On Modeling and Constrained Model Predictive Control of Open Irrigation Canals

Journal of Control Science and Engineering, 2017
This paper proposes a model predictive control of open irrigation canals with constraints. The Saint-Venant equations are widely used in hydraulics to model an open canal.

Surface and Boundary Corrections in Peridynamics Using Optimized Nodal Influence Weights

International Journal for Numerical Methods in Engineering, Volume 127, Issue 14, 30 July 2026.
ABSTRACT Peridynamics (PD), similarly to some other nonlocal continuum theories, exhibits truncated interaction horizons near free surfaces, cracks, and voids in bounded domains. This loss of neighbors causes artificial surface effects and inconsistencies in the derivative and energy operators that persist under discretization refinement, limiting PD ...

Sequential Balloon Modeling for Robust Percutaneous Transluminal Angioplasty Simulation

International Journal for Numerical Methods in Biomedical Engineering, Volume 42, Issue 7, July 2026.
A sequential balloon modeling (SBM) strategy is proposed to simulate percutaneous balloon angioplasty (PTA) on severe stenosis and estimate post PTA permanent‐set in soft tissues. This strategy promotes simulation robustness. It is combined with a single‐stenosis parametric model and applied to a patient‐case reproduced using the parametric model as ...

On some numerical methods for solving the 1-D Saint-Venant equations of general flow regime. Part 1: Numerical methods

Vietnam Journal of Mechanics, 2002
Development of methods for numerical simulation of dike- or dam-break flood is one of essential problems of Fluid Mechanics at the present time. Many numerical methods for solving the 1-D Saint-Venant equations have been proposed. However, the analysis,

Trade‐Offs in Constraining Evapotranspiration Estimates in Complex Landscapes Using a Tracer‐Aided Ecohydrological Model

Hydrological Processes, Volume 40, Issue 7, July 2026.
Constraining evapotranspiration estimates in a large, heavily managed ET‐dominated catchment: trade‐offs among using discharge, isotopes and remote sensing products in calibrating an ecohydrological model. ABSTRACT Evapotranspiration (ET) links vegetation and soils to the atmosphere and can be the dominant water flux in many areas.

On the role of symmetry in Saint-Venant’s problem

International Journal of Solids and Structures, 2007
AbstractIn the relaxed Saint-Venant’s elastic problem, in virtue of Saint-Venant’s Postulate, the pointwise assignments of tractions at cylinder plane ends are replaced by the assignments of the corresponding resultant forces and moments. The solution indeterminacy so introduced is traditionally overcome by postulating that some specific features ...

Assessing Spatial Riverbed Clogging and Its Dynamics at the Reach Scale: A Coupled Approach Combining Field Measurements and 1D Hydro‐Sedimentary Numerical Modeling

River Research and Applications, Volume 42, Issue 6, Page 1293-1310, July 2026.
ABSTRACT Assessing spatial and temporal variability of clogging in gravel‐bed rivers is challenging because field methods typically rely on labor‐intensive measurements of fine‐sediment content, porosity, or hydraulic conductivity. Clogging is also highly dynamic, driven by hydro‐sedimentary conditions; yet few studies have examined it at large scales ...

Stable Water Isotopes Improve Calibration and Flow Path Identification in Integrated Hydrological Models

Water Resources Research, Volume 62, Issue 7, July 2026.
Abstract Hydrological models often exhibit equifinality, where different parameter sets produce similar hydrometric outputs but alter internal catchment processes and partitioning. Incorporating new information amongst calibration targets helps narrow the range of viable models.
