Did wind fetch affect the abundance and size of tree throw events during Hurricane Isabel?
This project was inspired by our “big event” during the class in Fall 2003, Hurricane Isabel. The students became interested in how much sediment was transported by tree throw during the hurricane after we did a lab on this shortly after the event. They tested the hypothesis that fetch was important by going to 3 locations – one along a major river, one on a small lake, and one in intact forest – and examined the frequency and size of tree throw within similar areas. The measurements included diameter and volume of the root ball, compass direction of tree fall, breast height tree diameter, and length of wind fetch. The students involved also had training in GIS, and used ArcView and digital orthophotoquads to map the location of their field sites. The findings were not as expected, where fetch was directly related to the magnitude of tree throw, but concluded that elevation in tandem with fetch may be the important control.
