MODELING OF ONE DIMENSIONAL FLOW OVER SEMICIRCLE CRESTED WEIR PROFILE USING (HEC-RAS) PROGRAM

Abstract

A semicircle crest profile extending across full width of laboratory channel (suppressed) provides measurements of discharge – head under free flow condition. According to these measurements an empirical head – discharge relationship has been established. Dimensional analysis is carried out to establish independent parameter (R/H) which represents relative crest curvature and dependent parameter (
