Abstract
Braided streams are deformed intricately with time and space and it is difficult to predict the future geometry of each streams. Of course, coexist of broad band scaled streams in a river reach causes the complex tempospacial change of streams. But bed unstability in a stream causes a stream deformation, too. It was discussed here that bed unstability at which area affects stream deformation strongly according to the results of numerical analysis. Furthermore, stability characteristics of streams was investigated using numerical analysis and the method how to use the information of predicted braided streams was suggested for river regulation works.
