Produção de água e sedimentos em bacia representativa do semiárido pernambucano

Abstract: R ESU M OA erosão hídrica é um dos principais processos responsáveis pela degradação física dos solos, em particular em áreas semiáridas, susceptíveis a chuvas de alta intensidade e com limitada cobertura vegetal, principalmente nos períodos secos. O presente trabalho teve como objetivo avaliar experimentalmente as características hidrossedimentológicas da bacia hidrográfica do Riacho Mimoso, no semiárido pernambucano, no município de Pesqueira, PE. A bacia representativa do Riacho Mimoso apresentou respostas … Show more

“…The land-use map was drawn based on images from the RapidEye satellite from April 2013, from the REHIDRO project (Lima et al, 2014). Land use was divided into six different classifications ( Figure 2A): Agriculture, Gallery Forest, arborescent closed Caatinga, arborescent-shrubby closed Caatinga, arborescent-open Caatinga and Bams (Silva Junior et al, 2011). The soil-types map was based on soil mapping carried out by EMBRAPA-Soils, from information provided by the Agroecological Zoning of Pernambuco (ZAPE) (EMBRAPA, 2000), identifying three predominant soil types: red-yellow Clay soil, Litolic Neosoil and Regolitic Neosoil ( Figure 2D).…”

“…Due to its characteristics, the Network of Hydrology of the Semiarid Region (REHISA) has been monitoring and conducting different studies around the basin area. The years 2009 and 2010 presented high precipitation in the region, with flow generation in the Alto Ipanema Basin (Silva Junior et al, 2011), in which the BERJ is inserted. In the last six years, the Alto Ipanema Basin (a tributary of the São Francisco River) had very little rainfall, which significantly reduced surface runoff generation.…”

“…This behavior, however, is responsible for the significant reduction in sediment load in rivers that have dams (SYVITSKI & KETTNER, 2011). The temporal variation of sediment production in watersheds in the short term is also related to rainfall patterns, as observed by SILVA JUNIOR et al (2011).…”

“…O ICMS Ecológico que beneficia municípios com áreas protegidas e mananciais de abastecimento público em todo Brasil permitiu que as áreas conservadas passassem a ser geradoras de recursos para os municípios, também é uma iniciativa de PSA . No Semiárido, diversos estudos apontam a necessidade de adoção de práticas conservacionistas para as diferentes bacias hidrográficas presentes na região (Araújo et al, 2009;Silva e Santo, 2009;Silva Jr et al, 2011). Assim, a adoção de projetos semelhantes como os citados acima serão de grande importância para o desenvolvimento sustentável, proporcionando uma oportunidade de aumentar a capacidade adaptativa da sociedade e da economia regional.…”
