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.

Assimilation of SWOT Reach Water Surface Elevation Product Toward Enhanced Basin‐Scale Discharge Modeling

Earth and Space Science, Volume 13, Issue 4, April 2026.
Abstract The high‐resolution measurements of surface water recorded by the recently launched Surface Water and Ocean Topography (SWOT) mission offers unprecedented opportunities toward accurate characterization of basin‐scale river discharge. This paper presents the first India‐centric study regarding the potential of assimilation of SWOT Water Surface

Street‐to‐Pipe Diagnosis of Compound Rain–Tailwater Flooding in a Coastal Combined Sewer System: Sewer Pre‐Filling and Outfall Throttling

Earth's Future, Volume 14, Issue 4, April 2026.
Abstract Compound flooding in coastal cities occurs when heavy rainfall coincides with tide‐driven tailwater that reduces combined sewer system (CSS) discharge capacity, yet this coupling is rarely quantified from street to pipe scale. We develop a high‐resolution 1‐D/2‐D drainage–inundation model for Hoboken, New Jersey, calibrating the 1‐D drainage ...

Evaluation of Flood Forecasting Input Uncertainties in Transitional Inland‐Coastal Low‐Gradient Rivers

JAWRA Journal of the American Water Resources Association, Volume 62, Issue 2, April 2026.
ABSTRACT Flood forecasting in transitional inland‐coastal low‐gradient rivers is challenging due to complex interactions among meteorological, hydrologic, and coastal processes. This study evaluates how uncertainties in key forecast inputs affect flood prediction accuracy in such settings, using the Vermilion River (south‐central Louisiana).

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.

Application of Discontinuity Layout Optimization to Metal Shells and Assemblies

International Journal for Numerical Methods in Engineering, Volume 127, Issue 5, 15 March 2026.
ABSTRACT Discontinuity Layout Optimization (DLO) provides a computationally efficient means of determining collapse loads and associated failure mechanisms across a wide spectrum of plasticity problems. The classical DLO method has focused separately on in‐plane and out‐of‐plane plasticity.

Three‐Dimensional Simulation of Crack Initiation in ice Shelves at Pinning Points

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 1, March 2026.
ABSTRACT Ice shelves are large ice masses floating on the ocean that are still connected to the inland ice of a glacier. Due to high elevations in the bathymetry, the ice shelf can be partially grounded. These areas are called ice rises that act as pinning points.

Approximate Stability Analysis of Omega‐Stringer Stiffened Composite Panels

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 1, March 2026.
ABSTRACT Thin‐walled composite structures are widely used in weight‐critical applications such as aircraft and spacecraft. However, ensuring the stability of such structures under various load cases remains a key challenge in their design and optimization.

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.

Efficient Data Assimilation Method for Optimizing Prediction of Flow Field and Sediment Transport in Open Channel

River Research and Applications, Volume 42, Issue 3, Page 580-593, March 2026.
ABSTRACT Accurately predicting open‐channel flow under complex conditions remains a challenge. This study introduces a novel synergetic self‐adaptive data assimilation (DA) framework, using a proportional‐integral‐derivative (PID) controller to dynamically calibrate the bed roughness parameter k s in a shallow‐water equation model (via the momentum ...
