Different flow-altering methods, such as W−Weirs, have been developed to reduce erosion. For this study, we performed two experiments: (1) installing a W−Weir in various positions determine the best angle for placement, and (2) investigating variation of flow patterns bed shear stress distribution 90-degree sharp bend by measuring 3D components velocities, with without where greatest scour dept...

For efficient use of water, accurate measurement of flow in (field/laboratory) channels is required for many water resource projects. The present work is aimed to study the flow characteristics of a twin plate weir (two sharp-crested plates are placed one behind the other at some distance) under free and submerged flow conditions. Experiments are performed with four spacing of the twin plate we...

With the continuous operation of check dams, silting elevation whole dam gradually increases. When height is close to broad-crested weir, it will result in a large change hydraulic characteristics original flow pattern. For subsequent reinforcement work, necessary know how excessive sediment deposition affects overflow from weir into spillway. However, few studies about discharge coefficients a...

The effect of the outlet weir height on sieve tray performance is described in this paper. The studies were made to investigate the effect of the outlet weir height on sieve tray mass transfer efficiency and hydraulic performance. Tests were conducted in the 1.22 m diameter section of the Fractionation Research, Inc. (FRI) low-pressure column. Sieve trays with nominal hole areas of 14%, 13%, an...
