WebThis paper presents the results of an extensive laboratory study aimed at improving the design of Denil fishways. For the standard design of the simple Denil, an equation has been developed between the dimensionless discharge Q* and the relative depth of flow d/b for d/b as large as 5.5. The normalized velocity distributions in the centerplane of the Denil … WebMar 6, 2024 · Worked example of how to calculate the flow depth at a given discharge for a rectangular open channel using Manning’s equation the pace method
