| Summary: | This article aims to apply remote sensing and geoprocessing techniques to characterize the geologicalgeomorphological
interrelationships of the Japaratuba River Basin (BHRJ), located in the northeast of the state of
Sergipe. The methodology employed is the acquisition of SRTM data (Shuttle Radar Topographyc Mission) to extract
the drainage automatically, as well as the shaded relief that supported the automatic methods of extraction of geological
lines and representation of linear tops. The methods enabled semi-quantitative analyzes in the mapping of the
geological-geomorphological structures, where the rosette diagrams show that the three variables used in the drainage
survey, the linear structures and the linear representation of tops are grouped preferably in the NW-SE direction And a
subordinate trend in the NE-SW direction, due to the structural control exerted by the basement rocks. The study serves
as a source of information on the relief forms present in the region, as well as presents the risks of erosion, and
restrictions for the urban use and occupation of the Japaratuba River Basin. |
