Conclusions
In summary, a compilation of topographic and photographic information on Colorado River
sandbars is being developed at Northern Arizona University Department of Geology. The
preliminary GIS-based analyses of the sandbar study data base demonstrate the value of GIS
systems and supporting data bases as an analytical tool for identifying morphological changes
in sediment storage. GIS-based analysis should be an integral part of future monitoring plans
for Grand Canyon National Park.
The second study was conducted by BIO/WEST INC., a private contractor employed by GCES
to generate current and collect historic fisheries data in the Grand Canyon. BIO/WEST
addressed the archival needs of GCES by incorporating both current and historical fisheries data
through a developed GIS module.
