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.

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

Simulation of complex free surface flows [PDF]
ESAIM: Proceedings and Surveys, 2021 We study the Serre-Green-Naghdi system under a non-hydrostatic formulation, modelling incompressible free surface flows in shallow water regimes. This system, unlike the well-known (nonlinear) Saint-Venant equations, takes into account the effects of the
