TL;DR: In this paper, three topographic data sources were used to generate the model input for an agricultural field with a riparian buffer, and the runoff and sediment transport in the system was then simulated for three years.

Abstract: Riparian buffers are a promising tool in efforts to reduce sediment contribution to streams.
Models that predict the capacity of buffers to trap sediment have recently been developed. A number of
parameters that are required to conduct such modeling efforts are derived from the topography of the site.
In this study, three topographic data sources were used to generate the model input for an agricultural
field with a riparian buffer. The runoff and sediment transport in the system was then simulated for three
years. As a result, the area that contributed runoff and sediment to the buffer was substantially different
for each of the topographic data sources. In addition, the predicted runoff and sediment loss from the
field was different for each case. Finally, the predicted sediment delivered to the stream was substantially
affected by the accuracy of the topographic data source.

TL;DR: In this paper, the authors used linear regression and Spearman ranking analyses to determine if the methods represented trends in overland flow length as suggested by manual delineation of contour lines, and found that the results of rank and regression analyses suggest that these more diverse ANIMs are in fact more accurate than the flow accumulation method.

Management effects on runoff and sediment transport in riparian forest buffers
TL;DR: In this paper, the effect of forest management within a Coastal Plain riparian forest buffer system (RFBS) on runoff and sediment transport over a four year period was evaluated, which indicated that riparian forests within a RFBS may be managed for economic return to the land owner without adversely affecting the runoff and degradation reduction function performed by these buffer systems.

A GIS method for riparian water quality buffer generation
TL;DR: The GFS method presented here provides a promising solution to the delineation of riparian water quality buffers and the evaluation of environmental buffer regulations because it integrates a scientifically-tested model of variable buffer width delineation into a GIS frame-work.
