Establishing a time‐varying flood‐wave impulse function combined with a dynamic machine‐learning technique in response to the disturbance of boundary conditions

Journal of Flood Risk Management, 2023
To seek other alternative approaches besides numerical methods, the linearized Saint Venant equations were utilized to derive the channel response functions for simulating streamflow.

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 ...

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.

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.

A well-balanced solver for the Saint Venant equations with variable cross-section [PDF]

Journal of Numerical Mathematics, 2015
AbstractIn this paper we construct a numerical solver for the Saint Venant equations. Special attention is given to the balancing of the source terms, including the bottom slope and variable cross-sectional profiles. Therefore a special discretization of the pressure law is used, in order to transfer analytical properties to the numerical method. Based

Quantifying Dynamic River Gains and Losses Using Inverse Water Temperature Modeling

Water Resources Research, Volume 62, Issue 7, July 2026.
Abstract Quantifying river gains and losses is critical for effective water resource management, particularly in systems with streamflow and water quality regimes dictated by variable groundwater and surface water exchanges. Traditional methods for estimating riverine exchanges often require significant resources and can be limited in temporal or ...

Decoding Compound Flood Risk Under Nonstationary Conditions: A Separable Parametric Framework Revealing the Heterogeneous Effects of Driving Mechanisms

Water Resources Research, Volume 62, Issue 7, July 2026.
Abstract Compound flooding in coastal environments arises from the interaction of extreme precipitation and elevated coastal water levels. Existing approaches typically rely either on process‐based hydrodynamic simulations or statistical characterizations of hazard drivers, constraining the capacity to quantify the contribution of individual mechanisms
