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 ...

Seasonal Variation of Catenary-Bead Dunes in the Yangtze River Estuary: Causes and Implications
Journal of Marine Science and Engineering, 2022 Low-angle lee-side slopes of dunes are commonly developed on the world’s riverbeds, and dune migration associated with sediment transport exert a major influence on riverine processes.

Mechanisms of Dune Growth and Decay in Rivers
Geophysical Research Letters, 2021 The mechanisms responsible for dune growth and decay remain a major unknown in river dynamics. Two theories have been supported by experiments and numerical models. A hydrodynamic explanation suggests that growth and decay occur due to phase lags between

Journal of Maps, 2021 The article presents changes in the topography of the Toruń area due to the degradation of dunes by human activity, and a reconstruction of their earlier location and morphology.

Science, 2018 Methane ice dunes on Pluto Wind-blown sand or ice dunes are known on Earth, Mars, Venus, Titan, and comet 67P/Churyumov-Gerasimenko. Telfer et al. used images taken by the New Horizons spacecraft to identify dunes in the Sputnik Planitia region on Pluto (see the Perspective by Hayes).

Inferring Airflow Across Martian Dunes From Ripple Patterns and Dynamics
Frontiers in Earth Science, 2021 Large ripples form striking patterns on the slopes of martian sand dunes which can be mapped and tracked using high-resolution optical images. The ripples vary in orientation, wavelength, plan-view morphology, and rates of migration.
