||Upper Big River
||Sediment: Matthews Landslides Volume Delivered, Upper Basin 1921-2000
||Caption: The chart above shows Matthews and Associates (2001) total computed sediment delivery quantities for each Upper Big River sub-basin per analysis period. Estimates are generated from aerial photographs. The largest landslide sediment contributions appear to have occurred during the 1937-1952 and 1953-1965 periods. Current slide activity continues to contribute large volumes of sediment. Matthews and Associates (2001) note, the actual number of slides in the 1921-1936 period is likely an underestimate, since 1936 aerial photo coverage was unavailable for the eastern half of the watershed.
