The Study of Sluice Gate and Sharp-Crested Weir Through Hodograph Transformations

The problems of sluice gate and sharp crested weir were studied through hodograph transformations. Numerical calculations of the stream function in terms of hodograph variables were carried out after the hodographs were transformed into rectangles. Results were compared with the available experimental data and other results of calculations. Favorable agreement in all cases substantiated the fact that the method of hodograph transformation is effective in dealing with these problems strongly influenced by gravitation.
