Structural barriers to complete homogenization and wormholing in dissolving porous and fractured rocks
Tomasz Szawełło, Jeffrey D. Hyman, Peter K. Kang +1
Dissolution in porous media and fractured rocks alters both the chemical composition of the fluid and the physical properties of the solid. Depending on system conditions, reactive…
When barchan dunes move over craters
Paulo Vitor Ribeiro Plácido, Danilo da Silva Borges, Willian Righi Assis +1
We investigate the possible outcomes of a subaqueous barchan moving over a crater-like depression in the bed. For that, we carried out experiments where we varied the dune size, cr…
Barchans interacting with dune-size obstacles: details of the fluid flow and motion of grains
Nicolao Cerqueira Lima, Willian Righi Assis, Danilo da Silva Borges +1
We investigate details of the interaction of subaqueous barchans with dune-size obstacles by carrying out numerical simulations where the fluid is solved at the grain scale and the…
Evolving dunes under flow reversals: from an initial heap toward an inverted dune
Willian Righi Assis, Erick de Moraes Franklin, Nathalie Vriend
Sand dunes are ubiquitous in nature, and are found in abundance on Earth and other planetary environments. One of the most common types are crescent-shaped dunes known as barchans,…
On the effect of two-direction seasonal flows on barchans and the origin of occluded dunes
Willian Righi Assis, Danilo da Silva Borges, Erick de Moraes Franklin
We inquire into the morphodynamics of barchans under seasonal flows. For that, we carried out grain-scale numerical computations of a subaqueous barchan exposed to two-directional…
Field evidence for the initiation of isolated aeolian sand patches
P. Delorme, J. M. Nield, G. F. S. Wiggs +5
Sand patches are one of the precursors to early-stage protodunes and occur widely in both desert and coastal aeolian environments. Here we show field evidence of a mechanism to exp…
On the Connections Between Surficial Processes and Stratigraphy in River Deltas
Michael J. Puma, Rachata Muneepeerakul, Chris Paola +2
We explore connections between surficial deltaic processes (e.g. avulsion, deposition) and the stratigraphic record using a simple numerical model of delta-plain evolution, with th…
