A flow duration curve (CDQ) illustrates the relationship between the frequency and the magnitude of the flows. The CDQ applications are of interest for many hydrological problems related to the generation of hydroelectric energy, sedimentation of rivers and reservoirs, water supply, irrigation. This study is an alternative for the problem of non-gauged basins by obtaining regional mathematical models with parametric equations, through methods of Quimpo, Mimikou and Suppo, Frannchini and Suppo.

The study was conducted in 11 watersheds of the South Pacific of Peru and a validation procedure was adopted using the Excel solver tool, in order to evaluate the method that best fits the CDC and thus make a comparison with the CDQ observed. The results provided a good reliability of the regional mathematical models obtaining the area and the percentage of bare area as the main parameters for the non-gauged sites. It was determined that the most robust parametric method is Franchini and Suppo with correlation coefficients for parameters a = 0.9199; b = 0.8633 and c = 0.8538.
