             abstract = "The present paper analyzed the relationship between streamflow and 
                         rainfall at the stream of Itapemirim River Watershed (BHRI). The 
                         minimum streamflow with duration of seven days (Q7), the average 
                         annual streamflow (Qmed) and the annual maximum streamflow (Qmax) 
                         of 11 BHRIs sub-basins were determined. Trends in rainfall and 
                         streamflow series were analyzed with Mann-Kandall and Pettitt 
                         nonparametric tests. Regression analysis between rainfall and 
                         streamflow were established. Results showed no trends on rainfall 
                         and Q7 series. Trends in Qmed were found only at one sub-basin and 
                         trends in Qmax were found in two sub-basins. The total rainfall 
                         was correlated with the streamflow of all the sub-basins. It has 
                         been found that annual rainfall amount (Pa) explained considerably 
                         variations in Qmed and Q7. Rainfall amounts of the rainiest month 
                         (Pmax) showed good correlation to Qmax. RESUMO: 
                         Rela{\c{c}}{\~a}o entre as vaz{\~o}es e as 
                         precipita{\c{c}}{\~o}es na bacia hidrogr{\'a}fica do rio 
                         Itapemirim. O presente trabalho teve por objetivo analisar a 
                         rela{\c{c}}{\~a}o entre as vaz{\~o}es de cursos d{\'a}guas da 
                         bacia hidrogr{\'a}fica do rio Itapemirim (BHRI) e a 
                         precipita{\c{c}}{\~a}o pluviom{\'e}trica. Determinaram-se, para 
                         as 11 sub-bacias da BHRI, a vaz{\~a}o m{\'{\i}}nima m{\'e}dia 
                         com sete dias de dura{\c{c}}{\~a}o (Q7), a vaz{\~a}o m{\'e}dia 
                         anual (Qmed) e a vaz{\~a}o m{\'a}xima anual (Qmax). A fim de 
                         verificar a ocorr{\^e}ncia de tend{\^e}ncias significativas e/ou 
                         mudan{\c{c}}as bruscas nas s{\'e}ries de vaz{\~a}o e 
                         precipita{\c{c}}{\~a}o, aplicaram-se os testes de Mann-Kendall e 
                         de Pettitt. Para a an{\'a}lise da rela{\c{c}}{\~a}o entre 
                         chuvas e vaz{\~o}es foram realizadas an{\'a}lises de 
                         regress{\~a}o. Com rela{\c{c}}{\~a}o {\`a}s tend{\^e}ncias, 
                         os resultados mostram que as precipita{\c{c}}{\~o}es e a Q7 se 
                         mostraram estacion{\'a}rias em todas as sub-bacias. A Qmed 
                         n{\~a}o foi estacion{\'a}ria apenas em uma e a Qmax em duas das 
                         subbacias. O total precipitado possui forte correla{\c{c}}{\~a}o 
                         com as vaz{\~o}es das sub-bacias estudadas. Verificou-se que as 
                         chuvas anuais (Pa) atuaram de forma consider{\'a}vel para as 
                         varia{\c{c}}{\~o}es das Qmed e Q7. As chuvas do m{\^e}s mais 
                         chuvoso (Pmax) mostraram boa correla{\c{c}}{\~a}o com a Qmax.",
