Process of analysis for evaluating fish protection and fish downstream migration

Infographic in a manual on site specific evaluations of the efficiency of fish protection and bypass systems
The infographic presents the five-step process for deriving the final statement on function for the investigation of biological downstream migration by fish.Read more

Steps and criteria used to develop the design for an investigation of fish downstream migration

Infographic in a manual on site specific evaluations of the efficiency of fish protection and bypass systems
The infographic presents the process and criteria to be considered for the design development for an investigation of fish downstream migration.Read more

Beispiele von Standorten unterschiedlicher räumlicher Komplexität

Infographic in a manual on site specific evaluations of the efficiency of fish protection and bypass systems
The manual helps to examine a wide range of sites, including complex spatial constellations. Sites with transverse structures as well as hydro power plants and tangential water withdrawal systems can be evaluated. This infographic shows site examples of different spatial complexity.Read more

Spatial scale and areas of investigatin - Example: hydro power plant in combination with a weir

Infographic in a manual on site specific evaluations of the efficiency of fish protection and bypass systems
The infographic visualizes the four spatial areas of investigation of the manual in an examplary fashion. The spatial levels are: site, corridor group, corridor and corridor component.Read more

Wirkungskette über mehrere ökologische Ebenen hinweg

Infographic in a manual on site specific evaluations of the efficiency of fish protection and bypass systems
The infographic visualizes interactions across several ecological levels. The death of individual fish reduces the population size of its species. Because of multiple ecological interactions this can cause changes in the entire biocenosis.Read more
