A method for the design of slot orifice fishways for box culverts was developed. characteristics for a satisfactory fishway are identified. Appropriate graphs for sizing slot orifice fishways for a given performace capability of a fish are presented. The hydraulics of slot orifices constructed in the face of skewed wing-walls is explained. A table listing the swimming capability of various species of fish was compiled from existing literature. A hodograph for the wake boundary behind a flat plate placed normal to free surface flow was developed. A comparison of the size of wakes produced by a flat plate, a 90-degree wedge and a circular cylinder were made. The shape of wakes produced by embedded sphere with different degrees of submergence was also studied. (Author)
