A rainfall threshold for the occurrence of landslides in manmade slopes in residual soils in the northwest of Colombia

The purpose of this paper was to determine a rainfall threshold to estimate the probability of occurrence of landslides in roadway slopes. The analysis was performed for a roadway slopes excavated in residual soils derived from igneous intrusive rocks from the stock of Altavista, Medellin, Colombia....
