Lehrinhalt

- Introduction (engineer standards and guidelines)
- Ranging behavior and swimming performance of fish (capability of orientation)
- Different types of continuum disruptions (possible solutions, review of fish pass types)
- Basic principles of fish pass design (general regulations, important decision criteria and minimum standards)
- Specific values for construction of fully functional fish pass (recommended discharges...)
- Typical shortcomings in the execution of planning and construction of fish passes (sediment transport and periodic mainenance)
- Biotic verification of operation (basic principles and opportunities)

Exercise: Interpretation and evaluation of existing planning concepts
Field Exercise: Excursion to different fish pass types, biotic verification of operation (water depth, flow velocity, discharge,...)
