Resumo: The purpose of the present study is to calculate the averages maximum intensities of rainfall by means of determination of parameters of mathematical equation which relates the fundamental characteristics: intensity, (in mm/hour) duration (in minutes) and return period (in years). To generate basic information to engeneering and hydrological studies is the aim, mainly for soil conservation projects. Through the adjustment of mathematical equations using linear regression, the rainfall characteristics of eighty meteorological stations throughout the country were calculated. To determine the best adjustment, the maximum coefficient of multiple determination was used. The parameters for each site, its geographic characteristics (latitude and longitude), as well as the period of observation and the coefficient of multiple determination are presented.

Foram relacionadas as características da chuva de um total de oitenta estações climatológicas, distribuídas por todo o País, através do ajustamento de equações matemáticas pelo método de regressão múltipla linear. Para a determinação do melhor ajustamento, adotou-se o critério do máximo coeficiente de determinação múltipla. São apresentados os parâmetros obtidos para cada local, suas características geográficas (longitude, latitude e altitude), período de observação (em anos) e os coeficientes de determinação múltipla.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraDenardin, José EloirFreitas, Pedro Luiz de2014-04-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/16306Pesquisa Agropecuaria Brasileira; v.17, n.10, out. 1982; 1409-1416Pesquisa Agropecuária Brasileira; v.17, n.10, out. 1982; 1409-14161678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporenghttps://seer.sct.embrapa.br/index.php/pab/article/view/16306/10506https://seer.sct.embrapa.br/index.php/pab/article/view/16306/10507info:eu-repo/semantics/openAccess2014-04-15T19:48:10Zoai:ojs.seer.sct.embrapa.br:article/16306Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-15T19:48:10Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
