Effects of Gravitational Settling and Riverbed‐Induced Mortality on the Transport of Drifting Fish Eggs in Rivers

Water Resources Research, Volume 62, Issue 1, January 2026.
Abstract Drifting fish eggs are a type of fish egg with a slightly higher density than water, requiring floating for successful hatching. While it is acknowledged that interaction with the riverbed surface can cause mortality of the eggs, the impact of this process on their downstream transport remains unclear.

Remote Sensing and Hydrodynamic Modelling to Assess Riparian Vegetation and Geomorphological Responses to Flow Regulation, Rio Chama, New Mexico, USA

Ecohydrology, Volume 18, Issue 8, December 2025.
ABSTRACT The alteration of the hydrological regime caused by damming remains a critical challenge for river systems. Rio Chama, a highly regulated river, has undergone severe alterations in its hydrological regime due to a series of dams that impact sediment transport mechanisms and riparian vegetation dynamics.

Hydrodynamic Removal of Sediments in Open Irrigation Channel

Modern Agriculture, Volume 3, Issue 2, December 2025.
The experimental study investigated the hydraulic behaviour of particle transport in an irrigation channel equipped with submerged longitudinal structures designed to reduce the effective cross‐sectional area. The findings demonstrate that the placement of parallel barriers along the flow axis generates localized acceleration and turbulence, which ...

Morphodynamic Modeling of a Flood Event at a Restored Alpine River Reach

River Research and Applications, Volume 41, Issue 10, Page 2136-2156, December 2025.
ABSTRACT Morphodynamic models are essential tools for estimating sediment dynamics along river reaches. A wide range of bedload transport equations is available, and applying these models to river restoration projects and river widenings requires simplifying assumptions about slope effects, secondary currents, and bank failure, introducing significant ...

A Comparative Study of Physics‐Informed and Data‐Driven Neural Networks for Compound Flood Simulation at River‐Ocean Interfaces: A Case Study of Hurricane Irene

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 4, December 2025.
Abstract Simulating compound flooding (CF) at the river‐ocean interface within large‐scale Earth System Models (ESMs) presents significant challenges due to complex interactions between river discharge, storm surge, and tides. This study assesses the comparative advantages of physics‐informed and data‐driven machine learning (ML) approaches for ...
