Reservoirs / Eruptible volumes synthesis: BN model branches—see text for keys to node titles. As with Figs. 2 and 3, above, each node holds a statistical probability density function (PDF) expressing the variable uncertainty and arrows denote conditional uncertainty dependencies between nodes (i.e., ‘parent–child’ links). During development of a BN model, legacy PDFs from earlier runs can be retained in the UNINET data file and are available for sensitivity testing and for exploring the impacts of weighted alternates
