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.

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 4, April 2026.Abstract River bifurcations control water and sediment distribution in fluvial systems, but the physical mechanisms governing sediment partitioning remain poorly validated in natural rivers. We present a comprehensive field test of nodal point relations using radio frequency identification (RFID) tracking of 376 gravel clasts through a meandering river

Effects of Creek Topology on Salinization of Coastal Marsh Due To Storm Surges
Water Resources Research, Volume 62, Issue 4, April 2026.Abstract Creek topology varies widely across coastal marshes and strongly influences surface and subsurface flow patterns. These flow dynamics, in turn, affect salt transport within the marsh system. Both processes are critical in storm surge inundation and consequent subsurface salinization.

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.

Remote sensing of intertidal morphological change in Morecambe Bay, U.K., between 1991 and 2007 [PDF]
, 2010 Tidal Flats are important examples of extensive areas of natural environment that remain relatively unaffected by man. Monitoring of tidal flats is required for a variety of purposes. Remote sensing has become an established technique for the measurement

A Generalized Framework for Flow Resistance in Canopies and Granular Beds
Water Resources Research, Volume 62, Issue 4, April 2026.Abstract This study presents a generalized, theoretically grounded semi‐empirical framework for estimating flow resistance through canopies and granular beds, both of which are common in engineering and environmental applications. Derived from fundamental fluid mechanics principles, the proposed formulation significantly reduces reliance on empirical ...

The Mullins effect in the wrinkling behavior of highly stretched thin films [PDF]
, 2018 Recent work demonstrates that finite-deformation nonlinear elasticity is essential in the accurate modeling of wrinkling in highly stretched thin films.

Water Resources Research, Volume 62, Issue 4, April 2026.Abstract Understanding large wood (LW) dynamics on floodplains is important for closing wood budgets and predicting hazards associated with LW. We conducted 38 experiments in a fixed‐bed flume to examine how forest stand density (FSD), wood transport regime, and overbank flood magnitude affect floodplain LW retention.

New design parameters for biparabolic beach profiles (SW Cadiz, Spain) [PDF]
, 2019 165 profiles of seventy-one beaches along the Gulf of Cadiz (SW, Spain) were studied to improve the formulation of the beach profile in tidal seas. Maritime climate, degree of energy exposure and size of the sand grains were taken into account to study ...
