Os modelos bivariados tem sido utilizados com sucesso na análise de processos hidrológicos. Neste trabalho, são deduzidas as distribuições exatas das variáveis U = X + Y, P = XY e Q = X/(X + Y) juntamente com seus respectivos momentos quando X e Y seguem o modelo bivariado gama beta II. Essas funções descrevem importantes variáveis hidrológicas. Os resultados obtidos são aplicados em dados de precipitações pluviométricas ocorridasna cidade de Passo Fundo - RS.
