Abstract: Abstract Many applications in the field of environmental simulation are not limited to the dynamics of one-dimensional inventory variables, but additionally try to describe the spatial dimension of the investigated objects with their dynamic changes. The paper is based on a general specification level for such topological changes of geo-objects using graph replacement systems and shows how such a specification can be integrated transparently and consistently as an extension of the basic algorithm for combined, discrete–continuous models. The topological events are analysed in their semantics and their treatment is presented as an additional, modular algorithm part. Problems caused by this kind of specification and processing are uniqueness problems when several events occur simultaneously as well as the stability of the model specification in case of event cascades. Both problem areas are discussed with regard to their importance for the semantics of the model specification and the interpretation of the simulation results.
