Abstract: Several types of flow‐measurement structures are used in rivers. One of the more common flow‐measurement structures is the critical‐depth flume. By definition, the velocity increases through the contracted section of the ...

Abstract: An available turbulence method is used to prove that in plane flows between two boundaries with asymmetric roughness the plane of maximum velocity is not the plane of zero shear stress. By dividing the flow at the plane ...

Abstract: A new empirical equation is proposed for predicting critical flow velocity in slurry-transporting horizontal pipelines. An analysis of the settling velocity of solid particles, including the effect of solid particle ...

Abstract: A series of laboratory experiments were carried out in a flow-measurement flume of a rectangular compound cross section to investigate the effect of the throat width and step height on the values of discharge coefficient, ...

Abstract: The studies on labyrinth side weirs have received considerable attention in existing literature. A mobile bed, which causes significant morphological bed changes, can be induced by the side overflow weir. In this study, ...

Abstract: Greater or more constant discharge can be achieved at lower upstream water depths over the weir crest by increasing the effective lengths of labyrinth side weirs. Labyrinth weirs have unevenly shaped crests, resulting in ...
