Cause and effect relationship, clearing-erosion-flooding, 
Whitemud River Watershed, Manitoba; winter C (date: 5-1-74), 
spring melt A (23-4-74) and summer B (16-6-74) can be 
compared with fall 73 D (18-9-73). Note the snowcovered high 
plateau (A: 1) and the inundated farmlands (A: 2). B shows 
erosion (B: 1) on steep slopes cleared of tree cover. 
Cleared slopes cause rapid run-off in spring and contribute 
to flooding. 
Springmelt inundation of sedge wetlands, Interlake, Manitoba. 
E, band 5, shows fall (15-8-73) conditions; light tones in 
between darker drumlines are wetlands. F, band 7, shows 
the inundation areas during snowmelt (23-4-74).
