Abstract: Scenario approach is widely used in numerical modeling for the assessment of current and prospective states of environmental and ecological systems. The results of modeling essentially depend on the representation of the underlying hydrodynamics. We suggest a methodology for a quantitative description of the behavior of a dynamic system for a long time interval in a compressed, generalized form. Following it, the necessary information, intended to be used for the construction of scenarios, is extracted from a database containing measured and/or calculated data on hydrodynamic state functions.
