Currently renewable energy resources are of main interest and among them small hydro power plants are the most important hydrologically speaking. In design process the negative impacts of hydropower dams and stations on ecosystems, particularly on fish migration must be accounted for and adequate protection measures must be achieved. The solutions for restoring fish migration are almost invariably specific to each site because of a unique combination of local features. The identified solutions should take into account all relevant factors including the nature of the obstructions, target fish species, hydrological and hydraulic conditions. This paper deals with the types of fishways suitable for the use in the small hydro power plants on the continental Croatian territory, such as: pool fishways, vertical slot fishways, obstacle fishways and rock-ramps (natural) fishways. An analysis of the required shape, size and length of the fishways conditioned by fish species in continental Croatia was conducted depending on the head that has to be overcome. The presented results can be used for preliminary selection of possible solutions in the early stages of the design. |
