The Cañar River lower basin is a coastal flat area with a high hydro-economic potential, however this zone is vulnerable to flooding. The Ecuadorian Government invests in a flood control project. The project design alternatives need testing in a physical model for supporting the final design. The variables related to the flow through the radial gates of the diversion works are investigated in a physical model. A discharge curve was calibrated for the gate operation. In addition, the best gate location was determined, as well as the optimum still basin depth. Unusual osculation with negative flow directions were found for specific tests. This phenomenon has a scour effect. In order to solve this problem, changes in the geometry of the still basin entrance are recommended by adjusting it to the flow profile.
