Abstract: Self-excited oscillations of flap gate are observed in many intake struc tures such as weirs and dams. The analysis on this oscillation has been done partly by author about ten years ago (1974). But this analysis can not make clear all of the occurence of self-excited oscillation in flap gate and nappe oscillation. In this time another analysis has been done on this phenomenon by sdding to the former analysis and the better results to be able to explain the almost of the unstable phenomena on this oscillations. Namely my exper imental results since 1972 to 1974, H. Ivan Schwartz's "K+1/4" law (1964) and Petrikat and Unny's "K+3/4+B" law (1965) are certified crearly by this analysis.
