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).

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.

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.

Inverse source problem related to one-dimensional Saint-Venant equation [PDF]

Applicable Analysis, 2020
The one-dimensional Saint-Venant equation describes unsteady water flow in channels and is derived from the one-dimensional Euler equation by imposing several physical assumptions.

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.

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 ...

Analyzing and Quantifying Key Sources of Uncertainty in Intermittent Water Supply Simulation: Supply Characteristics, Household Tank Size and Time Series of Water Consumption From the Household Tanks

Water Resources Research, Volume 62, Issue 3, March 2026.
Abstract Many researchers have used deterministic models to address issues in intermittent water supply (IWS) systems, such as inequitable distribution, but these models often overlook key uncertainties. IWS systems vary widely in practices and operations, introducing uncertainties in areas like water consumption pattern, supply characteristics, and ...

Climate‐Change Projections of Flow Distribution Across the Rhine Delta

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 3, March 2026.
Abstract We project climate‐driven changes in flow and sediment partitioning across the Rhine delta using a hybrid one‐dimensional model informed by two‐dimensional sediment‐partitioning data. Simulations spanning 150 years and 540 km show a continued shift of discharge toward the Waal branch, while the effects of historical interventions gradually ...
