Resumo: | The hydroelectric power plants (HPP) in Ilha Solteira and Jupiá are part of the Urubupungá Hydroelectric Complex, which is the sixth most important hydroelectric complex in the world. However, their reservoirs are undergoing an intense siltation process. We evaluated the erosive potential of the Santa Vera Stream Watershed (SVSW), located on the banks of the Jupiá HPP reservoir. Soil use and occupation maps, and field analysis, enhanced by Geographic Information Systems (GIS), were used to obtain important parameters for the creation of RUSLE factors for the entire watershed. It was confirmed that areas dominated by degraded pastures that lacked conservation practices, such as contour lines, together with the increase in steepness of slopes toward areas near the drainage networks, resulted in higher estimates of soil loss. We concluded that the predominant values for soil loss estimates in the SVSW were low or close to zero. Nevertheless, values classified as being above soil recovery capacity were found in the reservoir banks, which lack riparian vegetation. Therefore, projects aiming at replenishing the vegetation of the reservoir banks are extremely important for their maintenance and for the conservation of native species in the region. |

Neste contexto, estre trabalho tem como objetivo avaliar o potencial erosivo da Bacia Hidrográfica Córrego Santa Vera (BCSV), localizada as margens do reservatório da UHE de Jupiá. Por meio do uso de mapas de uso e ocupação dos solos e análises de campo, associada à utilização de Sistemas de Informações Geográficas (SIGs) pôde-se obter parâmetros importantes para a confecção dos fatores pertencentes a RUSLE para toda bacia. Verificou-se a predominância de áreas com pastagens degradadas e sem uso de boas práticas conservacionistas, como curvas de nível, que associados ao aumento da declividade nas áreas próximas as redes de drenagem, resultaram em maiores estimativas de perdas de solo. Concluiu-se que os valores predominantes de estimativa de perda de solo na BCSV foram baixos ou próximos de zero, porém, valores classificados como acima da capacidade de recuperação do solo foram encontrados nas margens do reservatório, que não possuem mata ciliar. Neste âmbito, projetos que visem a revegetação das margens do reservatório são de extrema importância para a manutenção do reservatório bem como a conservação de espécies nativas da região.UNESPDigitUMaMartins, Fernando PavaninMacedo, Fabrício Lopes deSilva, Helio RicardoGrance, Samuel FernandesLucena, Luiz Augusto de2024-01-03T14:28:11Z20212021-01-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttp://hdl.handle.net/10400.13/5456porMartins, F.
