An experimental program was performed with hard-chine catamaran models in regular waves. The distance between the demi-hulls of the models was changed to assess its effects on the wave-induced motions. The results allowed the study of some aspects related to catamaran motions, like the interference between the hulls and resonance frequencies. The experimental results are compared with calculations performed with a recently developed code based on a two-dimensional potential flow theory in which viscous forces are included through a cross-flow drag approach. The effect of the hull distance in the heave and pitch motion responses and the importance of the viscous forces in such hull configurations are shown.

This paper presents the results of an experimental study on 18 designs of vertical slot fishways. Based on these results, it appears that a width of 8b0 and a length of 10b0 for the pools, where b0 is the slot width, are satisfactory, and minor variations can be made to these dimensions without affecting their satisfactory performance. In the two general groups of designs, design 6 in the first group and designs 16 and 18 in the second group are recommended for practical use. Key words: fishways, hydraulics, turbulent flow, open-channel flow, hydraulic design.
