A new type of diagnostic test based on the generalized variance is discussed. The purpose of this diagnostic check is to test the assumption of statistical independence of the error terms or innovations in these models. Most of the theoretical component of this work has been accepted for publication in the Journal of Time Series Analysis. We will focus on hydrological extensions and applications to multisite and multivariate riverflow. Simulation of daily flow using wavelet methods will also be discussed.

Keywords: Multivariate; Diagnostic check; Monte Carlo test; Wavelets
