Abstract

In this research, the hydraulic characteristics of flow through circular culverts and over broad crested weir are experimentally investigated for 12 models. Stage discharge rating curve was presented for each model. The results show that for a specific head, the discharge of combined structure is greater than the summation of discharge of weir and culvert. Also, the discharge coefficient for the combined structure is varying from 0.25 to 0.73 and for the weir is varying from 0.25 to 0.63 and for the culvert is varying from 0.33 to 0.77. The dimensionless parameter H/D (head to diameter) has the greater influence on discharge coefficient. In addition, regression equations are presented for estimation of discharge coefficient.
