This work is part of my PhD and details the shape of dunes in the world’s big rivers. Here, I show that the shape of dunes in these rivers is flatter and smaller than previously thought. This work was recently published in Nature Geoscience.

“Before Julia Cisneros started working toward her PhD in geology at the University of Illinois, our understanding of sand dunes on the bed of large rivers was limited, and based largely upon observations in small rivers and laboratory experiments.”https://las.illinois.edu/news/2020-03-04/exploring-workings-waterways
