Barchan dunes cruising dune-size obstacles
Geophysical 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 ...

Extending DUNE: The dune-xt modules
CoRR, 2016 Abstract: We present our effort to extend and complement the core modules of the Dis- tributed and Unified Numerics Environment DUNE (http://dune-project.org) by a well tested and structured collection of utilities and concepts. We describe key elements of our four modules dune-xt-common, dune-xt-grid, dune-xt-la and dune-xt-functions, which aim add ...

The Influence of Transport Stage on Preserved Fluvial Cross Strata
Geophysical Research Letters, 2022 Fluvial cross strata are depositional products of bedform migration that record formative flow and sediment transport conditions on planetary bodies. Bedform evolution varies with transport stage even under constant flow depths, but our understanding of ...

Aeolian Material Migration in Transbaikalia (Asian Russia)
Geosciences, 2019 We revealed regional features of functioning of a large Transbaikalian aeolian morphodynamic system. Natural pre-conditions, current realities and factors of development of aeolian processes are investigated.
