Design of Hydraulic Outlets Fish ladder Based on Hydrological and Hydraulic Uncertainties
Diversion dams prevent fish migration along rivers. Fish ladder is an appurtenance of a dam, which facilitates fish migration. Therefore, the environmental problem as result of the construction of dams is controlled by adding a flexible fish ladder, which contains an adjustable outlet for the fluctuating water levels. A fish ladder outlet is an overflow type outlet with free flow in the side channel, which is embedded perpendicular to the fish ladder. Wide fluctuations in the river flow affect the performance of the fish passage and can cause the fish ladder not to function as it was expected. The mean first order second moment (MFOSM) method was used to analyze the uncertainty of the water level profile and the crest elevation of the fish passage outlet. The optimal design of that structure was the result of applying this method.
