Computer Simulation of Underwater Sediment Transport

Abstract

The objective of the present investigation is to quantify the sedimentological and fluid-flow conditions necessary for the development of nearshore morphology and to determine the origin of the spacing or scale of selected bedform patterns. This study is motivated by the possibility that nearshore morphology is self-organized, meaning that local sediment-sediment or sediment-fluid interactions lead to the observed regular patterns without a global (fluid-flow) pattern imposed on the sand bed. Recently, self-organized models of arid landforms including wind ripples and sorted stone stripes have been proposed.Therefore, a related objective is testing the hypothesis of self- organization against hydrodynamical models for nearshore morphological pattern developement. The two patterns of primary focus are rolling grain ripples and beach cusps.
