Abstract

The characteristics of the flow in vertical slot fishway depend mainly on the specific pool design, such as the geometry of the pool. We present the results of a study on comparison between four different designs of vertical slot fishways. The results indicated that central baffle cannot cut down the value of the velocity substantially, but it can stabilize the flow pattern, and it can make energy dissipation uniform. Simultaneously, slope has significant impact on hydraulic characteristics like velocity and flow pattern in the fishway. Of the four designs studied, design 4 is recommended for practical use, in terms of velocity and flow pattern.
