Abstract: The requirements, which ensure good water quality in natural bodies of water in Europe, also involve restoring the ecosystem and therefore free migration of fish upstream and downstream. As a consequence, measures must be taken and structures must be built which allow for this migration. This paper provides a very detailed overview of the resulting geometric and hydraulic specifications for such structures. On the basis of the results of a vortex hydropower plant simulation, the plant’s suitability as a fish ladder is underlined, as all requirements in terms of flow velocity are met.
