沙波当量粗糙度的分形特性初探
Preliminary Study on the Fractal Properties of Bedform Equivalent Roughness
摘要
Abstract
Fractal dimensions were used to descript the bedform’s irregularity and complexity,based on immovable bed experimental investigations, the fractal expression of bedform equivalent roughness was developed,and the relation between non-dimensional equivalent roughness,fractal dimen-sion and relative height were obtained. Finally,the fractal expression was compared by some representative formulas,along with the disscusion to it. The results indicate that the expression can better reflect the influence of bedform’s three-dimensional characteristics to the equivalent roughness.关键词
