摘要：This paper compares the use of one-dimensional (1-D) and three- dimensional (3-D) numerical models to simulate the flow of a vertical-slot fishwa y. Prior to their application, the models are validated by comparing the predicte d data with experimental data from a physical model. Then the numerical models are appli ed to calculate four critical hydraulic design parameters of vertical-slot fishways, i.e., flow speed, water depth, turbulent kinetic energy, and energy dissipation rate. F urthermore, the authors developed rating curves for flow rate and energy dissipation ra te in terms of flow depth using data from the 1-D model. These curves have great utility for the operation of the vertical-slot fishway studied. The results indicate that 1-D mo deling can be a useful tool for preliminary conservative design arrangements of vertical-sl ot fishways, and that 3- D modeling can be a useful tool to enable accurate representati on of the critical hydraulic design parameters and selection of the most appropria te design.
