Modeling of Unsteady Flow through the Canals by Semiexact Method
Modelling and Simulation in Engineering, 2014 The study of free-surface and pressurized water flows in channels has many interesting application, one of the most important being the modeling of the phenomena in the area of natural water systems (rivers, estuaries) as well as in that of man-made ...

Coupling Green-Ampt and Saint-Venant Equations for Estimating of Transmission Losses during Flood Routing in Rivers [PDF]
علوم و مهندسی آبیاری, 2016 Volume of flooding flow volume in ephemeral streams decreases due to evaporation as well as the channel wall and bed penetration. This process is known as transmission losses.

Multilayer Saint-Venant equations over movable beds
Discrete and Continuous Dynamical Systems - B, 2011 We introduce a multilayer model to solve three-dimensional sediment transport by wind-driven shallow water flows. The proposed multilayer model avoids the expensive Navier-Stokes equations and captures stratified horizontal flow velocities. Forcing terms are included in the system to model momentum exchanges between the considered layers.

A Momentum-Conserving Scheme for Flow Simulation in 1D Channel with Obstacle and Contraction
Fluids, 2021 We consider the extension of the momentum conservative staggered-grid (MCS) scheme for flow simulation in channels with varying depth and width. The scheme is formulated using the conservative properties of the Saint-Venant equations. The proposed scheme

Consistent initial conditions for the Saint-Venant equations in river network modeling [PDF]
Hydrology and Earth System Sciences, 2017 Initial conditions for flows and depths (cross-sectional areas) throughout a river network are required for any time-marching (unsteady) solution of the one-dimensional (1-D) hydrodynamic Saint-Venant equations.
