Vegetation-Induced Drag: An Experimental Study
Open-channel flow models through vegetative canopies require a quantitative measure of the ability of plants to absorb momentum by form drag, which is commonly characterized in terms of...

Optimal Sizing of Width- and Depth-Constrained Trapezoidal Channels
Open-channels are often designed based on the assumption of uniform flow and normal depth. If a channel is to be lined with a nonerodible material, the dimensions of the channel can be...

Chezy Formula Versus Theory and Common Sense
Using the theoretical concepts of the uniform flow formula and the inverse solution of the Chezy equation it is shown that a channel shape may have considerable influence on the value...

Roll Waves in Mud Flow
Permanent roll waves on a shallow layer of fluid mud which is modeled as a power-law fluid is studied. Based on long-wave approximation, momentum integral method is applied to derive the...

Granular Flow on a Bumpy Inclined Chute
Theoretical predictions for steady, uniform granular flows of identical, smooth, nearly elastic disks and spheres on bumpy inclined chutes are obtained. Kinetic constitutive theory is...
