From Gauged to Ungauged: Using Catchment Morphology to Guide the Transfer of Physics‐Informed Neural Network Discharge Predictions

Hydrological Processes, Volume 40, Issue 6, June 2026.
This study develops a transferability framework that combines ensemble clustering with hybrid PINN‐GRU models for discharge prediction in ungauged catchments. Using 10 catchment morphometrics, 117 subcatchments were grouped into four clusters, achieving strong within‐cluster transferability.

RS‐FloodXDepth: Enhancing Remote Sensing‐Derived Flood Extent and Estimating Flood Depth Using a Hydrologically Guided Region‐Growing Method and High‐Resolution DEMs

Water Resources Research, Volume 62, Issue 6, June 2026.
Abstract Remote sensing imagery is widely utilized for mapping flood extents. However, sensor limitations and environmental conditions often reduce mapping capability. Factors such as obscuring clouds, terrain shadows, and dense tree canopies frequently lead to significant information gaps and omission errors, particularly in forests and urban areas ...

On Saint-Venant’s principle in dynamic linear viscoelasticity [PDF]

Quarterly of Applied Mathematics, 1997
The Saint-Venant's principle (for elastostatics and elastodynamics) was earlier established in the linearized theory of quasi-static deformations for isotropic viscoelastic materials. Here the author extends the above principle to anisotropic bodies by investigating the spatial decay of dynamic viscoelastic processes in an anisotropic viscoelastic body

Coupling Waterlogging Hazard Assessment Based on SWMM–LISFLOOD Simulation in Chaoyang River Basin of Nanning, China

Journal of Flood Risk Management, Volume 19, Issue 2, June 2026.
ABSTRACT Urban stormwater waterlogging poses significant threats to public safety and property, making scientific and effective risk management a crucial element in China's whole‐area sponge city construction. This study evaluates waterlogging hazards in Nanning's Chaoyang River Basin using a SWMM–LISFLOOD coupled model to simulate 11 design storm ...

An Educational Software for Nonlinear Analysis of Truss Structures Using a Position‐Based FEM Formulation

Computer Applications in Engineering Education, Volume 34, Issue 3, May 2026.
ABSTRACT This study introduces a novel educational software for the analysis of 2D truss structures using a position‐based Finite Element Method (FEM). The software, named Truss Positional Finite Element Method Program (TPFEM), employs a Half‐Edge data structure to efficiently manage the geometric and topological information of truss elements.

Maneuverable Multilegged Locomotion through Anisotropically Arranged Soft Backbones in a Single‐Actuator Modular Miniature Robot

Advanced Intelligent Systems, Volume 8, Issue 4, April 2026.
A modular eight‐legged robot exploits anisotropically oriented soft I‐beam backbones to transmit vibration from a single unbalanced‐mass actuator, producing frequency‐dependent multimodal gaits. A pseudo‐rigid‐body model enables high‐fidelity MuJoCo simulation, while Bayesian parameter identification and reinforcement learning yield robust control ...

Local continuum consistent peridynamics with bond‐associated modeling and dynamic fracture

GAMM-Mitteilungen, Volume 49, Issue 1-2, March/June 2026.
Abstract This paper explores the theoretical foundations and practical challenges of peridynamics as a nonlocal continuum mechanics method. We establish connections between classical continuum mechanics principles and peridynamics formulations, with a particular focus on understanding how the pairwise force function in peridynamics relates to stress ...
