Modeling two-dimensional erosion process over infiltrating surfaces
(American Society of Civil Engineers, 2001-05)
The physics-based modeling of the rainfall-runoff induced erosion process is accomplished. The existing one-dimensional erosion process equations are extended to two dimensions and kinematic wave approximation is used. The ...
Numerical modeling of transport processes at hillslope scale accounting for local physical features
(Nova Science Publishers, 2011-01-01)
Hillslope is the basic unit of a watershed. Typical hillslopes may have a size of 1000 m long and 500 m wide. For watershed modeling, it is essential to accurately describe the illslope-scale processes of flow, erosion and ...
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 ...
Modeling pollutant transport in overland flow over non-planar and non-homogenous infiltrating surfaces
(Zhejiang University Press, 2013-02)
Pollutant transport in overland flow over surfaces with spatially varying microtopography, roughness, and infiltration was investigated using the diffusion wave equation and transport rate-based equation. The finite volume ...
