New Method for Estimating Roughness Coefficient for Debris Flows

Flow resistance is a fundamental control of flow hydraulics in streams and rivers. In this paper, five dimensionless factors affecting the Manning roughness coefficient <i>n</i> and attributed to the external roughness coefficient <i>n</i><sub>1</sub> and the inte...
