Soil erosion is extremely variable, and this variability is due to differences in the soil surface conditions along the basin, which directly affects surface runoff. Thus, the objective of the work in question was to carry out a bibliographical survey on soil erosion in the semiarid geographical basins to better understand the subject and the problems involved. Erosion is seen as a process of wear, transport and sedimentation of soil, subsoil and rocks caused by water, water erosion, or wind, wind erosion, as well as the action of living beings. In Brazil, water erosion is of greater interest, largely in the tropical region, because it is more frequent, acts more quickly and causes high losses both in the agricultural sector, as well as several other economic activities besides the environment itself. Regarding the semiarid region, erosive processes become unsettling, since the soil is increasingly vulnerable due to the intensifying anthropic action and the very fragility of the soil material.
