Hydrodynamics 1D/2D Floodings

Hydrodynamics – 1D/2D Floodings

A lot of effort is put in flood prevention, but what happens when a dike breaks or a water system
flows over? With SOBEK-Rural Overland Flow you can simulate these calamities to investigate
effect of measures, improve risk management and formulate policy. During the one day course you
will work with SOBEK-Rural Overland Flow in combination with SOBEK-Rural 1DFLOW. Aim of this
course is to improve your modelling skills and to get more out of SOBEK-Rural Overland Flow.

Course background

The course focuses on SOBEK-Rural Overland Flow (2D) module is fully integrated with SOBEK-Rural 1DFLOW, SOBEK-River 1DFLOW and SOBEK-Urban 1DFLOW for accurate flooding simulation. It is especially designed to simulate dam breaks and dike breaks. It is based upon the complete de Saint Venant Equations. It simulates steep fronts, wetting and drying processes, sub critical and supercritical flow, handles multi domains and even nested, and includes rainfall on the 2D grid.

Subjects

The course consists of short presentations and practical exercises. Participants will work on subjects like:

• Explanation on 2D flow functionalities (options in coupling 1D and 2D flow, nested grids), including theoretical background;
• Aspects of importance in constructing a good 2D flow model;
• Exercises with different options in combining 1D and 2D flow;
• Exercise with nested grids.

Participants

The course is aimed at river engineers and modellers from consultancy and engineering companies, provinces, water boards and universities. You are expected to have some experience with SOBEK, or to have gone through the SOBEK tutorial “Hydrodynamics – 1D/2D Floodings”. The course is meant for people who have experience with SOBEK 1D flow models.

Aim of the course

In this course participants learn:

• The hydraulic background of overland flow to improve your insight;
• How to use 2D functionality to improve your accuracy of your investigation;
• How to check your schematization and results to improve the reliability of your advice;
• How to visualize your results to communicate your findings;
• Tips and tricks to save time.
