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 ...

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 ...
Transient Two-Dimensional Simulation of Real Flood Events in a Mediterranean Floodplain
Publisher: American Society of Civil Engineers
Abstract: The application of a two-dimensional (2D) finite volume numerical model to real flood events in the Ebro River is presented. The hydraulic model used is based on the 2D transient shallow-water equations on the irregular ...
Fertigation in Furrows and Level Furrow Systems. I: Model Description and Numerical Tests
Publisher: American Society of Civil Engineers
Abstract: The simulation of fertigation in furrows and level furrow systems faces a number of problems resulting in relevant restrictions to its widespread application. In this paper, a simulation model is proposed that addresses ...
Fertigation in Furrows and Level Furrow Systems. II: Field Experiments, Model Calibration, and Practical Applications
Publisher: American Society of Civil Engineers
Abstract: Furrow fertigation can be an interesting practice when compared to traditional overland fertilizer application. In the first paper of this series, a model for furrow fertigation was presented. The simulation model combined ...
