Abstract: The approaches for studying channel pattern used by various investigators have been classi-fied according to their theoretical basis in this paper, such as hypothesis on geomorphic thre-sholds, extremal hypothesis on energy dissipation rate, theory of stability, theory of stochastic analysis and method of statistic analysis.

Key words: River pattern, Threshold, Extremal value, Stability
