In this study, different methods of long-term morphological modeling are briefly reviewed. These methods include input reduction, schematization of flow perturbation induced by bed changes and increase of the morphological time step. In the discussion of schematization, methods like tide-averaging, continuity correction, RAM, online or morphological factor and MORFAC, are presented. In the next discussion, the morphological time step, four methods namely straightforward extrapolation, time-centered extrapolation, lengthening of the tide and extrapolation of sediment transport as a function of bed evolution are discussed. As a conclusion it can be postulated that RAM method and time-centered extrapolation are best methods among the rest.
Key words: Bed change, estuary, extrapolation, input reduction, tide, wave,
