The role of discharge variability in the formation and preservation of alluvial sediment bodies

CR Fielding, J Alexander, JP Allen - Sedimentary Geology, 2018 - Elsevier
Extant, planform-based facies models for alluvial deposits are not fully fit for purpose,
because they over-emphasise plan form whereas there is little in the alluvial rock record that …

How do big rivers come to be different?

PJ Ashworth, J Lewin - Earth-Science Reviews, 2012 - Elsevier
Big rivers dominate the world's continental surface, yet we are still learning about how they
operate and whether they are explicably different, not only from each other, but also from …
