Quasi-Theoretical End-Depth-Discharge Relationship for Rectangular Channels
Publication: Journal of Irrigation and Drainage Engineering
Volume 129, Issue 2
Abstract
End depth of a free overfall is used as a flow-measuring device in open channels. A quasi-theoretical method for predicting end-depth-ratio (EDR), i.e., ratio of the end depth to the critical depth, and end-depth-discharge (EDD) relationship in terms of pressure coefficient in subcritical and supercritical flows in rectangular channels is presented. The brink pressure distribution coefficient used in the method is evaluated from experimental data. Predicted values of EDR and EDD are compared with the available experimental data.
