Description :
Multispectral digital imagery acquired from Soda Butte and Cache Creeks, Montana and Wyoming was used in conjuction with field data to classify and map hydrogeomorphic stream units on 4 stream reaches. The morphologic units that were field mapped were eddy drop zones, glides, low gradient riffles, high gradient riffles, lateral scour pools, attached bars, detached bars, and large woody debris. Unsupervised and supervised classifications of the imagery were used to develop a Maximum Joint Probability classification and an Alternative Joint Probability classification of the stream reaches.
