Strategic Roadmap for Addressing Microplastic Pollution in the Global South: Bridging Monitoring Gaps, Harmonizing Methods, and Building Analytical Capacity

Environmental Quality Management, Volume 35, Issue 4, Summer 2026.
ABSTRACT Microplastic (MP) pollution represents a growing environmental challenge, especially in tropical and subtropical coastal regions of the Global South, where methodological fragmentation, funding discontinuity, and dependence on external analytical infrastructure limit the production of comparable data and the formulation of evidence‐based ...

Artificial Intelligence and Objective‐Function Methods Can Identify Bankfull River Channel Extents

Water Resources Research
Bankfull channel extents are of fundamental importance in fluvial geomorphology, to describe the geomorphic character of a river, and to provide a boundary for further processing of morphologic and hydraulic attributes.

Terrestrial Analogs to Titan for Geophysical Research

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Saturn's moon Titan exhibits remarkable parallels to the Earth in many geophysical and geological processes not found elsewhere in the solar system at the present day. These include a nitrogen atmosphere with a condensible gas—methane—replacing the Earth's water, leading to an active meteorology with rainfall and surface manifestations ...

Investigating the influence of climate and volcanic surface aging on fluvial erosion: A case study of Réunion Island, Indian Ocean

Earth Surface Processes and Landforms, Volume 51, Issue 4, April 2026.
Réunion Island is marked by gradients in both precipitation and surface age. Analyzing correlations between metrics related to precipitation, age, and drainage basin morphology, we demonstrate how volcanic surface age impacts the effects of average precipitation and precipitation variability on fluvial erosion.

The need for a hydromorphological approach to Chilean river management La necesidad de un enfoque hidromorfológico para la gestión de los ríos chilenos

Revista Chilena de Historia Natural, 2012
The manuscript reflects the opinion of the authors about the need for a hydromorphological approach for the management of Chilean rivers. A brief state-of-the-art of the recent scientific advances on hydromorphological approach to river management is ...

Modelling the Sensitivity of Yukon River Biogeochemical Dynamics to Environmental and Chemical Drivers: Implications for Dissolved Organic Carbon

Hydrological Processes, Volume 40, Issue 4, April 2026.
We present a novel, process‐based, river model that effectively captures the interplay among hydrological, chemical, and soil parameters shaping riverine DOC transformations and reproduces observed DOC concentrations in the Yukon River. Sensitivity analysis highlights the importance of understanding the variability in DOC entering the headwater from ...

One application of mega-geomorphology in education [PDF]

One advantage of a synoptic view displaying landform assemblages provided by imagery is that one can often identify geomorphic processes which have shaped the region and which may affect the habitability of the area over a human life time.

When the Past Matters: How Model Initialization Can Lead to Surprises in Long‐Term Simulations in Glaciated Environments

Hydrological Processes, Volume 40, Issue 4, April 2026.
Discharge simulated using the physics‐based, spatially distributed hydrological modelling approach varies during the overlapping period across different simulation lengths, attributed to model initialization and inability of state updating. ABSTRACT Hydrological simulations are crucial for understanding water resource changes and developing climate ...
