摘要：To contribute to the evaluation of hydrogeomorphological threats, a hydroclimatological and morphometric characterization of the basin of the San Julián River was performed using recorded landslide and overflow events that occurred in this system after activation by extraordinary rainfalls. The study methodology included geomorphological photointerpretation, the measurement and calculation of morphometric parameters, the estimation of the time of concentration, the characterization of the pluviometric regime, and the analysis of extreme precipitation events. The analyzed basin is a system in which hydrological responses are determined by morphometric characteristics; this trait is evidenced by the short time of concentration that results from this system's location in a mountainous environment and by the magnitude of extreme precipitation events.
