Evaluating the importance of surface soil contributions to reservoir sediment in alpine environments: a combined modelling and fingerprinting approach in the Posets-Maladeta Natural Park
Alpine environment soil ecosystem soil erosion rainfall
2015/1/6
Soil in alpine environments plays a key role in the development of ecosystem services and in order to maintain and preserve this important resource, information is required on processes that lead to s...
Use of rare earth oxides as tracers to identify sediment source areas for agricultural hillslopes
rare earth oxides sediment source areas agricultural hillslopes
2014/12/31
Understanding sediment sources is essential to enable more effective targeting of in-field mitigation approaches to reduce diffuse pollution from agricultural land. In this paper we report on the appl...
Incipient sediment motion across the river to debris-fl ow transition
Incipient sediment motion the river debris-fl ow transition

Sediment transport in mountain channels controls the evolution of mountainous terrain in response to climate and tectonics and presents major hazards to life and infrastructure worldwide. Despite its ...
Increase in acetate concentrations during sediment sample onboard storage: a caution for pore-water geochemical analyses
acetogen microbial community pore water marine sediment storage condition
2017/4/11
Microbial activity in marine sediment plays an important biogeochemical role in cycling of carbon and other elements.
Acetate is a key intermediate of various microbial metabolic pathways. In this st...

Spatial and temporal trends for water-fl ow velocity and bed-material sediment transport in the lower Mississippi River
Spatial and temporal trends water-fl ow velocity bed-material sediment transport the lower Mississippi River
2014/4/8
Where rivers near the coastline, the receiving basin begins to infl uence fl ow, and gradually varied, nonuniform fl ow conditions arise. The section of the river affected by nonuniform fl ow is typic...
Is the critical Shields stress for incipient sediment motion dependent on channel-bed slope?
critical Shields stress incipient sediment motion channel-bed slope
2014/4/8
Data from laboratory flumes and natural streams show that the critical Shields stress for initial sediment motion increases with channel slope, which indicates that particles of the same size are more...
