Numerical evaluation of turbulent flow in a circular conduit along a side weir
Applied Water Science, 2019 Side weir is used as a slot in the side wall of the main channel to direct excess water that is above the weir crest. Such structures are used in control of flow level in irrigation, drainage networks and urban sewage disposal systems.

Uncertainty analysis of discharge coefficient of circular crested weirs [PDF]
Applied Water Science, 2021 The circular crested weir (CCW) has been introduced as weirs having a high discharge coefficient (Cd). The ratio of flow head to the radius of the crest (H/R) is the most important parameter affecting the Cd, that the $${\text{Cd}} \approx a\left( {H/R} \

Hydraulic Characteristics of Flow over Circular Crested Weirs
Science Journal of University of Zakho, 2016 In this investigation nine models of circular crested weir were constructed and tested during an experimental study. Crest radius( r) of the weir was varied three times; 2.5 cm, 3.1cm and 3.75cm.
