This research takes in the interference between the modes of double-row bars and alternate bars to the weakly nonlinear analysis、 and aims at clarifying the degree of the interference between the modes. The view of the rate of linear amplification is newly introduced into this model so that the same order can examine alternate bars and double-row bars. Hydraulic conditions of this analysis were set large width-depth ratio in which double-row bars generated. The results of this analysis can not reproduce the results of hydraulic experiments quantitatively. However、 this analysis is shown that the qualitative characteristics of bar mode decrease process are reproducible. The result that neither of both modes (alternate bars and double-row bars ) could grow up was obtained.
