Abstract

Gully erosion of cultural sites in Grand Canyon National Park is an urgent management problem that has intensified in recent decades, potentially related to the effects of Glen Canyon Dam. The AA. used intensive ground-based surveys and field geomorphic data to identify gullying processes and erosion trends at 9 sites during 2002. In addition, they used very detailed terrain models from aerial photogrammetry to perform an erosion-threshold analysis. The objectives are to better understand and quantify gully erosion in Grand Canyon and provide the first evaluation of the effectiveness of installed erosion-control structures
