Summary: | The fundamental characteristics of rainfall (intensity, duration and return period) of fourteen locations were related through the adjustment of mathematical equations, aiming at to generate representative precipitation data for each location as well as to intensity its use in soil conservation projects. Each equation, expressing the rainfall intensity as a. function of return period and duration, was adjusted using the multiple linear regression method. To determine the best adjustment, the maximum coefficient of multiple determination was used. The adjustments showed to be in agreement with field data. The F value for the regression were significant at 1% level of probability. The regression coefficients, determined for the adjustments, showed a great variability for the values of rainfall intensity from one location to another, what makes impossible a generalization of only one equation for the entire state. |

Cada equação, expressando a intensidade da precipitação em função do tempo de retorno e tempo de duração, foi ajustada pelo método de regressão múltipla linear. Para a determinação do melhor ajustamento, adotou-se o critério do máximo coeficiente de determinação múltipla. Os ajustamentos alcançaram um elevado grau de correlação com os dados de campo, sendo, os valores de F para regressão, significativos ao nível de 1% de probabilidade. Os coeficientes de regressão determinados pelos ajustamentos evidenciaram uma grande variabilidade nos valores de intensidade da chuva de uma localidade para outra, impossibilitando, assim, a generalização de uma única equação para todo o estado.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraDenardin, José EloirFreitas, Pedro Luiz deWunsche, Werner ArnaldoWendt, Wilmar2014-04-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/16602Pesquisa Agropecuaria Brasileira; v.15, n.4, abr. 1980; 419-421Pesquisa Agropecuária Brasileira; v.15, n.4, abr. 1980; 419-4211678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/16602/10890info:eu-repo/semantics/openAccess2014-04-15T19:35:38Zoai:ojs.seer.sct.embrapa.br:article/16602Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-15T19:35:38Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
