Bank pull or bar push: What drives scroll-bar formation in meandering rivers? (2014)
Journal Article
van de Lageweg, W. I., van Dijk, W. M., Baar, A. W., Rutten, J., & Kleinhans, M. G. (2014). Bank pull or bar push: What drives scroll-bar formation in meandering rivers?. Geology, 42(4), 319-322. https://doi.org/10.1130/G35192.1

One of the most striking features of meandering rivers are quasi-regular ridges of the point bar, evidence of a pulsed lateral migration of meander bends. Scroll bars formed on the inner bend are preserved on the point-bar surface as a series of ridg... Read More about Bank pull or bar push: What drives scroll-bar formation in meandering rivers?.
