Resumo: | The objective of this work was to perform a statistical analysis of rainfall data gathered in Mococa, State of São Paulo, from 1970 to 1990, including the relationship between intensity, duration and frequency. The studied data were registered with a rain gauge located at the Experimental Station of the Instituto Agronômico, in Mococa, São Paulo State, Brazil. The relationship were studied for the following duration intervals: 5, 10, 15, 25, 30, 45, 60, 90, and 120 minutes. The Chow-Gumbel method was applied for the study of frequency distribution of intense precipitation for recurrency times of 5, 10, 25, 50, and 100 years. Also, the method of minimum squares was applied to obtain an equation for the same relationship. Final results showed good correlation between both methods, as well as with the maximum rainfall values obtained for each duration, resulting in linear regression coefficients of 0.9990 and 0.9920, respectively. Results indicated that the equation can be utilized for cases where values of maximum rainfall intensities are needed. |

Os dados analisados foram registrados com pluviógrafo instalado na estação experimental do Instituto Agronômico, em Mococa. Foram estudados os seguintes intervalos de duração: 5, 10, 15, 25, 30, 45, 60, 90 e 120 minutos. Para o estudo da freqüência de distribuição das chuvas intensas nos tempos de recorrência de 5, 10, 25, 50 e 100 anos, utilizou-se o método de Chow-Gumbel. Aplicou-se também o método dos mínimos quadrados para obter equação da mesma relação. Os resultados finais mostraram boa correlação entre os dois métodos, assim como os valores de intensidade máxima de chuva obtidos em cada duração, resultando nos coeficientes de regressão linear 0,9990 e 0,9920, respectivamente. Os resultados mostraram que a equação pode ser utilizada nos casos em que as intensidades máximas de chuva são necessárias.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraVieira, Dirceu BrasilNeto, Francisco LombardiSantos, Ronaldo P. dos1998-08-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/4953Pesquisa Agropecuaria Brasileira; v.33, n.8, ago. 1998; 1215-1220Pesquisa Agropecuária Brasileira; v.33, n.8, ago. 1998; 1215-12201678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/4953/7082info:eu-repo/semantics/openAccess2015-01-02T15:49:17Zoai:ojs.seer.sct.embrapa.br:article/4953Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2015-01-02T15:49:17Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
