Description :
Between A.D. 2006 and 2008, the AA. completed annual surveys of 2 mercury-contaminated eroding banks, one forested and the other grass covered, along the gravel-bed, bedrock South River in Virginia. Gridded digital terrain models were created from bank topography data collected using a terrestrial laser scanner. Discussion of the model comparisons of the retreat on forested bank and grassy bank. The results suggest that three-dimensional gridded bare-earth models of bank topography may be required to accurately measure annual bank retreat in similar river systems.
