River Modelling (B-KUL-I0D25A)
Aims
The goal of the course is to teach the students how to use models for river analysis. While the main emphasis is on computational modelling, hydraulic scale modelling is also covered. Valuable insight is given in the design and operation of hydraulic structures, flood wave propagation and river flooding, the tidal influences, and sediment transport. The course considers different types of models used in the current practice, with emphasis on their limitations and the range of useful applications. Hands-on are given linked with the Integrated Projects (humid and semi-arid case studies), where common difficulties in model use are covered, thus building up the modelling skills, and at the same time building up physical knowledge and insight in hydraulic engineering problems.
Previous knowledge
Students are supposed to have basic knowledge in advanced mathematics, hydraulics, surface water hydrology, and water quality.

Activities
5 ects. River Modelling (B-KUL-I0D25a)
Content
- Overview of different types of hydraulic river and canal models and fields of application (1D, 2D, 3D);
- Application of a full hydrodynamic model for open channels and rivers (water surface profile computations under unsteady flow conditions, flood wave propagation);
- Implementation of hydraulic structures (weirs, spillways, control and regulating structures, sluices, bridges, dikes, culverts, etc.);
- Implementation of floodplains (quasi 2D, theory of 2D, use of DEM);
- Simplified modelling: theory of kinematic wave, reservoir routing, etc.;
- Solution schemes: theory of explicit versus implicit schemes, finite differences, method of characteristics;
- Theory of tidal influences;
- Sediment transport: theory of riverbed processes, channel stabilization, and dredging; and
- Principles of hydraulic similitude (theory of physical models, dimensional analysis).
Practical
Practical session to the course is linked with the integrated project (humid and semi-arid case studies), and includes the use of a full hydrodynamic modelling system (MIKE11), i.e.:
- Flow simulation for a selected river stretch:
* Using input from a conceptual rainfall-runoff model (link with the course “Hydrological modelling”) for an historical simulation period; and
* Using design hydrographs (for given return periods).
- Implementation of a floodplain along the selected river stretch, creation of a flood map and validation with an historical map; and Scenario-run: analysis of the influence of hydraulic structures (change in regulation on the flood modelling results).
