Topic	Sediment: Matthews Landslides Volumes per Land-Use Daugherty Cr

 

Caption:  The chart above shows Matthews and Associates (2001) total computed sediment delivery quantities in the Daugherty Creek basin per land-use. Road failures and slides in grassland areas contributed large sediment volumes in this basin. Harvested areas also important sediment sources. 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." Estimates are generated from aerial photographs.
