- Abstract
As a special means of river restoration in hydraulic engineering construction, the basic function of culvertnot only provides water channels for the system of roads and bridges, but also to ensure the successful passage through the barrier for various local aquatic animal. Since there are few literature referring to the hydraulic design of culvert fish passage in China, so the theoretical basis that can provide reference for the construction of culvert fishway is limited. In this paper, the characteristics of hydraulics and flow fields for the classical baffle systems of culvert fishway, which include the following three baffles; spoiler baffle, Alberta fish-weir (AFW) and Alberta fish baffles, were summarized on the basis of summarizing the foreign experimental data and the relational expressions between flow rate, water depth, slope and velocity were obtained, the working performance of the baffles was compared and analyzed as well. Relative data and conclusion could provide a theoretical basis and reference for the internal transformation and hydraulic design of domestic culvert fishway.
