A late Holocene onset of Aboriginal burning in southeastern Australia [PDF]

open access: yes, 2015
The extent to which Aboriginal Australians used fire to modify their environment has been debated for decades and is generally based on charcoal and pollen records rather than landscape responses to land-use change. Here we investigate the sensitivity of

Use of rare earth oxides as tracers to identify sediment source areas for agricultural hillslopes [PDF]

open access: yes, 2010
Understanding sediment sources is essential to enable more effective targeting of in-field mitigation approaches to reduce diffuse pollution from agricultural land.

Impacts of river engineering on river channel behaviour : implications for managing downstream flood risk [PDF]

open access: yes, 2020
Although knowledge of sediment transport has improved over the last 25 years, our understanding of bedload transfer and sediment delivery is still based on a limited set of observations or on models that make assumptions on hydraulic and sediment ...

Sediment Entrainment and Slump Blocks Limit Permafrost Riverbank Erosion

open access: yesGeophysical Research Letters, 2023
Climatic warming and permafrost thaw are predicted to increase Arctic riverbank erosion, threatening communities and accelerating sediment, carbon and nutrient cycling between rivers and floodplains.

Sediment Erosion Generated by a Coandă-Effect-Based Polymetallic-Nodule Collector

open access: yesJournal of Marine Science and Engineering, 2023
To date, hydraulic collection is the most widely considered technology in polymetallic-nodule mining, since there is no direct contact between hydraulic collectors and ocean floor.

Spatiotemporal Patterns of Hillslope Erosion Investigated Based on Field Scouring Experiments and Terrestrial Laser Scanning

open access: yesRemote Sensing, 2021
Hillslope erosion is an essential source of catchment sediment yield. However, the current understanding of the spatiotemporal patterns of field hillslope erosion processes is limited.

Mesoscale mapping of sediment source hotspots for dam sediment management in data-sparse semi-arid catchments [PDF]

open access: yes, 2020
Land degradation and water availability in semi-arid regions are interdependent challenges for management that are influenced by climatic and anthropogenic changes.

QUANTITATIVE ASSESSMENT OF SEDIMENT REDISTRIBUTION IN THE SICHUAN HILLY BASIN AND THE CENTRAL RUSSIAN UPLAND DURING THE PAST 60 YEARS

open access: yesGeography, Environment, Sustainability, 2014
Agricultural lands around the globe have been seriously affected by soil erosion and resultant on- and off-site eco-environmental problems. Quantitative assessment of sediment redistribution allows for explicit understanding the effects of natural and ...
