Numerical model for sediment transport over nonplanar, nonhomogeneous surfaces
(American Society of Civil Engineers, 2004-01)
Sediment transport on surfaces with spatially variable microtopography, roughness, and infiltration was investigated using the diffusion wave equation. An implicit finite-difference scheme together with multivariate Newton's ...
Kinematic wave model for transient bed profiles in alluvial channels under nonequilibrium conditions
(American Geophysical Union, 2007-12)
Transient bed profiles in alluvial channels are generally modeled using diffusion (or dynamic) waves and assuming equilibrium between detachment and deposition rates. Equilibrium sediment transport can be considerably ...
