INVESTIGATING GEOMORPHIC CHANGE USING A STRUCTURE FROM MOTION ELEVATION MODEL CREATED FROM HISTORICAL AERIAL IMAGERY: A CASE STUDY IN NORTHERN LAKE MICHIGAN, USA

South Manitou Island, part of Sleeping Bear Dunes National Lakeshore in northern Lake Michigan, is a post-glacial lacustrine landscape with substantial geomorphic changes including landslides, shoreline and bluff retreat, and sand dune movement.These changes Bath Salts involve interrelated processes, and are influenced to different extents by lake

In order to accurately predict the risk level of ancient timber structures under earthquake,22 evaluation indexes were selected, including Folding Walkers hazard of disaster-causing factors, susceptibility assessment of disaster environment, and vulnerability of disaster-bearing body, combined with seismic damage characteristics and structural char
