Research Interests
Dr. Shaw is interested in the erosion, transport, and deposition of sediment on the surface of Earth and other planets. He has studied these processes in rivers, deltas, coastlines, and turbidity currents. Although he employs simple models, laboratory experiments, and remote sensing, his primary scientific tool is the analysis of data collected from modern systems and stratigraphic outcrops. He uses these data to test and validate existing models, and to improve the conceptual understanding of sediment transport systems.
Current research questions:
- How do distributary channel tips (the downstream ends of channels) extend on prograding deltas?
- Can the backwater effect (prevalent on large river deltas) be measured in the stratigraphic record?
- What is the best technique for building new land on the Mississippi River delta?
- Can the bathymetry of a delta (see Figure 3) be determined from remote sensing?
- Can the stratigraphic record give us information about how hurricanes affect coastlines?
