Beach Gold and Heavy Mineral Concentrates on Tiwai Spit Gravel Strand Plain, Southland, New Zealand

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 69, Issue 3, September 2026.
The Holocene Tiwai Spit on Foveaux Strait is a 12 km by 2 km gravel‐dominated strand plain, ∼10 m above present sea level. Gravel clasts are dominated by well‐rounded quartz cobbles, pebbles and granules derived from Otago Schist 200 km to the north in evolving river drainage systems during late Cenozoic.

River Sand and Gravel Mining: Global Drivers, Impacts, and Pathways for Sustainable Management

open access: yesReviews of Geophysics, Volume 64, Issue 3, September 2026.
Abstract River sand and gravel are mined worldwide at volumes that now rival their natural replenishment, yet quantitative knowledge of this mining activity and its consequences lags far behind many other global environmental pressures. We synthesize 411 peer‐reviewed studies published since 1974 within a new Driver‐to‐Management Pathway for ...

Coupling Water Purification and Carbon Sequestration at Various Spatial Scales From Supply and Demand Perspective

open access: yesLand Degradation &Development, Volume 37, Issue 13, Page 8986-9007, 15 August 2026.
ABSTRACT Balancing ecosystem‐service supply and demand is central to understanding both the natural and social dimensions of ecosystem services and to enhancing human well‐beings. Concurrently, collaborative efforts are underway to improve multiple ecosystem services, including the promotion of carbon neutrality and water purification (WP) within basin

Spatial variability of denudation rates and transient landscape adjustment in low‐deforming mountains (the Strengbach catchment, Vosges Mountains, France)

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 8, August 2026.
Erosion across the landscape is described at first order by a limited number (nine) of homogenous geomorphological and lithological domains. Using a dense set of basin wide denudation rates, it is possible to retrieve the contribution of each litho‐morpho‐domains as a function of their respective surface.

Morphodynamic adjustment in a watershed affected by megafires: Deadman River, British Columbia, Canada

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 8, August 2026.
The Deadman River watershed (British Columbia, Canada) was severely impacted by the Sparks Lake Fire in 2021. Timelapse photogrammetry reveals sharp post‐fire channel widening and increase in migration rate. Through multispectral remote‐sensing analysis, these morphodynamic changes are related to burn severity affecting the watershed.

Tracing river dynamics: Multi‐temporal planform evolution and morphological change analyses in a meandering reach using high‐resolution satellite imagery and UAV data

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 8, August 2026.
High‐resolution satellite imagery and UAV data enabled detailed morphometric parameter calculation, meander classification and multi‐epoch change detection for the Atrak River's meandering channel. Our results reveal rapid, episodic migration and a nearly tenfold surge in bank erosion triggered by the 2019 extreme flood, with persistent instability at ...
