Abstract

Vegetated flow in open channel is studied by many researchers. However, there are few studies about steep slope flows with vegetation. This study aims to predict turbulence property of this flow so as to estimate the degree of erosion at levees when flood flow occurs. Two models and two coefficients are used in this study. There are significantly different results due to the difference of coefficients which is not optimized from those which is optimized. Therefore, it is important to optimize coefficients to be applied. The prediction of turbulence property was improved by optimized coefficients in this study.
