Wavelet Analysis on the Distribution of the Streambed Forms

Abstract:

As a prevalent phenomenon, there are many streambed forms 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 forms' distribution. The results indicated that: A streambed profile can be considered as an overlay of two parts: the average streambed line which reflect the total slope (called 'Trend part'); the wave line vibrating along this average streambed line which reflect the effect of bed forms (called 'Form part'). The two parts were then distinctively separated by the wavelet analysis. Then the distribution of bed forms can be calculated and analyzed more scientifically.
