Topic	Sediment: Matthews Sediment Landslides by Type and Period 1933-1999

Caption:  The Chart Table SlideTypeXTab.dbf was derived from Matthews and Associates (2000) Table 12. The YEAR is the year of the aerial photos used to determine slide frequency and volumes and estimates are based on the period spanning back to the previous aerial photo year. The initial photos in 1942 are thought to reflect conditions from 1933-1942. Columns are types of major landslides DEBRIS_TOR = debris torrent, EARTHFLOW = earthflow, Gully = gully caused landslides, ROT/TRANS = rotational and translational landslide and SLIDES = debris slides See Info Links for more information and access to references.

 50 rows of a possible 3342 have been displayed.
