In this experimental study, deferent design methods for baffle sluice gates have been investigated. Baffle modules are considered as a water delivery structure releasing a semi-constant discharge within specific upstream water fluctuations. According to the result of experimental data it was revealed that the performance of this structure is concurred with a desire volumetric water delivery structure and it can be widely used in irrigation channels. Module behavior has been evaluated for both increasing and decreasing of the water depth for deferent design methods. There was no significant effect due to increasing or decreasing of the upstream water depth on the hydraulic performance of the baffle sluice gate. Finally, it was demonstrated that choosing an accurate discharged coefficient can affect the design results significantly. In this regard, the best current design method has been improved based on choosing a suitable discharge coefficient.
