Third Order Reconstruction of the KP Scheme for Model of River Tinnelva [PDF]

Modeling, Identification and Control, 2017
The Saint-Venant equation/Shallow Water Equation is used to simulate flow of river, flow of liquid in an open channel, tsunami etc. The Kurganov-Petrova (KP) scheme which was developed based on the local speed of discontinuity propagation, can be used to

Dynamic response at the terminus of oblique intersecting joints subjected to stress waves

Deep Underground Science and Engineering, EarlyView.
This study derives the propagation equation for stress waves impinging upon nonlinear oblique intersecting joints. It analyzes the dynamic response at the terminus of nonlinear oblique intersecting joints subjected to stress waves. Abstract To investigate the dynamic response at the terminus of oblique intersecting joints subjected to stress waves, a ...

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, EarlyView.
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 ...

Affinification: A Fine Approximation of Deformations

Computer Graphics Forum, EarlyView.
Abstract We introduce affinification, a novel method for accelerating physics‐based animation of elastic solids. During a time‐dependent simulation, our method automatically partitions the space into affine and elastic regions depending on the deformation.

Saint Venants equations for dense-snow avalanche modelling

Ingeniería del Agua, 2020
La creciente preocupación por los riesgos naturales, como las avalanchas de nieve, ha propiciado el desarrollo de modelos numéricos ad hoc como una herramienta de soporte para su análisis y evaluación. Los modelos existentes para simulación de aludes se basan en la conservación de la masa y de la cantidad de movimiento, que son unas ecuaciones ...

Hybrid Data‐Driven and Physics‐Informed Learning of Cyclic Plasticity For Pipe Steel

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.
ABSTRACT An efficient and explainable machine learning (ML) approach is presented, replacing conventional material models based on the radial return mapping (RRM) algorithm for the constitutive modeling of cyclic plasticity in 3D. The application of transfer learning, based on an existing model for a separate class of steel, leads to a significant ...

Optimizing LID Practices in the Genoa Urban Drainage System Based on the Community's Call for Action Through Participatory Mapping

Journal of Flood Risk Management, Volume 19, Issue 2, June 2026.
ABSTRACT This paper presents a novel methodology for optimizing installation of low impact development practices (LIDs) in an urban hydrological catchment. This methodology helps stakeholders in deciding on what kind and area of LID must be installed in each sub‐catchment to attenuate pluvial flooding as a result of intense rain events.

Development of Next‐Generation Flood Inundation Maps: A Case Study in Kaohsiung City, Taiwan

Journal of Flood Risk Management, Volume 19, Issue 2, June 2026.
ABSTRACT Flood inundation mapping has become a critical reference for flood risk management, particularly for determining insurance premiums and formulating mitigation strategies in rapidly urbanizing areas with high population density. With recent advancements in mapping technologies and high computing capacity, high‐resolution spatiotemporal datasets
