Theme: Flood Streams

2/20/03 USFS

Based on stream layer. Juan de la Fuente pulled out altered channels by looking at 1997 color IR photos. 
Photo interpreted altered streams were augmented & verified by field review.

1997 Flood Altered Channels

Items in AAT of interest

Item called fldcode
Example tenmile_a Means creek name and segment (a = first segment) 

Item called New Means new debris flow track (not part of pre-existing stream layer)

Item called Year Means year occurred

Item called Alter Means whether or not the channel was altered (1 = altered)


Discussion:

Can have Alter = 1 and nothing in Fldcode - best pull out altered channels.
