In water resource management the main basic requirement is the estimation of runoff resulted from precipitation. In present study, runoff from Chaskaman catchment estimated using different empirical methods such as Inglis and DeSouza formula, Khosla’s formula, Coutagine relationship, Department of irrigation India, and Strange’s table method. Hydrological data such as observed daily runoff of 15 years (2000-2014) was collected from Superintending Engineer, Department of Irrigation, Government of Maharashtra, Pune. Performances of the empirical methods were evaluated using various statistical performance evaluation indices. From the result of the study, it is concluded that, the Coutagine relationship is the best method for estimation of runoff in Chaskaman catchment. In this study, from the results of the statistical performance evaluation Inglis and Desouza method indicated as the second best method after Coutagine relationship, for runoff estimation in the catchment area. Department of irrigation India and Strange’s table method shows slightly high runoff as compared to all other methods.
