- Abstract
- A dam is a useful structure for human society, but does harm to wildlife such as migratory fish. Thus, in order to conserve fish habitat, fish passage can be constructed. For designing a nature-like fishway, through-flow velocity, which is defined as the average velocity over water flow through rock voids, can be a critical design factor. This study tries to propose a better formula in calculating the through-flow velocity. Based on 19 experimental data, this study proposed a slightly better formula than the original one in terms of root-mean-square error and determination coefficient.
