One of the first factors of control of the soil erosion must be the reduction of the flow of the torrent through constructions of canals method that according to Bertoni and Lombardi Grandson (1999), must be installed before any treatment inside of the soil erosion these canals will have to be constructed in from above part of the soil erosion of 20 the 30 meters of its headboard in way that the superior abrupt declivity of the soil erosion is stabilized the retention of the water well that it is obtained with the adequate use of the ground. In accordance with the authors the used vegetations more in the protection of the soil erosions are the grassy ones and some leguminosas between the grassy ones are distinguished capim blue (Dactihys Geomerata L); or capim bermuda shorts (Eynodon Dactylon L); between the leguminosas detaches: Cudsu (Pueraria Thumbergiana) and the diverse species of Lespedesas. For the vegetable implantation in the interior of the soil erosion it can also use land bags with seeds that can be implanted in the wall of soil erosion being necessary the withdrawal of all the cattle to prevent the extreme pisoteio in the land, or the construction of you surround around of wire of the affected area. Implanted the done vegetations the canals of retention of the flow of torrents diminish the concentration in the interior of the soil erosion are simpler the construction of the barriers in the interior of the same one, the canals can be of rocks, bags with land, screens of wire or pieces of trunks of trees these barriers diminish the erosion of the soil erosion and hinder that the sediments are loaded for the level of the base of the same one. For Lepsch (1999), three groups of practical conservacionistas exist that function in the erosive control being from edfico character, mechanical and vegetative. .
