Gully Erosion Susceptibility Prediction Using High-Resolution Data: Evaluation, Comparison, and Improvement of Multiple Machine Learning Models

Remote Sensing
Gully erosion is one of the significant environmental issues facing the black soil regions in Northeast China, and its formation is closely related to various environmental factors.

Assessing the Vulnerability of an Inuit Archaeological Site in a Changing Periglacial Environment: A Novel Multimethod Geophysical Approach in Arctic Geoarchaeology

Archaeometry, EarlyView.
ABSTRACT With northern regions warming at twice the global rate, assessing the state of archaeological sites in these areas is critically important. In this study, we used a multimethod geophysical approach (ERT, GPR, and EMI) to characterize the current geocryological conditions of an Inuit archaeological site on South Aulatsivik Island (Labrador ...

Debris at the edge: sedimentological dynamics of Hintereisferner's evolving terminus and glacial forefield, Austrian Alps

Boreas, EarlyView.
The interaction between glaciers and the debris accumulating on their surfaces is critical as the Earth warms, with consequences for ice dynamics, hydrology and mass balance together with slope and sedimentary processes. Understanding this interaction is necessary since it influences ablation rates, sediment and meltwater pathways.

Variations in downslope activity and bottom current dynamics in a land‐detached submarine channel system since the Last Glacial Maximum

Sedimentology, EarlyView.
ABSTRACT The Gollum Channel System is a land‐detached large‐scale canyon‐channel system situated offshore southwest Ireland on the Northeast Atlantic margin. The system has been considered inactive with downslope gravity flows since the last glacial period, but geophysical data in some of its branches do suggest Holocene activity.

Factors controlling the morphology and volume (V)–length (L) relations of permanent gullies in the Northern Ethiopian Highlands [PDF]

, 2013
Small-scale aerial photographs and high-resolution satellite images, available for Ethiopia since the second half of the twentieth century as for most countries, allow only the length of gullies to be determined.

Morphometric characteristics and their influence on soil hydrological properties in Kiltie watershed, Upper Blue Nile Basin, Ethiopia

Agrosystems, Geosciences &Environment, Volume 9, Issue 1, March 2026.
Abstract Morphometric analysis is crucial for watershed management, especially for estimating infiltration rate and erosion characteristics. However, there is limited research on the relationship between morphometric characteristics and soil hydrological properties in the Kiltie watershed.

Colonial Bias in AI Training Data: Prompting Sora to Generate Images of Aotearoa New Zealand's Historical Past

Kōtuitui: New Zealand Journal of Social Sciences Online, Volume 21, Issue 1, March 2026.
This paper examines how generative artificial intelligence (AI) reproduces colonial visual tropes when tasked with representing Aotearoa New Zealand's historical past. Using OpenAI's Sora as a case study, the analysis investigates AI‐generated images prompted to depict (1) precolonial landscapes, (2) first contact between Māori and Europeans, (3 ...

Optimizing Flood Hazard Zonation and Planning Landscape‐Based Mitigation Measures in Gimba Sub Watersheds, Northeastern Ethiopia: A Comprehensive Approach

Journal of Flood Risk Management, Volume 19, Issue 1, March 2026.
ABSTRACT Flooding remains one of the most critical natural hazards threatening livelihoods, infrastructure, and ecological systems in Ethiopia's highland landscapes. This study presents a rigorously integrated, multi‐criteria flood risk assessment that combines the Analytical Hierarchy Process (AHP) with GIS‐based spatial modeling to delineate ...

Comparison of Gully Erosion Susceptibility Mapping Using Weight of Evidence and Frequency Ratio Models at Sanganeh Kalat Basin

تحقيقات جغرافيايی, 2018
Gully erosion is the most advanced type of water erosion in watersheds that produces large volumes of sediment that and cause a lot of damage. Thus mapping susceptibility to gully erosion and identification of factors can help managers and decision ...
