The watershed of La Copa Reservoir is located in the central province of Boyacá’s department. It acts as a storage area and water recharge, which is used for irrigation by the municipalities of the highlands of Chicamocha. One of the main reasons of soil loss in the hydrographic watersheds is water erosion due to rain or erosivity. The goal of this research was to determine the degree of erosivity in the watershed of La Copa Reservoir. The climatic aggressiveness was evaluated and mapped by the MFI index, the rainfall erosivity by the R factor, and the concentration of rainfall by the PCI index. The results showed that in the municipalities of Toca, Siachoque, Tuta and Soracá, the aggressiveness of rainfall is moderate, while in the rest of the watershed, the aggressiveness is low. The R factor indicated that the whole watershed has a low risk of erosivity. Likewise, the PCI showed that rainfall in the watershed is distributed over several months, which reduces the risk of watershed erosion. We conclude that even though the risk of erosivity is low, it is necessary to study other factors of soil loss to obtain a more exact view of the watershed.
