This paper presents the results of field measurements conducted in a small (19Ð4 ha) agricultural basin on the North Carolina coastal plain. The overall objective of the study is to determine the magnitude of soil erosion and sediment delivery as a result of storm runoff. The results suggest that erosion in the region is more rapid and extensive than previously thought. Fields at the site are experiencing accelerated soil loss, with rates often comparable to those of the southeastern Piedmont, a region long recognized as having rapid and problematic soil loss. This casts doubt on some assessments of the coastal plain as being a stable, non-eroding landscape. However, much of the soil mobilized is redistributed and stored within the watershed with only a small portion of the soil eroded from slopes leaving the basin on an event time frame.

Modelling and testing spatially distributed sediment budgets to relate erosion processes to sediment yields
TL;DR: The spatially distributed sediment budget model is described that assesses the primary sources (hillslope soil erosion, gully and riverbank erosion) and sinks (floodplain and reservoir deposition) of fine sediment for each link in a river network and is suitable for guiding the targeting of remediation measures within river basins to reduce downstream sediment yields.

Soil organic matter and CO2 emission as affected by water erosion on field runoff plots
Viktor O. Polyakov,Rattan Lal +1 more
TL;DR: In this paper, the effect of soil erosion on soil organic carbon (SOC) transport and mineralization was investigated on Miamian silty clay loam soil in central Ohio, where runoff plots 10, 20 and 30m long on a 7% slope under natural rainfall were used.

Dam-to-delta sediment inputs and storage in the lower trinity river, Texas
TL;DR: In this paper, a sediment budget of the lower basin shows that the effects of this disruption are undetectable in the lower river, and the sediment budget suggests that a majority of the sediment in this reach is likely derived from channel scour and bank erosion.
Bibliography of publications of 137 cesium studies related to erosion and sediment deposition
TL;DR: The assessment of soil erosion through the use of Cs-137 and related techniques as a basis for soil conservation, sustainable agricultural production, and environmental quality is discussed in this article.

TL;DR: In this paper, the authors present sediment yield data collected in 2006 for segments where hillslopes and channels form a fully connected network and contrast these with sediment yields measured for disconnected hilllopes.

The sediment delivery problem
TL;DR: In this paper, the limitations of the sediment delivery ratio concept by considering the problems of temporal and spatial lumping and its blackbox nature are reviewed, and the significance of recent concern for the role of sediments in the transport of nutrients and contaminants to sediment delivery studies is introduced.

Long-term sediment deposition in the riparian zone of a coastal plain watershed
TL;DR: In this article, the average annual rate of gross erosion minus sediment transport from the watershed was 35 Mg·ha·−1yr−1, with a range 7.6 to 92 Mgµhaµ−1r−1.

Fluvial sediment budgets in the North Carolina Piedmont
TL;DR: Phillips et al. as mentioned in this paper found that the relative order of magnitude of the allocation of eroded sediment for southern Piedmont rivers is colluvial, alluvial storage, and yield.

Hydraulic conditions for rill incision under simulated rainfall: A laboratory experiment
TL;DR: In this paper, a series of controlled laboratory experiments were conducted in order to obtain precise data on the hydraulic and sediment transport conditions during rill formation, and the relationship between sediment discharge, rill erosion, and flow hydraulics was found to be nonlinear, conforming to a standard power function in the form y = axb.
