| Resumen: | In: López Rendón, Jorge E, ed. Geología ambiental y geomorfología aplicada en Colombia. Medellín, Antioquia. Universidad EAFIT, oct. 1991. The 230 mm rainstorm which on September 21st, 1990 in the upper watershed of San Carlos River produced hundred of shallow mudflows and mass movements caused by margin undercutting and channel deepening. A large amount of sediments were transported, from blocks with diameters up to 4 which destroyed the Caldera Plant to fine sand, silt and clay which reached the Punchina Reservoir. Available knowledge did not apparently permit the prevision of such event. The building of the plant affected the watershed only locally. The role of vegetation with respect to the occurrency of mudflows does not seem to have been important; however, its destruction certainly contributed to increase runoff. Knowledge about regional meteorology and hydrology should be improved, as the understanding of processes as chemical weathering, soil formation, erosion and sedimentation (AU). / ANTIOQUIA |
