TwoLe: a software tool for planning and management of water reservoir networks

A software tool, which implements a Decision Support System (DSS) for management of water reservoirs, is presented. It is designed to be used both at the planning level, by water agencies, to generate management policies and release plans over various time horizons, and at the management level, by the decision makers, to take daily release decisions, also using the real-time information provided by a telemetering network. The DSS algorithm presents multiple choices to the decision makers, helping them in assessing their impact, thus integrating, not substituting, human intelligence. The DSS architecture relies on a Model Management System (MMS) to allow a rapid prototyping of various modelling situations, both at the planning level and at the management level, while the graphical user interface is aimed at enforcing this structure.
