Statistical Roughness Properties of the Bed Surface in Braided Rivers

Braided rivers are widespread in nature, and their bed morphology is complex variable. This paper aims to investigate quantitatively analyze the surface roughness of braided utilizing statistical theory. In this paper, a physical model developed, four constant discharge experiments carried out. Based on Structure-from-Motion photogrammetry direct measurement bedload transport using load cell, data rate, morphology, elevation obtained, facilitating in-depth investigation correlations between these parameters. The results show that morphological active width increases with increasing discharge. There was significant positive correlation although there considerable scatter due inherent variability river morphodynamics. probability distribution surfaces shows negative skewness leptokurtic distribution. relatively dimensionless rate. two-dimensional variogram values variable, anisotropic. Additionally, both longitudinal sill length exhibit an increase rise stream power. Remarkably, length, as well proves be highly significant. Consequently, can serve reliable general factor for predicting rate reach.
