Abstract
To predict the relative risk of soil erosion from various parts of the South Branch Buffalo
River watershed, southwest of Moorhead, MN, the surficial geology of the area has been
studied and a methodology has been developed. The methodology comprises the use of
the sediment production component of the United States Department of Agriculture
AnnAGNPS model to quantify surface erosion rates and sediment yields from the upland
areas, and a sediment routing model to estimate the channel bank migration rates and the
supply of sediment from stream bank sources. The AnnAGNPS model was calibrated
using the suspended sediment load observations made at Sabin, Minnesota during 1978.
The calibrated model predicts a sediment yield of 14,400 tons/yr at the watershed outlet
(13.0 tons/km²/yr) for the years 2002-2005. This amount is nine times larger than the
channel bank erosion estimate of 1600 tons/yr (1.45 tons/km²/year). Modifications to the
AnnAGNPS program allow routing multiple grain sizes of sediment produced in the
watershed, including aggregated pellets formed from silts and clays, and predicting the
likely locations of sediment deposition in the river network.
