For a wave equation involving p-Laplacian term Phragmen-Lindelöf type estimates
Sakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2013 Behaviours of the solutions to initial-boundary value problems in terms of spatial or time variables are investigateted by the teories such as Phragmen-Lindölef Theorem and Saint-Venant Principle.

An Informed Guide to Hydrodynamic Models Accounting for Large Wood and Logjams in Rivers
Earth Surface Processes and Landforms, Volume 51, Issue 10, October 2026.Large wood numerical modelling in rivers is used to investigate diverse aims, the most frequent being flood hazard and river restoration. The aim of models' application is correlated to the adoption of static or moving LW representation. LW modelling feasibility is affected by data availability, processes included within the model and model calibration.

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 ...

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

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.

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.

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 ...
