Are you interested in learning how to use the Delft3D Flexible Mesh model? Learn to apply these complex models to a real field case (West Bay, LA)? or learn the ins and outs of morphodynamics, sediment transport and water quality? 

The three day advanced training focusses on experienced modellers, Project engineers, project leaders and researchers. For new and less experienced users it is recommended to additionally follow the Delft3D 4: Getting started: Modelling Hydro- and morphodynamics course. 

During this advanced training you will  learn the ins and outs of the new Delft3D Flexible Mesh hydrodynamic model. The Delft3D Flexible Mesh Suite 2017 (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 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. 1D- and 2D grids can be combined, either connecting adjacent grids or a 1D grid overlying a 2D grid. Both Cartesian and spherical coordinate systems are supported. This facilitates tidal computations on the globe without imposing open boundary conditions. The grid generation tool RGFGRID includes new grid generation and orthogonalization algorithms for the construction of unstructured grids.



Some areas of applications

Tide and wind-driven flow;

Drying and flooding of inter-tidal flats;

Density gradients due to a non-uniform temperature and salinity concentration distribution (density driven flows);

Horizontal transport of matter on large and small scales;

Hydrodynamic impact of engineering works such as land reclamation, breakwaters, dikes;

Thermal recirculation of cooling water discharges from a power plant.



Objective of the course

This course consists of short lectures and extensive exercises. By the end day 1 you should be able to run a two-dimensional coastal hydrodynamic model using Delft3D Flexible Mesh Suite 2017. Day 2 focusses on a real life case study. Using the West Bay model we will learn you how to calibrate and validate the hydrodynamic model. By the end of day 2 you should be able to construct a model in Flexible Mesh that you can use in projects.

Day 3 provides additional lectures on advanced functionalities available in Delft3D 4 and Delft3D FM. This part of the course focusses on (1) running advanced morphodynamic models including the effects of graded sediments, multiple sediment classes, and morphodynamic acceleration techniques, and (2) water quality; how to use the DELWAQ to study water quality and ecology. 

DELWAQ is the engine of the D-Water Quality and D-Ecology programmes of the Delft3D suite. It is based on a rich library from which relevant substances and processes can be selected to quickly put water and sediment quality models together. The processes library covers many aspects of water quality and ecology, from basic tracers, dissolved oxygen, nutrients, organic matter, inorganic suspended matter, heavy metals, bacteria and organic micro-pollutants, to complex algae and macrophyte dynamics. High performance solvers enable the simulation of long periods, often required to capture the full cycles of the processes being modelled.
