Natural disasters associated with torrential floods are considered among the most destructive phenomena in Colombia due to the country’s geological and geomorphological characteristics. This study aims to identify the geomorphological parameters influencing the occurrence of these events in the Naranjal basin, located in Quetame, Cundinamarca. To achieve this, photointerpretation processes were carried out to identify geomorphological units at a scale of 1:10,000, and morphometric parameters of the basin were calculated to analyze the dynamics that generate torrential flood processes. The study revealed that the Naranjal basin is almost entirely dominated by a denudational environment, where intense weathering and erosion processes are facilitated by steep terrain and low drainage capacity. Its elongated shape and morphometric parameters indicate a slow hydrological response, which increases the risk of torrential floods during intense rainfall events.
