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.

Numerical study of the applicability of the Saint-Venant principle

MATEC Web of Conferences, 2017
The limits of the applicability of the Saint-Venant principle are investigated while using the LIRA-CAD app. A large number of bars loaded at the end with different loads are considered.

Gravel Replenishment Downstream of Dams: Insights From a Flume Experiment in a Straight Embanked Channel

Water Resources Research
Gravel replenishment (GR) is a common strategy to mitigate the negative effects of sediment deficit caused by dam regulation. However, its effectiveness in restoring dam‐regulated embanked gravel‐bed rivers with alternate bars is still unclear.

Experimental and smoothed particle hydrodynamics‐finite element method simulation investigation of synergistic erosion mechanism of gangue‐based abrasive water jets

Deep Underground Science and Engineering, EarlyView.
This study proposes an eco‐friendly coal permeability enhancement technique by utilizing mine waste gangue as an abrasive in high‐pressure water jets. Integrating erosion experiments with smoothed particle hydrodynamics‐finite element method coupled simulations, the research study elucidates the flow field dynamics and a nonlinear solid–liquid ...
