In this study, a literature review is conducted in terms of assumptions, approaches, and various calculation methods used for the analysis of flow over conventional and stepped type spillways. In guidance of this review, a software is developed to perform such analyses with the set of given data by the user, and display results with some tables and figures. To this end, water surface profile over the spillway face is determined considering air entrainment process, pressure distribution over the crest under various flow conditions are checked, and the possibility of cavitation along the spillway chute is searched. Besides, hydraulic jump over the stilling basin is determined and necessary stilling basin level is calculated according to the given downstream energy level. Similar computations are also conducted for stepped spillways such that a designer can perform quick successive analyses for various alternatives. The software is applied to an example to illustrate its use and discuss the results of the analyses.
