Analysis of discharge characteristics of a symmetrical stepped labyrinth side weir based on global sensitivity

open access: yesJournal of Hydroinformatics
In this paper, the discharge coefficient prediction model for this structure in a subcritical flow regime is first established by extreme learning machine (ELM) and Bayesian network, and the model's performance is analyzed and verified in detail.

Discharge Coefficients of Oblique Weirs

open access: yes, 2011
Oblique weirs are those weirs placed at an angle with respect to the channel centerline. They can be used in canal applications where more discharge is needed, but there is limited freeboard. The discharge coefficients were determined for 54 different weirs by measuring total head for various flows over each weir. These weirs included sharp, half round

Discharge coefficient of side weirs in curved channels

open access: yesProceedings of the Institution of Civil Engineers - Water Management, 2012
Side weirs are flow diversion devices commonly used in irrigation, land drainage and urban sewage systems. It is essential for hydraulic and environmental engineers involved in the design of side weirs to predict the discharge coefficient correctly. The aim of this study is to present an accurate equation for discharge coefficients along the bend of ...
