| Abstract | The lecture addresses the fundamentals of river engineering to quantitatively describe the flow of water, transport of sediment and wood, and morphological changes such as erosion and deposition processes associated with river structures. In addition, design guidelines for river engineering structures are introduced. | |||||||||||||||||||||||||||||||||||
| Learning objective | At the end of the course, the students will be able to: - recall and describe the fundamentals of transport processes in rivers, - apply different calculation approaches and methods to tackle river engineering problems and tasks such as the discharge capacity of a river, scour estimation, or sediment budget of a river, - design and dimension river engineering works needed to influence the processes in watercourses, and - determine the interaction between flow (discharge), sediment transport, wood transport and the resulting channel evolution. | |||||||||||||||||||||||||||||||||||
| Content | The first part of the lecture introduces the fundamentals of river engineering, such as methods to determine and calculate the river discharge, or sampling methods to characterize the bed material. In addition, the transport processes of sediment (bedload and suspended load) and wood in rivers will be examined, including the principles of incipient motion, and initiation of erosion or deposition processes. In the second part of the lecture, the methods will be explained to quantify the bed load budget and the morphological changes (erosion, deposition) in river systems. Specifically, natural channel formation processes, different bed forms and plan forms of rivers (straight, meandering, braided) are examined. The last part of the lecture focuses on the design of river engineering structures, including examples from an ongoing flood and river rehabilitation project at the Alpine Rhine in Austria and Switzerland. | |||||||||||||||||||||||||||||||||||
| Lecture notes | Lecture slides can be downloaded via Moodle. Remark: The slides support the learning process with the most important basics. They do not replace attendance and active participation in class, which is a basic requirement for successfully completing the course. | |||||||||||||||||||||||||||||||||||
