Resumo: Abstract- The rainfall erosivity factor can be estimated by the analysis of long series of pluviograph data or, alternatively, by the use of pluviometric methods. The objective of this work was to adjust the equations for the estimation of erosivity by the pluviometric method and to determine the temporal distribution pattern of the rainfall of Porto Union, as well as to determine the erosivity factor for the Northern Plateau Region of Santa Catarina. The Porto Union pluviograms of the period from 1973 to 1992 were analyzed, determining erosivity by the index EI30 and adjusting the equations to estimate this index by the pluviometric method. Based on the rainfall averages from 1984 to 2015 of ten stations located in the Northern Plateau of Santa Catarina, the erosivity factor (R) was estimated for the region. The most frequent erosive rains are of the Advanced pattern (54.5%), followed by Intermediate (32.3%) and Late (13.2%), respectively. The mean annual erosivity in the North Plateau ranged from 5,885 to 6,822 MJ mm ha-1 h-1 year-1, being classified as High erosivity.

Este trabalho teve por objetivos ajustar as equações para estimativa da erosividade pelo método pluviométrico e determinar o padrão de distribuição temporal das chuvas de Porto União, bem como determinar o fator erosividade para a Região do Planalto Norte de Santa Catarina. Foram analisados os pluviogramas de Porto União do período de 1973 a 1992, determinando-se a erosividade pelo índice EI30 e ajustadas as equações para estimativa desse índice pelo método pluviométrico. Com base nas médias pluviométricas do período de 1984 a 2015 de dez estações localizadas no Planalto Norte de Santa Catarina, estimou-se o fator erosividade (R) para a região. As chuvas erosivas mais frequentes são do padrão Avançado (54,5%), seguido respectivamente pelos padrões Intermediário (32,3%) e Atrasado (13,2%). A erosividade média anual no Planalto Norte variou de 5.885 a 6.822 MJ mm ha-1 h-1 ano-1, sendo classificada como erosividade Alta.  Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina - Epagri2018-03-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionquantitativoapplication/pdfhttps://publicacoes.epagri.sc.gov.br/rac/article/view/116Agropecuária Catarinense Journal; Vol. 31 No. 1 (2018); 61-66Agropecuária Catarinense; v. 31 n. 1 (2018); 61-662525-60760103-0779reponame:Agropecuária Catarinense (Online)instname:Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina (Epagri)instacron:EPAGRIporhttps://publicacoes.epagri.sc.gov.br/rac/article/view/116/214Copyright (c) 2018 Revista Agropecuária Catarinensehttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessBack, Álvaro José2018-06-07T17:04:51Zoai:ojs.publicacoes.epagri.sc.gov.br:article/116Revistahttps://publicacoes.epagri.sc.gov.br/RAC/indexPUBhttps://publicacoes.epagri.sc.gov.br/index.php/RAC/oaieditoriarac@epagri.sc.gov.br || lamperuch@epagri.sc.gov.br2525-60760103-0779opendoar:2018-06-07T17:04:51Agropecuária Catarinense (Online) - Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina (Epagri)false
