The nonlinear prediction problem in the study of the runoff cycle

摘要: The general theory of nonlinear synthesis and analysis in hydrology is discussed, with particular reference to the problems predictive uncertainty. These are associated incomplete descriptions hydrologic systems, limited model-prototype equivalences, system variability time, nonlinearity. Solutions problem systems under assumption approximate time invariance, based on complex cascade network approximations, power series polynomial expansions, variable response function approximations presented. relations between present theoretical knowledge its practical application summarized.
