AbstractThe 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.
ObjectiveAt 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.
ContentThe 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 revitalization project at the Alpine Rhine in Austria and Switzerland.

701-0405-00LFresh Water: Concepts and Methods for Sustainable Management3 credits2GC. Scheidegger, S. Fink, C. Weber, V. Weitbrecht
AbstractIn this course, we will discuss inland water ecosystems, their basic ecological characteristics, as well as their anthropogenic influences and changes. Case studies are used to discuss concepts and methods for sustainable management. The case studies are mostly from Switzerland and refer to the Water Protection Act and the Swiss Biodiversity Strategy.
Objective• basics concerning the functioning of the most important freshwater ecosystems
• basics of the sustainable management of aquatic ecosystems
• application of these principles with case studies
• critical analyses, organization of discussion groups
Content1) 1st lesson: Student working groups, working method
2nd lesson: Water Protection Act
2) Biodiversity in floodplains
3) Revitalization of rivers and lakes
4) Floodplain management and revitalisation
5) Protection of watercourses and lakes
6) River widenings and ramps
7) Restoration of the sediment dynamics
8) Changing discharge and temperature regimes in rivers and lakes
9) Planning and operation of pumped storage power plants
10) Water and health, including climate change
11) Fish migration in multi-purpose watercourses
12) Mire protection
13) Final/ Evaluation/ Feedback
