Fluvial dynamic landform is produced by reaction between fluvial bchaviour and suffoce matenal. It possesses apparent environmental effects. As a branch of gcomorphology, the fiuvial dynandc gcomorphology is a marginal science among fiuid dynalnics, sediment mechaltics and fluvial goomorphology. With physical modelling by sindlarity based on Newtonian mechanics, and pnnciple of the same effect bot diffend struCture based on systelnahc theory, it is possible to study propenies, formation and processes in fluvial dynamic gcomorphology. A new research method, which is a combination of mathematical simulation by computer with physical modelling will be deveoped.
