Radial Flow Modeling for Estimating Level-Basin Irrigation Parameters
Publisher: American Society of Civil Engineers
Abstract: Previous research in the estimation of surface irrigation parameters from advance time or surface profile observations has focused on the development of solutions for parallel surface flow conditions. This study was conducted ...
Numerical Modeling of Flood Propagation through System of Reservoirs
Publisher: American Society of Civil Engineers
Abstract: An explicit numerical flow‐routing model is developed based on the second order McCormack scheme. This paper describes the use of the finite difference scheme for the solution of the St. Venant equations of the one‐dimensional ...
2D Zero-Inertia Model for Solution of Overland Flow Problems in Flexible Meshes
Publisher: American Society of Civil Engineers
Abstract: A study of the efficiency of a zero-inertia model (ZI) for two-dimensional (2D) overland flow simulation is presented in this work. An upwind numerical scheme is used for the spatial discretization in the frame of finite-volume ...
One-Dimensional Riemann Solver Involving Variable Horizontal Density to Compute Unsteady Sediment Transport
Publisher: American Society of Civil Engineers
Abstract: Intense transient shallow flows over erodible bed imply the appearance of a changing horizontal density attributable to the presence of sediment particles in the water layer. The lack of consideration of the variability ...

Solute Transport Modeling in Overland Flow Applied to Fertigation
Publisher: American Society of Civil Engineers
Abstract: A model of solute transport in overland flow is developed and applied to the simulation of surface fertigation. Water flow is simulated using the depth-averaged, 1D shallow water equations. Solute flow is represented by ...
One-Dimensional Model of Shallow Water Surface Waves Generated by Landslides
Publisher: American Society of Civil Engineers
Abstract: A numerical model is presented as the basis for the study of surface waves generated by bank and bottom landslides in rivers. The flow is assumed to be properly modeled by the shallow water equations. The solid movement ...
Analysis of the Friction Term in the One-Dimensional Shallow-Water Model
Publisher: American Society of Civil Engineers
Abstract: The numerical simulation of unsteady open channel flows is very commonly performed using the one-dimensional shallow-water model. Friction is one of the relevant forces included in the momentum equation. In this work, a ...
Numerical Modeling of Basin Irrigation with an Upwind Scheme
Publisher: American Society of Civil Engineers
Abstract: In recent years, upwind techniques have been successfully applied in hydrology to simulate two-dimensional free surface flows. Basin irrigation is a surface irrigation system characterized by its potential to use water ...
