Then the paper presents the reference schemes that are being used to define scenarios for both the environmental forcings and the possible changes in land use and socioeconomic conditions for the Po Delta area and having in mind both the definition of the medium and long term trends and changes in extremes.<P> Boundary conditions refers to modelling, and in particular to the needs to be satisfied by models that will be used in the framework of the MEDDELT project in order to quantitatively evaluate physical and ecological processes and qualitatively assess the role of anthropogenic factors.<P> The resulting framework hereby introduced allows for the definition of the boundary conditions and/or inputs which are needed for the computation of indicators and for the subsequent utilization of balance models which will be used to evaluate the deltaic behavior under the proposed scenarios.<P> The paper has the character of a discussion document and presents reference considerations and preliminary evaluations that, as such, are subject to change and adaptation.<P>
