Abstract: As a prevalent phenomenon, there are many streambed structures in rivers. The distribution of them was obviously in certain orders. This paper carried out numerical analysis and field work in natural rivers, to study the law of streambed structures’distribution. The results indicated that: A river profile with streambed structures can be considered as an overlay of two parts: an average longitudinal streambed line which reflect the total slope-trend; and a wave-shape line vibrating along this average streambed line which reflect the effect of streambed structures. The two parts were then distinctively separated by the frequency analysis. Then the distribution of streambed structures can be calculated and analyzed more scientifically.
