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 ...

Evaluating Fire Indices for Fire Ignition and Spread Rate in the Western United States

open access: yesEarth's Future, Volume 14, Issue 8, August 2026.
Abstract Wildfires are complex events that are challenging to model. Researchers and land managers often rely on fire indices as a proxy of fire risk in operational forecasts and future projections. However, in the scientific literature, the choice of which fire index to use is often arbitrary and not tied to specific fire behaviors. Here, we provide a

Widespread Landslide Activity in an Extreme Wet Season and Implications for Regional Sediment Management, Eastern San Francisco Bay Area, California

open access: yesEarth and Space Science, Volume 13, Issue 8, August 2026.
Abstract Watershed sediment production is expected to increase in a warmer future with more extreme rain, with cascading effects throughout drainage and sediment‐transport networks. This study investigated landscape‐scale sediment movement in the eastern San Francisco Bay area, California, USA, during the extreme 2016–2017 wet season that brought major

Terrestrial Poor Ecohealth Areas Continue to Expand Across Asian Drylands

open access: yesEarth's Future, Volume 14, Issue 8, August 2026.
Abstract The 7th Rio declaration principle emphasizes global collaboration to protect and restore ecosystem health. While dryland ecosystem health (EH) remains critical to global sustainability agendas, its long‐term regional dynamics remain poorly constrained across the Asian drylands (AD), where land management decisions increasingly shape ecological

Hot Droughts Increase the Likelihood and Impacts of Abrupt Drought‐to‐Pluvial Transitions Worldwide

open access: yesEarth's Future, Volume 14, Issue 8, August 2026.
Abstract Hot droughts are intensifying under anthropogenic warming, yet whether extreme heat systematically alters the triggering of abrupt drought‐to‐pluvial transitions and their downstream impacts remains poorly understood. Here, we identify global drought‐to‐pluvial abrupt transition (DPAT) events and isolate the influence of antecedent thermal ...
