Delft3D Flexible Mesh – River modelling

Wednesday – Thursday, 26-27 October 2016

This river modelling course is intended for Delft3D Flexible Mesh (Delft3D FM), Delft3D 4 and SOBEK 2 users. Delft3D FM is the next generation simulation software package for evaluating and forecasting hydraulic functioning of rivers under normal, extreme and exceptional conditions, and the successor of Delft3D 4 and SOBEK 2. During this two-day course, we will address key functionalities such as: 2D river hydraulics, 1D river hydraulics, and using OpenDA, Real-Time Control and Python scripting.


Course background

We will focus on hydraulic behaviour in rivers. Following a stretch of the Dutch river Waal, we will cover the basic functionalities required in consulting projects.

You will learn how to work with a model in 2D Flexible Mesh for accurate computations and with a 1D grid for fast computations. In this course we will introduce you to some of the similarities to both modelling approaches. We will address Real-Time Modelling of movable structures and the calibration of the model on measurements using OpenDA. Using the Python scripting functionality, you will accelerate your model set-up. You will be creating and adapting your 2D grid and changing the 2D schematisation, such as including a side-channel.

At the end of this intensive course, you have made your own model and applied the advanced functionality of Delft3D FM, which you can use for future reference in your projects.

Aim of the course

In this course participants learn:

  • to set-up river models (2D and 1D), from scratch
  • to use OpenDA for hydraulic model calibration
  • to use Real-Time Control for controlling structures
  • to use the Python scripting functionality
  • to get familiar with river hydrodynamics


  • Day 1: Introduction to software and theory, getting used to 2D, changing schematizations, Python scripting in Delft3D FM
  • Day 2: Getting used to 1D, Real-Time Control, calibration, batch simulations


Experience with river hydraulics and modelling is recommended.

The Instructors

Dr. Willem Ottevanger has many years of experience in Delft3D modelling of river dynamics, and has recently completed Ph.D. research on the parameterization of flow and morphology in strongly curved channels.

Anke Becker is an expert in hydrodynamic and morphodynamic modelling using state-of-the-art models such as Delft3D FM. She has worked on various rivers in Europe, North and South America, and Asia.

Jurjen de Jong is also an expert in hydrodynamic and morphodynamic modelling using state-of-the-art models such as Delft3D FM. He has worked on various flood modelling projects (1D-2D).
