Abstract: Sharp open channel bend flows are highly three-dimensional because of the combined effects of secondary flow, large free-surface variations, and flow separation along the inner bend wall. A comprehensive analysis was ...

Abstract: Sharp open-channel bends are commonly encountered in hydraulic engineering design. Disturbances such as secondary flows and flow separation caused by the bend may persist for considerable distances in the downstream channel. ...

Abstract: Weirs and notches are efficient devices for measuring flow rates. Banks of slit weirs forming multislit weirs allow both precise discharge measurements in a very large range of flow rates and permit a good flow regulation. ...
