This work was carried out in the Huaycoloro stream which is part of the basin that bears the same name located in the district of Lurigancho-Chosica in the province of Lima, where it seeks to explain the criteria of debris flow modeling applying two mathematical models analysis for this type of flows. The first one with free access KANAKO-2D and the second one with paid access FLO-2D, both models require common input data such as digital terrain topography, channel roughness values, hydrographs for different return periods, rheological properties of the two-phase fluid (water-sediment) among others. For this research, a Digital Elevation Model (DEM) was carried out with spatial resolution of 5mx5m, where the percentage of sediment concentration is added to the liquid hydrograph to represent the debris flow in the corresponding models, the Rheological parameters (viscosity, concentration percentage, yield stress) are taken as a reference, comparing results of studies carried out in the stream with validated samples collected from the literature. Finally, with the processing of these data in both programs, obtain results such as flow depth, velocity, sediment concentration, impact force, etc. Of which, this article focused on the comparison of the depth of the debris flow of the respective modeling with a real event, where for the Kanako-2D, Flo-2D and the field measurement an average depth of 2.20 is presented , 2.50 and 2.60 meters respectively, so it is concluded that the Flo-2D program is more accurate in its modeling for this particular situation.
