Resumo: | The objective of this work was to evaluated the precipitation characteristics (depth, I30 and erosivity) and their effects on sediment production in three watersheds under different managements of land use 35-year regenerating Caatinga (RC), thinned Caatinga (TC), which underwent thinning of trees with diameter smaller than 10 cm; and deforested Caatinga (followed by burning and pasture) (DC). The experimente was conducted in the central, tropical semiarid region of the State of Ceará, Brazil. The precipitation events, surface runoff and sediment production were monitored from 2010 to 2015. The precipitation characteristics were subjected to Pearson's correlation at 1 and 5% of significance and the events that produced sediments in each watershed were hierarchically grouped by hierarchical cluster analysis technique. Two hundred precipitation events were recorded, with 23 (RC), 18 (TC) and 43 (DC) events producing sediments. The use of thinning (TC) decreased the sediment production by 53.5%, while the deforestation, burn and pasture cultivation (DC) increased soil losses by 14%, compared with the RC. The sediment production was greatly correlated with the I30 in the three watersheds, denoting the erosion process great dependence on the precipitation intensity. |

A área de estudo é representative de região semiárida tropical e está localizada na parte central do estado do Ceará. Foram monitorados eventos puviométricos, escoamento superficial e produção de sedimentosdos anos de 2010 a 2015. As características das chuvas foram submetidas a correlação de Pearson a nível de 1 e 5 % de significância e os eventos que produziram sedimentos em cada microbacia foram agrupados hierarquicamente pela técnica de Análise de Agrupamento Hierárquico. Ao todo foram registrados 200 eventos pluviométricos dos quais 23, 18 e 43 eventos produziram sedimentos nas microbacias CER, CRA e DQP respectivamente. A adoção do manejos de raleamento reduziu a produção de sedimentos em 53,5 %, enquanto que o DQP promoveu um aumento das perdas de solo em 14 % em relação à CER. A produção de sedimentos expressou uma maior correlação com o I30 para as três microbacias expressando a maior dependência do processo erosive da intensidade das chuvas.Universidade Federal Rural do Semi-Árido2017-01-24info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/590910.1590/1983-21252017v30n222rcREVISTA CAATINGA; Vol. 30 No. 2 (2017); 468-478Revista Caatinga; v. 30 n. 2 (2017); 468-4781983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/5909/pdfRibeiro Filho, Jacques CarvalhoPalácio, Helba Araújo de QueirozAndrade, Eunice Maia deSantos, Júlio César Neves dosBrasil, José Bandeirainfo:eu-repo/semantics/openAccess2023-07-20T10:57:48Zoai:ojs.periodicos.ufersa.edu.br:article/5909Revistahttps://periodicos.ufersa.edu.br/index.php/caatinga/indexPUBhttps://periodicos.ufersa.edu.br/index.php/caatinga/oaipatricio@ufersa.edu.br|| caatinga@ufersa.edu.br1983-21250100-316Xopendoar:2024-04-29T09:46:25.307105Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true |
