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.

Comparing Active Learning for Satellite Imagery: Contrastive Learning, Diversity, Confidence Sampling, and Cold Start Strategies

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
In this article, we investigated and compared common active learning strategies for classification and semantic segmentation tasks using satellite imagery.

SEDIMENT TRANSPORT IN A TIDAL

open access: yesCoastal Engineering Proceedings, 1972
Tidal flow and suspended-sediment discharge were measured in or near the inlet to Bolinas Lagoon through seven ebbtides and six floodtides. The highest flows and suspended-sediment discharges occurred during the major daily ebbtide. Most transported sediment was sand and most sediment deposited in the lagoon was sand.

Analytical model for flux saturation in sediment transport

open access: yes, 2014
The transport of sediment by a fluid along the surface is responsible for dune formation, dust entrainment and for a rich diversity of patterns on the bottom of oceans, rivers, and planetary surfaces.

Soil carbon and nitrogen erosion in forested catchments: Implications for erosion-induced terrestrial carbon sequestration [PDF]

open access: yes, 2015
Lateral movement of organic matter (OM) due to erosion is now considered an important flux term in terrestrial carbon (C) and nitrogen (N) budgets, yet most published studies on the role of erosion focus on agricultural or grassland ecosystems.

A hydro-morphodynamic model integrating extended sediment particle size distribution and flocculation processes for better simulating hydro-sedimentary fluxes

open access: yesE3S Web of Conferences, 2018
Many studies focusing on suspended sediment transport modelling in river systems only consider one class of sediment grain size. Rather recently, the SISYPHE sediment transport model has integrated sand-mud mixture transport processes using two classes ...

Impacts of tidal flat reclamation on suspended sediment dynamics in the tidal-dominated Wenzhou Coast, China

open access: yesFrontiers in Marine Science, 2023
Reclamation of tidal flats is one of the engineering measures of expanding land area and developing the economy in coastal areas; however, this process disturbs the natural processes of the tidal flat system.

2DV modelling of sediment transport processes over full-scale ripples in regular asymmetric oscillatory flow [PDF]

open access: yes, 2008
Wave-induced, steep vortex ripples are ubiquitous features in shallow coastal seas and it is therefore important to fully understand and model the sediment transport processes that occur over them.

Fluvial Characteristics of the Magdalena River (Colombia) and a Nature-Based Solution for Navigation Conditions

open access: yesHydrology
This study analyzes the hydro-morphological dynamics of the lower 40 km of the Magdalena River (Colombia), with particular emphasis on the reach between Malambo and the river mouth at Bocas de Ceniza.

Mass wasting triggered by seasonal CO2 sublimation under Martian atmospheric conditions: Laboratory experiments [PDF]

open access: yes, 2016
Sublimation is a recognized process by which planetary landscapes can be modified. However, interpretation of whether sublimation is involved in downslope movements on Mars and other bodies is restricted by a lack of empirical data to constrain this ...
