Abstract: 

In this study the results of an investigation carried out on radial gates for establishing the dimensionless stage-discharge relationship under submerged and free flow conditions is presented. For this purpose, indicial (power0 method of dimensional analysis and experimental data obtained from a laboratory flume was used to obtain the dimensionless equation that relates discharge (or critical depth) to upstream and downstream depth, gate width and gate opening. The fitted equations, was validated by field experimental data of some submerged radial gates of Doroodzan irrigation and drainage network in Fars province, southern Iran. Results showed that this equation can be fitted to field and laboratory data very well and can be used as a proper tool for management of radial gates in irrigation canals and dam gates.
