Downstream-migrating fluvial point bars in the rock record

M Ghinassi, A Ielpi, M Aldinucci, M Fustic - Sedimentary Geology, 2016 - Elsevier
Classical models developed for ancient fluvial point bars are based on the assumption that
meander bends invariably increase their radius as meander-bend apices migrate in a …

A comparison of standard k–ε and realizable k–ε turbulence models in curved and confluent channels

R Shaheed, A Mohammadian… - Environmental Fluid …, 2019 - Springer
Bends and confluences are often observed in rivers, and one of the phenomena that
