Resumo: Soil erosion is a generalized environmental threat, it is important your knowledge to the maintenance of terrestrial ecosystems. The objective of this study was to evaluate the importance of water erosion in the semiarid environment scenery in hydraulic conditions, soil breakdown of relationships and flow resistance in the presence of caatinga biome and vegetable residues in interrill erosion. The experiment was conducted in semi-arid watershed of Jacu stream, Serra Talhada, Pernambuco, for this experiment were installed 16 experimental plots subjected to simulated rainfall events for a period of 40 min, The used treatments were caatinga semi-shrub; litter; canopy; and uncovered soil. The values obtained with respect ace runoff on the vegetation elements had lower velocities 0.84 mm compared to uncovered soil 0.70 mm, checking also that the litter and the effect of the canopy of the semi-shrub caatinga succeeded in slowing the flow depth 0.015 m s-1, similarly, the flow rate under these conditions was significantly lower 1.27 x 10-5 as well as the soil losses 0.59 t ha-1. This shows how important of vegetation and vegetation cover on soil protection in the semiarid.

O objetivo do presente estudo foi avaliar a importância da erosão hídrica no cenário do ambiente semiárido nas condições hidráulicas, relações de desagregação do solo e de resistência ao escoamento na presença do bioma caatinga e de resíduos vegetais na erosão em entressulcos. O experimento foi realizado na bacia hidrográfica semiárida do riacho Jacu, Serra Talhada, Pernambuco, para tanto foram instaladas 16 parcelas experimentais que foram submetidas a eventos de chuva simulada por um período de 40 min, os tratamentos utilizados foram caatinga semi-arbustiva; dossel da vegetação; serrapilheira; e solo descoberto. Os valores obtidos com relação as lâminas de escoamento superficial sobre os elementos de vegetação tiveram alturas superiores em média 0,84 mm, com relação ao solo descoberto de 0,70 mm, verificando também que a serrapilheira e o efeito do dossel da caatinga semi-arbustiva conseguiram retardar a lâmina de escoamento, 0,015 m s-1, de igual forma, a vazão foi significativamente menor nestas condições, 1,27 x 10-5, bem como as perdas de solo de 0,59 t ha-1. Isto demonstra a importância da vegetação e da cobertura vegetal na proteção do solo no semiárido.Submitted by Mario BC (mario@bc.ufrpe.br) on 2016-08-16T12:30:56Z No. of bitstreams: 1 Cristina dos Santos Ribeiro Martins.pdf: 2325793 bytes, checksum: 1fa94be1a8b8e19da22fc4ca0ab09c2b (MD5)Made available in DSpace on 2016-08-16T12:30:57Z (GMT).
