A simple non-equilibrium bedload transport equation for the formation of dune in a shallowwater flow over an erodible bed

E3S Web of Conferences, 2018
In this work, we consider the long-standing problem of capturing dune formation in an erodible-bed channel at subcritical speed by using a reduced order model of depth-averaged equations.

Assessing Deposit‐Derived Pyroclastic Flow Hazard at Stromboli (Italy): 1. Reconstruction of the Dynamics of the 11 September 1930 Event

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, -Not available-.
Abstract Stromboli volcano (Italy) is known for its persistent explosive activity punctuated by more energetic explosions called paroxysms. During paroxysms, pyroclastic density currents, triggered by the gravitational instability of hot pyroclastic deposits, can occur.

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 ...

Finite Element Modeling Of Saint-Venant Equations For Shatt-Al Hilla

Journal of Techniques, 2020
Shatt Al-Hilla was considered one of the important branches of Euphrates River that supplies irrigation water to millions of dunams of planted areas. It is important to control the velocity and water level along the river to maintain the required level ...

Conservative finite-volume forms of the Saint-Venant equations for hydrology and urban drainage [PDF]

Hydrology and Earth System Sciences, 2019
New integral, finite-volume forms of the Saint-Venant equations for one-dimensional (1-D) open-channel flow are derived. The new equations are in the flux-gradient conservation form and transfer portions of both the hydrostatic pressure force and the ...

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 ...

Modified Saint-Venant equations for flow simulation in tidal rivers

Water Science and Engineering, 2012
Flow in tidal rivers periodically propagates upstream or downstream under tidal influence. Hydrodynamic models based on the Saint-Venant equations (the SVN model) are extensively used to model tidal rivers.

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.
