Application of erts-1 multispectral imagery to monitoring the present episode of accelerated erosion in southern arizona

Content Provider	NASA Technical Reports Server (NTRS)
Author	Cooley, M. E. Morrison, R. B.
Copyright Year	1973
Description	An episode of accelerated arroyo-cutting and sheet erosion commenced about 1890 in southern Arizona, following several thousand years of generally sluggish erosion. For a 17,000-square-mile study area, ERTS-1 images, supplemented by ultrahigh-altitude (U-2 and RB-57) airphotos, are proving effective for producing the first comprehensive maps showing the distribution and seriousness of the post-1890 erosion features, for monitoring new erosion changes, and for assessing the effectiveness of ameliorative measures. Such data are essential for understanding and controlling the accelerated erosion, a key environmental problem in this region.
