Non‐Linear Morphodynamic Response of Deltas to Extreme Events
Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.Abstract Deltas, the interface between riverine and coastal systems, host ∼500 million people and function as crucial ecological nexuses. The magnitude and frequency of extreme floods are projected to intensify as climate changes, yet the potential impacts on delta morphodynamics remain poorly understood.

Oikos, Volume 2026, Issue 5, May 2026.Habitat‐modifying plants engineer landscapes through plant‐environment feedbacks. The strength of these feedbacks is determined by above‐ and below‐ground traits shaping landscape morphology. Besides interspecific differences, recent findings highlight that intraspecific trait variation, such as shoot density, can also influence landscape morphology ...

On how spatial variations of channel width influence river profile curvature
Geophysical Research Letters, 2016 Longitudinal profiles of alluvial rivers usually exhibit upward‐concave curvatures at equilibrium. River profile concavity has been primarily attributed to sediment downstream fining and to streamwise increments of water discharge.

Long term behaviour of singularly perturbed parabolic degenerated equation [PDF]
, 2011 In this paper we consider models for short-term, mean-term and long-term morphodynamics of dunes and megariples. We give an existence and uniqueness result for long term dynamics of dunes.

Gully cut- and- fill cycles as related to agromanagement : a historical curve number simulation in the Tigray Highlands [PDF]
, 2015 Gully cut-and-fill dynamics are often thought to be driven by climate and/or deforestation related to population pressure. However, in this case-study of nine representative catchments in the Northern Ethiopian Highlands, we find that neither climate ...

Mapping River Bed Topography in Whitewater Rapids Using Bathymetric LiDAR
River Research and Applications, Volume 42, Issue 4, Page 886-900, May 2026.ABSTRACT Bathymetric LiDAR captures river topography efficiently for clear and shallow water, but for mountain rivers, whitewater rapids still pose challenges. This study proposes a novel method to enable the extraction of bottom returns specifically in turbulent whitewater sections.

A quantitative criterion to predict the occurrence of tidal bores [PDF]
, 2018 -Tidal bores are fascinating phenomena that occurs in the estuary of many tidal rivers worldwide. -Tidal bores have significant repercussions on ecology and morphodynamics of an estuary.

Positive Surge Propagation in Sloping Channels [PDF]
, 2017 A simplified model for the upstream propagation of a positive surge in a sloping, rectangular channel is presented. The model is based on the assumptions of a flat water surface and negligible energy dissipation downstream of the surge, which is ...

Water Resources Research, Volume 62, Issue 5, May 2026.Abstract Predicting long‐term effects of dam operation and restoration strategies on channel morphology remains a complex but essential challenge for maintaining fish habitat through effective reservoir management. We address this challenge by integrating a one‐dimensional morphodynamic model and a generalized fish habitat model using one‐dimensional ...
