Description :
This study utilizes GIS modeling to determine if the location of 559 landslides in the 875 km2 catchment of the Middle Fork of the Payette River, Idaho, can be predicted based on topographic attributes and a wetness index generated by the DYNWET model. Slope and elevation were significantly related to landslide occurrence at this landscape scale. For now, the ability of rsearchers to effectively model landscape scale landsliding is more limited by the type, resolution, and quality of available data than by the quality of the landslide models.
