The lifecycle of a glacier and its impact on natural and social environment depend on the interplay of factors provided by hydro-, atmo- and lithosphere. Quantitative models describing particular cases of this interplay rest on assumptions about the role of each factor. However, often these roles, being formalized and quantified, are not understood qualitatively well enough. This certainly undermines the quality of models proposed and impedes their comparison and management. The event bush allows to build an information model of the entire domain of knowledge about glacier evolution and bring existing (and even future) models and datasets into one information space.
