Outline of Final Research Achievements

Steady state of sand bars have understood that channel width decieds as either single row bar or central bar. A characteristics of single row bar has known well according to many pas studies. However past studies have not provided much elucidation on basic characteristics of central bars, we can not give enough explanation that central bars in natural rivers has formed for a long time. In this study, we found that central bars in natural river have kept commonly to be formed in longitudinal variable width. Also side wall of channel plays a very important role on formation process of sand bars.
