Mudslides and rockslides from gullys are frequent catastrophic events in Peru. Therefore, this research consists of knowing the effects of debris flow generates in a perimeter wall located in the lower area of Rayos de Sol gully in the district of Lurigancho-Chosica. The procedures for this investigation consisted of determining following: geomorphological characteristics of gully, maximum flows for the years 2015 and 2017, and return periods (Tr) of 25, 50, 100, 200 and 500 years using HEC-HMS, Manning's coefficient and rheological parameters. Then, the aforementioned parameters were validated by comparing the height of the flow observed in the field with the height simulated in HEC-RAS for the 2017 event. Later, for the 2015 event, the effects of debris flow in a perimeter wall (6.00x2.50x0.13 m) were analyzed, caused by a flow rate of 1.30 m3/s, in which a height of 1.13 m, reached by the mixture on the wall, generated an impact force of 3.45 kN and rock impact force of 16.87 kN, which caused collapse of the wall, since the distortion limit was exceeded with a displacement of 45.52 mm. It was also established that rock impact forces and flow forces are a function of mixing depth with a correlation coefficient of 0.9612 and 0.8593, respectively.
