Associate Professor Peter Nelson co-authored two papers in the Journal of Geophysical Research: Earth Surface on the role of bedrock riverbed roughness in the formation of sediment patches. Nelson provides a model for riverbeds with both bedrock and alluvial segments to determine how the texture of the riverbed and the presence or absence of sediment can impact river flow.
A recent article in Eos entitled, “Going Through a Rough Patch: Modeling Sediment Moving in Rivers,” highlights Nelson’s research encompassing both papers. Eos is the science news magazine published by the American Geophysical Union.
