A kinetic interpretation of the section-averaged Saint-Venant system for natural river hydraulics.

, 2010
International audienceThe classical Saint-Venant system is well suited for the modeling of dam breaks, hydraulic jumps, reservoir emptying, flooding, etc.

On the assimilation of altimetric data in 1D Saint–Venant river flow models

Advances in Water Resources, 2018
Given altimetry measurements, the identification capability of time varying inflow discharge Qin(t) and the Strickler coefficient K (defined as a power-law in h the water depth) of the 1D river Saint-Venant model is investigated.

Dynamic response at the terminus of oblique intersecting joints subjected to stress waves

Deep Underground Science and Engineering, EarlyView.
This study derives the propagation equation for stress waves impinging upon nonlinear oblique intersecting joints. It analyzes the dynamic response at the terminus of nonlinear oblique intersecting joints subjected to stress waves. Abstract To investigate the dynamic response at the terminus of oblique intersecting joints subjected to stress waves, a ...

Well-balanced positivity preserving central-upwind scheme with a novel wet/dry reconstruction on triangular grids for the Saint-Venant system

Journal of Computational Physics, 2018
In this paper, we construct an improved well-balanced positivity preserving central-upwind scheme for the two-dimensional Saint-Venant system of shallow water equations. As in Bryson et al.

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.

Experiencing Extreme Hunger in Anorexia Nervosa Recovery: A Qualitative Analysis of Reddit Narratives

International Journal of Eating Disorders, EarlyView.
ABSTRACT Objective Recovery from anorexia nervosa involves psychological and social adjustments that extend beyond weight restoration. Online forums increasingly serve as spaces where recovery experiences are openly shared, including accounts of “extreme hunger” during refeeding—a phenomenon that has not been reported in the clinical literature.
