Resumo: Mechanical practices or hydraulic works are part of the principles of the conservationist management of soil and are tailored depending on several factors, among them the characteristics of the local rainfall. This work aims to analyze the data of heavy rain to support the dimensioning of soil conservation projects in the region of Chapecó, Santa Catarina. The historical series data of daily precipitation obtained in Chapecó rainfall station was used. The parameters of the Gumbel-Chow distribution were adjusted based on the historical series of maximum annual rainfall for the period from 1973 to 2016. From the breakdown of the maximum daily rainfall, the intense rainfall equation was adjusted. It was noted that there is a higher frequency of extreme rainfall events in autumn and a lower one during summer. The maximum daily rainfall, with a return period of 10 years, to be adopted as a criterion for level terracing dimensioning was 146.9mm. For drainage terraces, the maximum rainfall intensity lasting 15 minutes and with a return period of 10 years was assumed to be 141.9mm h-1.

Nesse sentido, este trabalho buscou analisar os dados de chuva intensa visando subsidiar o dimensionamento de projetos de conservação do solo na região de Chapecó, SC. Utilizou-se como base a série histórica de precipitação diária obtida na Estação Pluviométrica de Chapecó. Foram ajustados os parâmetros da distribuição de Gumbel-Chow com base na série histórica de chuvas máximas anuais, para o período de 1973 a 2016. A partir da desagregação das chuvas máximas diárias, procedeu-se o ajuste da equação de chuvas intensas. Observou-se que há maior frequência de eventos extremos de chuva no outono e menor no verão. A chuva máxima diária, com período de retorno de 10 anos, a ser adotada como critério para o dimensionamento de terraços em nível foi 146,9 mm. Já para terraços de drenagem, a intensidade da chuva máxima com duração de 15 minutos e período de retorno de 10 anos, assumida foi de 141,9 mm h-1Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina - Epagri2019-10-03info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://publicacoes.epagri.sc.gov.br/rac/article/view/49610.22491/RAC.2019.v32n3.14Agropecuária Catarinense Journal; Vol. 32 No. 3 (2019); 95-100Agropecuária Catarinense; v. 32 n. 3 (2019); 95-1002525-60760103-0779reponame: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/496/457Copyright (c) 2019 Revista Agropecuária Catarinenseinfo:eu-repo/semantics/openAccessBack, Álvaro JoséWildner, Leandro do PradoGarcez, Juliano Gonçalves2020-04-28T21:40:08Zoai:ojs.publicacoes.epagri.sc.gov.br:article/496Revistahttps://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:2020-04-28T21:40:08Agropecuária Catarinense (Online) - Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina (Epagri)false
