Research Abstract

Autostratigraphy of shelf deltas growing under intense sediment dispersion has been explored by means of model experiments. The following particular notions are noteworthy.(1) Even in an open shelf setting where sediment is intensely dispersed but is not removed far away from the coastal system, large-scale deterministic autogenesis inherent to river deltas can go functionally. (2) There exists conspicuous synchronism between periodical recession of hydraulic jumps and discrete cyclic sedimentation of delta foreset. The action of coastal waves functions to bring distinct bedding. (3) The ratio of sediment supply rate to water supply rate controls a long-term pattern of channel avulsion and thereby shoreline configuration too.
