretical concepts of environmental modelling;
• Some numerical aspect to transport modelling;
• Coupling hydrodynamic output to the environmental model input;
• Selecting substances and processes with the Processes Library Configuration Tool;

Block 2b: Modelling of sediment transport and bed dynamics in Delft3D

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 flats, 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 (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.

Objective of the course

Setting up and running a simple wave, wave-current, morphology and wave-current-morphology simulation.

Course subjects

• Introduction on wave prediction in coastal areas and wave models;
• SWAN wave module as used in Delft3D;
• Introduction on steering the different processes;
• Setting up and running wave simulation;
• Setting up and running wave-current interaction simulation;
• Setting up and running morphology simulation;
• Setting up and running wave-current-morphology
  simulation for coastal areas or rivers.
