Detailed pressure and velocity measurement has been performed to determine the cavity length and the value of spread parameter σ which provided for the diffusion of curved jet issuing parallel to a flat plate. The assumption on the dividing stream-line and the velocity profile which formed along a flat plate after reattachment of curved jet have been assigned somewhat different form that of Bourque's and Sawyer's. The analysis for cavity length and such things which are based on above mentioned assumption agree quite closely with the measurement with regard that. Still more, in order to determine the critical water depth on which the direction of curved jet change, systematic experiment has been performed by means of changing little by little the water depth. The analysis for the criterion to change the direction of curved jet has been made on the point of view that a main cause of it are pressure down due to reversed flow which yield to be due to grant an entrainment of jet. The agreement with experiment is fairly by satisfactory.
