M.S. Research Overview
Joanna M. Reuter
How quickly do landscapes erode? How do erosion rates vary across
the landscape? Is it possible to predict erosion rates based mappable landscape
characteristics, such as topography, tectonics, climate, bedrock geology, and
vegetation? From a knowledge of erosion patterns, what inferences can we make about
how landscapes change over time? What impact have humans had on sediment dynamics?
These are all questions that motivated my M.S. research.
I utilized two tools to try to get some answers. One is 10Be measured
in fluvial sediment, which allows us to infer erosion rates for entire drainage
basins on a multi-millennial time scale. The second tool is GIS, which
I used to characterize the drainage basins with 10Be measurements.
The bulk of my work was in the Susquehanna River Basin, but I also compiled and analyzed existing 10Be data sets
from around the world. For a quick overview of results, see the powerpoint presentations
below, and for more detail, check out the thesis or other pdfs below, or check to see
if any of the papers that we have submitted for publication are out yet.
Presentations and documents for download
- M.S. Thesis (pdf, 18 MB)
The thesis focuses on basin-scale erosion rates in the Susquehanna River Basin. Two chapters are intended for publication. The thesis also includes a chapter on the global compilation of 10Be data from fluvial sediment. Appendix A documents GIS methods in detail.
- Defense presentation (ppt, 7 MB), March 2005
Results and discussion of sediment dynamics in the Susquehanna River Basin; also includes an overview of the global compilation of 10Be data.
- NE GSA poster (ppt, 5 MB), March 2005
Presented in the GIS session, this poster focuses on utilization of GIS for the selection of drainage basins for sampling.
