Frontiers in Marine Science, 2022 The water discharge and sediment load have been increasingly altered by climate change and human activities in recent decades. For the Pearl River, however, long-term variations in the sediment regime, especially in the last decade, remain poorly known ...

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

Estimating River Sediment Discharge in the Upper Mississippi River Using Landsat Imagery
Remote Sensing, 2020 With the decline of operational river gauges monitoring sediments, a viable means of quantifying sediment transport is needed. In this study, we address this issue by applying relationships between hydraulic geometry of river channels, water discharge ...

Frontiers in Earth Science, 2018 Glaciers expel large amounts of water and sediments, and the discharge of both is influenced by glacier retreat. Because the majority of sediment originates subglacially, as opposed to proglacially, focus must be given to subglacial sediment discharge ...

Emergent stationarity in Yellow River sediment transport and the underlying shift of dominance: from streamflow to vegetation [PDF]
Hydrology and Earth System Sciences, 2019 Soil erosion and sediment transport play important roles in terrestrial landscape evolution and biogeochemical cycles of nutrients and contaminants. Although discharge is considered to be a controlling factor in sediment transport, its correlation with ...

Enrichment of organic carbon in sediment transport by interrill and rill erosion processes [PDF]
, 2008 Erosion and loss of organic carbon (OC) result in degradation of the soil surface. Rill and interrill erosion processes on a silt loam soil were examined in laboratory rainfall and flume experiments.

Empirical and analytical methods to characterize the efficiency of floods to move sediment in a small semi-arid basin [PDF]
Hydrology and Earth System Sciences, 2018 Over a long multi-year period, flood events can be classified according to their effectiveness in moving sediments. Efficiency depends both on the magnitude and frequency with which events occur.

Multi-temporal runoff-sediment discharge relationships [PDF]
, 2022 To understand the runoff-sediment discharge relationship , this study examined the annual runoff and sediment discharge data obtained from the Tangnaihai hydrometric station. The data were decomposed into multiple time scales through Complete Ensemble Empirical Mode Decomposition with adaptive noise (CEEMDAN). Furthermore, double cumulative curves were

Anabranching and maximum flow efficiency in Magela Creek, northern Australia [PDF]
, 2004 Anabranching is the prevailing river pattern found along alluvial tracts of the world's largest rivers. Hydraulic geometry and bed material discharge are compared between single channel and anabranching reaches up to 4 times bank-full discharge in Magela

Sediment transport capacity response to variations in water discharge in pressurized subglacial channels [PDF]
The CryosphereSediment transport capacity in both subaerial and subglacial channels depends on the shear stress exerted across the channel bottom, which varies with water velocity and channel width.
