In recent years, an increment of river engineering activities and more intensive use of flood plain, the river geomorphology has attracted considerable attention owing to an extensive land reclamation. One of the important problems is the maintenance of river meanders and almost all natural rivers exhibit the tendency to be a meander. A statistical analysis is applied to typifying their shapes and the meander characteristics are analyzed by channel model of line generalization algorithm in this study. This method is applied to Han River System. The results show that the variance of curvature is a better index to describe the meander intensity and the kurtosis is a good index to characterize the total lengh of the straight sections for a given reach. The channel model of line generalization algorithm gives good results in analysis of meander characteristics.
