What the plantation in level, the plantation in bands and the terraeamento have emcomum? What these prticasde conservation of the ground have in common? This text is the one attempt to display this. Simple Emtermos, these three practical ones of conservation of the ground has the objective to dediminuir the speed of the superficial draining in such a way the proporcionarmais time so that this can be infiltrated in the ground. Noplantio in level this is obtained by means of the plantation lines that atuamcomo small frequent obstacles that, as displayed, act delaying avelocidade of the torrent that goes down the source. Figure 1. Plantation in level, that is, respecting curvasde level.

In it bands plantioem, the deceleration of the torrent are gotten by means of the creation of faixasde bigger covering of the ground (Figure 2). When the water of the torrent reaches asfaixas of high covering of the ground, it tends to reduce the speed being had maiorchance to infiltrate in the ground. Figure 2. Plantation in comdiferentes bands coverings. When the water of the torrent reaches the bands of maiorcobertura and greater rugosidade of the ground, it tends to suffer to reduction davelocidade and if to infiltrate. It also observes that it has the plantation in level in this photo.

Osterraos acts as back of a book that reduce the speed of the water of the escoamentosuperficial (Figure 3). In the region before the back of a book, isot is in the canal the water can seacumular and if to infiltrate or, in some cases, this water can suffer draining to eser made use in bodies dgua. Figure 3. Terraoagrcola: it notices the back of a book that is constructed to receive the water from the torrent to epermitir that this if accumulates in the canal and can be infiltrated. Ofato of these techniques of conservation of the ground to the same have objective nosignifica that must be used or one or another one. Perhaps check out koch for more information.
