The Fact

To the being eliminated the vegetal covering, the natural balance if sees modified, and starts to receive minor arrives in port of organic substance initiating the process of degradation of the ground, modifying, therefore, the process-reply system. APPLICATION OF the TECHNIQUE, RESULTS AND CORRELATIONS OF the DATA the parcels had been installed in day 02 of April of 2010 and had been monitored biweekly up to 20 of March of 2011, in a period of one year, being these installed in 1 m each. Inside of parcel, had been distributed 25 bolts of metals with 30 cm each, that had been embedded completely in the form ground that only the superior part, that was colored with yellow ink, was visible. In the parcels one and three, we observe that a bigger compared loss of ground if with other tables existed below. The losses of ground in these parcels if give for the fact that, the ground was not covered by vegetation.

Thus, with the ground naked, the impact of the drop of rain makes with that the disaggregation of the ground happens, also known as effect splash. From this process, the process of the laminar erosion occurs subsequent, also known as erosion in sheet, which occurs through the diffuse superficial draining of the water of rain. When the laminar erosion happens, starts to appear the linear erosion, that is characterized by an intent draining of the water, through well defined lines of flow. In the areas of these parcels, we come across with different ground. In the area of parcel three, one exists ground encrostado, thus having, a bigger loss of ground. It is known that encrostadas surfaces are more compact, presenting bigger density and, consequentemente, minor infiltration. In the parcel one the density was of 0,70 g/ml while of parcel three g/ml was of 0,83, thus, explaining the biggest loss of ground in parcel three.
