Abstract
Drought problems must be analyzed and solved at a regional level. Drought studies must focus not only on the hydrological characterization of the phenomena but also formulate the results in terms of engineering risk. In this paper concepts and methods to characterize droughts as regional processes are presented. The concepts of risk, reliability, resiliency and vulnerability are applied to characterize regional droughts and provide an engineering framework to deal with drought problems. A Portuguese river basin (rio Ave) is used to illustrate the concepts and techniques presented in the paper. A multivariate stochastic model is used to generate a synthetic series of monthly precipitation at six distinct regions defined in the river basin. Thirty-three years of monthly data are used to calibrate the parameters of this model. The generated series is used to perform the study of regional droughts from an engineering risk point of view.
