A thorough understanding of paleohydrology is a key for water resources management and associated natural hazard risk assessments in the tropical climate of the Colombian Andes. In this study, we focus on the torrential activity of the Juan García Catchment (JGC, a tributary of the Cauca River) in the northern Central Cordillera. Historical data indicate the occurrence of torrential events over the last 70 years with diverse impacts degrees on the socio-economical structure of the local communities. Our research strategy in this study was the integration of multiple proxies to address the occurrence of historical torrential flow events in the catchment and peak discharge in this section of the Cauca River Canyon (CRC). We performed an integrated analysis using historical, geomorphological, stratigraphic, and dendrogeomorphic data. Geomorphologic and stratigraphic results confirm the long-term occurrence of torrential deposits at least from Late Pleistocene to Late Holocene. Hydraulic modeling and statistical analysis from tree scar heights suggest that peak discharge borders 123 m 3 /s for torrential events in the last decade, compared to base flow of 3-5 m 3 /s. We conclude that the high potential of dendrogeomorphic applications needs to be used more often to address natural hazard assessment in poorly gauged areas. In addition, the first dendrochronological dating of historical debris-flow deposits is presented as evidence for tropical tree rings as geomorphic markers. Integrated geomorphological and biological observations highly improve our understanding of the magnitude and frequency of torrential events in the tropical northern Andes.
