The study area is located in the domain of the savannas, plateaus and residual relief sustained by rocks of the Bacia Sedimentar do Paraná.
Research started 10 years ago and from geomorfological mappings, classification and zoning of the gullies, sample hidrographical basins were established: The Boa Vista Brook basin, in the municipal district of Prata, and the basin of the Douradinho brook, in the municipal district of Uberlandia.
Studies in the Douradinho Brook showed receding of the banks of the gully of up to 3.00m, between 1997 and 1998. The erosion incursions occur of walls due to a line of pipe flows. Underground caves develop originating from the dynamics of the ground water causing seepage erosion. Such processes are promoting interfluvial dismantling because of receding headwaters as well drainage caption. The Boa Vista Brook presents, in the segments of the coluvial ramps and at the base of cliffs, gullies with a depth between of 10 to 20m dating back from 20 to 50 years with a receding headwaters of up to 4.70 m, between 1996 and 1998. In the monitoring of the gullies, an expressive dynamic was noted in some digits conditioned by the superficial runoff and pipe flows.
An intensification of the erosive fronts by gully in the savanna shows a direct correlation to receding drainage headwaters at several dissection levels indicating an erosive retake set off through natural processes and accelerated in the last 100 years by the use and inadequate occupation of the soil.
