چکیده انگلیسی
One of the major problems in fishway design is that optimal parameters depend on an interplay of hydraulic and biological variables. This study presents a methodology for evaluating fishway designs in terms of the swimming capabilities of the target species. Specifically, we have evaluated two vertical-slot designs whose hydraulic properties were empirically characterized in a previous study. In view of these empirical data, for each design we have estimated (a) minimum discharges giving minimum fish-acceptable depths; (b) maximum pool sizes ensuring flow velocities low enough to be overcome by the fish; (c) maximum pool sizes ensuring turbulence low enough to be acceptable to the fish. These design constraints are calculated for different slopes (â¼6 or â¼10%), different water temperatures (10, 15 or 20 °C), and different fish lengths. This methodology constitutes an effective means of taking fish swimming capabilities into account at the fishway design stage.
