Within the framework of the project entitled "Modernization of the supervision and management of the water resources for water supply of Athens", an operational system was developed for the stochastic simulation and forecast of hydrologic variables. More specifically, an original two-level multivariate scheme was introduced, appropriate for preserving the most important statistics of the historical time series and reproducing characteristic peculiarities of hydrologic processes such as persistence, periodicity and skewness. The mathematical model was implemented in a computer package, named Castalia, and it was applied for the generation of synthetic hydrologic time series within the simulation models the are components of the decision support system for the management of the Athens water supply system.
