Soil and water are vital natural resources. However, due to their indiscriminate use, these resources are being seriously threatened. Therefore, it is essential to manage them in a sustainable way and leave them for future generations. Population and agricultural areas have expanded, deforesting native landscapes for cultivation and pastures. As a result, soil loss from agricultural areas is increasing the amount of sediment transport in water courses. The objective of this study was to quantify soil loss and sediment yield from the Corrente dos Matões sub-basin (CMSB). These measurements are essential to quantify the environmental impact of advancing agricultural frontiers. The Universal Soil Loss Equation (USLE) was applied due to its wide use, compatibility with GIS, and data availability. The suspended sediment transport was calculated by collecting samples with DH-48 sampler. From the application of USLE, the average soil erosion contributed very little to sediment delivery in the watercourse, with a magnitude of only 0.37 t ha⁻¹ year⁻¹. The highest soil loss was associated with greater slope and was observed in areas with agriculture or under the absence of vegetation cover. The low transport of suspended sediments in CMSB is due to the existence of preserved sites. About 99% of the sub-basin had a low degree of erosion. The high degree of soil loss was attributed to the cliffs and the development of agricultural activities leaving the soil uncovered. This work will help identify the most susceptible areas to water erosion for optimizing the allocation of financial resources for the preservation of this natural resource.

土壤和水是重要的自然资源。但是，由于滥用它们，这些资源正受到严重威胁。因此，以可持续的方式管理它们并将它们留给后代是至关重要的。人口和农业面积不断扩大，砍伐了原始景观，用于种植和牧场。结果，农业地区的土壤流失增加了水道中泥沙的输送量。这项研究的目的是量化Corrente dosMatões子流域（CMSB）的土壤流失和沉积物产量。这些测量对于量化农业前沿发展对环境的影响至关重要。由于通用土壤流失方程（USLE）的广泛使用，与GIS的兼容性以及数据的可用性，因此得以应用。通过用DH-48采样器采集样品来计算悬浮泥沙的输送量。从USLE的应用来看，平均土壤侵蚀对水道中泥沙输送的贡献很小，仅为0.37吨公顷^-1年^-1。最高的土壤流失与更大的坡度有关，在有农业的地区或没有植被覆盖的地区观察到。CMSB中悬浮沉积物的低迁移归因于保存地点的存在。大约99％的流域侵蚀程度很低。高度的土壤流失归因于悬崖和农业活动的发展，没有发现土壤。这项工作将有助于确定最容易遭受水蚀的地区，以优化财政资源的分配，以保护这种自然资源。
