BED FORMS IN STEEP CHANNELS WITH HETEROGENEOUS BED MATERIALS INDUCED BY BOTTOM ELEVATION INSTABILITY AND SORTING INSTABILITY

Linear stability analyses for steep channel flows with movable bed of heterogeneous materials following a Talbot grain size distribution were performed in order to investigate peculiar characteristics of the bed forms.It was found that two kind of instability exist in the system such that one would...
