Design of Side Weirs in Subcritical Flow

Urban Drainage Modeling, 2001
Side weirs are flow-diversion and flood control devices widely used in urban drainage, land drainage, and irrigation systems. The De Marchi equation is widely used for computation of side-weir flow. However, in this equation the variation of flow depth with longitudinal distance is expressed in implicit form.

Discharge Coefficient of Rectangular Side Weirs

Journal of Irrigation and Drainage Engineering, 1994
The characteristics of flow over side weirs are taken into account to determine the discharge coefficient for subcritical flow conditions under the assumption of constant‐specific energy. The main‐channel discharge, length of the weir crest, and sill height of the weir are treated as the controlled variables.

Nonlinear PLS Method for Side Weir Flows

Journal of Irrigation and Drainage Engineering, 2006
Side weirs are flow-regulating devices commonly encountered in hydraulic engineering. In the past, the discharge coefficient for flow past a side weir was investigated experimentally by many researchers. In this study, a modified discharge coefficient Cd for side weirs in rectangular channels and circular channels is defined.

Subcritical Flow over Rectangular Side Weir

Journal of Irrigation and Drainage Engineering, 1994
Side weirs are flow‐diversion devices widely used in irrigation, land drainage, urban sewage systems, and so forth. For computation of side‐weir discharge, the de Marchi equation is widely used. Using de Marchi's equation, various investigators have related the weir discharge coefficient with the main channel's upstream Froude number.

Experimental Investigation of Flow Over Side Weirs

Journal of the Hydraulics Division, 1976
Observations at numerous cross sections in a side weir channel showed that the total energy of flow decreases substantially along the channel, contrary to the assumption that has frequently been made. The decrease in total energy occurs because the longitudinal component of velocity of the spill flow is greater than the longitudinal velocity of the ...
