Descripción

Soil loss due to erosion by water is a problem that causes significant economic losses; for this reason, the aim of this study was to quantify soil loss in the Agustín Melgar watershed in Hydrologic Region number 36 by applying the Revised Universal Soil Loss Equation. A geographic information system was used to obtain distributed parameters of the studied equation. The results show that there are different soil loss levels in the watershed under study, ranging from “very low” (losses lower than 5 t·ha-1) to “extreme” (losses greater than 200 t·ha-1).
