Resumo: Mean values of monthly and annual level of Paraguay River in Ladário County (1900/1995) were studied by several numerical methods which include: Fourier analysis, periodogram, dynamic spectral analysis and iterative regression. This work intended to identify the main characteristics of the river flow and to use the main periodicities embedded in the series to evidence possible causes or factors which may influence its variations. The river flow is not stationary; however, an attempt was done to use only the eight main periods to predict the river behavior at a time scale of a few decades.

A finalidade do trabalho é identificar as grandes características do regime do rio e, através das principais periodicidades embutidas na série, as possíveis causas ou os fatores que podem intervir em suas variações. O regime do rio não é estacionário, porém, tentou-se utilizar apenas as oito periodicidades maiores para prever o comportamento do rio numa escala de tempo de algumas décadas.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraNordemann, Daniel Jean Roger1998-12-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/5060Pesquisa Agropecuaria Brasileira; v.33, n. especial, out. 1998; 1787-1790Pesquisa Agropecuária Brasileira; v.33, n. especial, out. 1998; 1787-17901678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/5060/7215info:eu-repo/semantics/openAccess2011-08-29T13:27:26Zoai:ojs.seer.sct.embrapa.br:article/5060Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2011-08-29T13:27:26Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
