A Finite-Volume discretization of viscoelastic Saint-Venant equations for FENE-P fluids

, 2017
International audienceSaint-Venant equations can be generalized to account for a viscoelastic rheology in shallow flows. A Finite-Volume discretization for the 1D Saint-Venant system generalized to Upper-Convected Maxwell (UCM) fluids was proposed in ...

Monolithic Framework to Simulate Fluid‐Structure Interaction Problems Using Geometric Volume‐of‐Fluid Method

International Journal for Numerical Methods in Fluids, Volume 98, Issue 10, Page 1105-1125, October 2026.
A three‐dimensional fluid‐structure interaction (FSI) framework is developed using the geometric volume‐of‐fluid (VOF) interface capturing method and applied to assess largescale turbulent FSI interactions. The monolithic FSI framework is extensively validated, and despite the discontinuities across the interface, the FSI framework delivers stable and ...

A Catchment‐Based Global Model of River Discharge and Flow Velocity for Earth System Models

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 10, October 2026.
Abstract The representation of river flows in Earth System Models (ESMs) is crucial for understanding water resources availability, contaminant transport, and the impacts of climate change on river systems. In this study, we introduce a global runoff routing model founded on hydraulic geometry principles and hydrologic catchments, specifically designed

Numerical scheme for solution of an approximation of Saint-Venant equation [PDF]

Contemporary Engineering Sciences, 2014
In the work [4] the Saint-Venant's one-dimensional differential model and kinematic approximation describing the free movement of water in an open channel is under consideration. This model is widely used for the calculation of the flow of rivers in the various fields of engineering.

Quantitative Evaluation of Baseflow Separation Methods Using an Integrated Hydrologic Model in a Snow‐Dominated Watershed

Water Resources Research, Volume 62, Issue 10, October 2026.
Abstract Baseflow constitutes over half of streamflow in mountainous headwaters of the western United States (US), making accurate quantification critical for water resource management. However, traditional baseflow separation methods are often arbitrary and ambiguous, complicating validation.

Time‐Varying Operation Policies With GRU‐Based Parameterization for Adaptive Multi‐Objective Reservoir Operation Under Climate Change

Water Resources Research, Volume 62, Issue 10, October 2026.
Abstract Designing reservoir operation policies that can adapt to non‐stationary hydroclimatic conditions is a major challenge for water resources management under climate change. This study develops an adaptive dynamic operation policy (ADOP), in which Gaussian radial basis functions (RBFs) are coupled with a gated recurrent unit (GRU)‐based ...

Physics‐Informed Fusion Learning for Nowcasting Fault Detection of Hydrological Multi Sensor Network

Water Resources Research, Volume 62, Issue 10, October 2026.
Abstract Urban flood monitoring demands timely, reliable decisions under urgent and often unseen conditions. However, faults in sensor networks can undermine response, leading to human and economic losses. To address these issues, we propose a Nowcasting Physics‐Informed (NPI) model for fault detection in streamflow sensors, with a 100‐min memory ...

Characteristic‐Aligned Control‐Volume Physics‐Informed Neural Network for Flood‐Wave Propagation and Roughness Estimation

Water Resources Research, Volume 62, Issue 10, October 2026.
Abstract Physics‐informed neural networks (PINNs) provide a promising framework for river hydrodynamic simulation and parameter inversion under sparse observations. However, spatial heterogeneity in channel geometry and roughness causes strong variations in flood‐wave propagation and parameter sensitivity, challenging local conservation and joint state‐
