Experimental and numerical investigations of a surge in a hydraulic turbine draft tube were carried out using a subscale model. It has been confirmed that the draft tube surge occurs at wide range of the operation condition from the low flow rate through the over load conditions. The frequencies of the surge are different from those of the vortex rope precession. Additionally, dynamic characteristics of the cavitation in the draft tube were examined experimentally by imposing flow rate fluctuations.
