Barchan dunes cruising dune-size obstacles

open access: yesGeophysical Research Letters, 2023
Abstract We investigate the behavior of subaqueous barchans reaching dune‐size obstacles by carrying out experiments where we varied the obstacle shape and size, the flow strength, and the grains' properties. We found that a subaqueous barchan can pass over or bypass a dune‐size obstacle, or even be blocked, with some intermediate ...
