| Abstract: | The vertical-slot fishway and the natural imitated fishway were studied through hydraulics primary and secondary structure,length, bottom slope,slit width and pool room number of the fishway were optimized.The fishway optimization scheme for Yilan navigation-power junction project was proposed through comprehensive comparison of fishway general layout,pool room structure,discharge volume,water level, gradient ratio changes,flow velocity variation, fishway construction, operation and maintenance. |
