Topic	Sediment: Matthews Landslides Volumes by Land-Use 1921-2000

 

Caption:  The chart above shows the total estimated sediment volumes (tons) from delivering landslides by land-use practice for each Big River sub-basin (1921-2000). Sediment volumes were computed by Matthews and Associates (2001). Roads and harvest related slides contributed a majority of the sediment to the Big River. Grasslands are an important sediment source in the Upper South Fork Big River and Daugherty Creek sub-basins. Matthews and Associates (2001) state: "Significant construction of new roads has led to increasing sediment yields from road surface erosion, despite improved practices. Under current conditions (1989-1999 period), management-related sediment delivery is estimated to be 51.7% of the total input."
