摘要：This research seeks to assess possible neotectonic influence in the formation of sandization in southwest ofRio Grande do Sul. The main objective of this research is to identify points of neotectonic “anomalies” insegments of drainage and make the relationship with the points of occurrences of sandization. Theidentification of these points of failure was obtained through DEM (Digital Elevation Model) as subproductof the SRTM image. The analysis was undertaken based on the employment index RDE (Relationshipslope-extension) applied in segments of drainage. The drainages were scanned images from shaded withdifferent contrasts, SRTM products. The results indicate a possible ralation of the neotectonic in the genesisof the sandization, because the points of possible neotectonic “anomalies” identified in the watercourse islocated near the areas with outbreaks of sandization.
