DOI: 10.1029/2019gl085910
Abstract: Fluvial cross strata are an archive of ancient river morphodynamics. Controls on their preservation are well documented for bedforms equilibrated with prevailing flows; however, variability in water and sediment discharge results in bedforms that are… read more here.

DOI: 10.1029/2024gl109622
Abstract: River bedforms and their deposits—fluvial cross strata— respond to floods. However, it is unclear if all floods are equally represented in cross strata. Here, using a series of physical experiments in which bedforms were subjected… read more here.

DOI: 10.1111/sed.12855
Abstract: Although virtual outcrops or digital outcrop model applications in geological studies are becoming increasingly common, virtually no attention has been given to acquisition of palaeocurrent data from cross‐strata. Palaeocurrent indicators are abundant in the sedimentary… read more here.
