14. ABSTRACTDroughts are caused by both hydrologic and socioeconomic components. This document concentrates on stochastic modelsof streamflow as the hydrologic component of drought. Stochastic models of drought are presented to the water resource
engineer as an extension of the more commonly understood flood frequency analysis. The extension can be made because
flood frequency analysis utilizes stochastic models of independent random variables whereas drought analysis utilizesstochastic models of dependent random variables. There are many different stochastic models that have been implemented
to describe dependent random variables. A comparison of these models indicates that simple ones, such as the
autoregressive model, are adequate for the water resource engineer's needs.
