Model tests for the opening-discharge ratio of a radial gate / A. Führböter ; F. Büsching
For the radial gates of the Welbedacht-Dam in Southafrica, a calibration curve for the relation between gate opening and discharge under constant head condition was established. using a Scale model 1 to 50 for one weir. The underflow was found to be stable for all gate openings; some vortex formation in the head water did not disturb the discharge-opening ratio.
