101-0269-00L River Morphodynamic Modelling
| Semester | Spring Semester 2024 |
| Lecturers | D. F. Vetsch, F. Caponi, S. Frei, D. Vanzo |
| Periodicity | yearly recurring course |
| Language of instruction | English |
| Abstract | The course teaches the basics of river morphodynamic modelling, relevant for civil and environmental engineers. The governing equations for sediment transport modelling in open channels and corresponding numerical solution strategies are introduced. Differences and capabilities of one- and two-dimensional approaches are presented. The theoretical parts are discussed by examples. | |||||||||||||||||||||||||||||||||
| Learning objective | The goal of the course is twofold. First, the students develop a throughout understanding of the basics of river morphodynamic processes. Second, they get familiar with numerical tools for the simulations in one- and two-dimensions of morphodynamics. | |||||||||||||||||||||||||||||||||
| Content | - fundamentals of river morphodynamic modelling (Exner equation, bed-load, suspended-load, closure relationships) - aggradation and degradation processes - differences between 1D and 2D approaches - river bars: characterization and prediction - non-uniform sediment morphodynamics: the Hirano model - short and long term response of gravel bed rivers to change in sediment supply - vegetation and morphodynamics interaction | |||||||||||||||||||||||||||||||||
| Lecture notes | Lecture notes, slides, and further educational material (scripts, videos, software, quiz) are provided in the Moodle page of the course. | |||||||||||||||||||||||||||||||||
| Literature | Relevant literature will be given during lectures or provided in the Moodle page of the course. | |||||||||||||||||||||||||||||||||
| Prerequisites / Notice | Exercises are based on the simulation software BASEMENT (www.basement.ethz.ch), the open-source GIS Qgis (www.qgis.org) and code examples written in MATLAB and Python. The applications comprise one- and two-dimensional approaches for the modelling of flow and sediment transport. Requirements: Numerical Hydraulics, River Engineering, MATLAB and/or Python programming skills would be an advantage. | |||||||||||||||||||||||||||||||||
