Dynamic Evaluation of Barchans in Band-e-Rig Kashan in the Period 2013 to 2019 [PDF]

open access: yesکاوش‌های جغرافیایی مناطق بیابانی, 2022
IntroductionWind erosion and the formation of sand dunes are common phenomena in many arid regions around the world. More than 100 types of sand dunes have been classified by geomorphologists based on shape and size criteria (Lancaster, 1995). One of the

UAV-SfM based field quantification of barchan dune celerity and morphodynamics in Gonghe Basin [PDF]

open access: yes
Barchan dunes do not often coexist with grasslands. However, in Gonghe Basin, north-eastern part in Qinghai-Tibetan Plateau (QTP), China, many barchan dunes are distributed on the grassland at high altitude.

An experimental investigation of 3D subaqueous barchan dunes and their morphodynamic processes [PDF]

open access: yes, 2020
In order to experimentally investigate the flow dynamics around a 3D barchan dune, herein we adopt a new experimental approach that enables us to quantify flow around complex morphologies using a refractive index matching (RIM) flume.

Scour Pits in the Medusae Fossae Formation and Olympus Mons Region on Mars

open access: yesJournal of Geophysical Research: Planets, Volume 130, Issue 7, July 2025.
Abstract The Medusae Fossae Formation (MFF) covers a region of Mars located to the southwest of the Olympus Mons shield volcano. The nature of this formation has been under debate for over 30 years. In order to better understand the MFF, we investigated scour pits or V‐shaped depressions carved into many places across the MFF.

Morphology of Barchan Dunes on Earth and Mars:Classification and Scale-Invariance [PDF]

open access: yes
Morphological characteristics were measured for barchan dunes on Earth (2,686 dunes in 30 barchan fields) and Mars (720 dunes in 10 barchan fields) using satellite images. The data were used to (a) develop a new barchan classification system; (b) compare

Multidirectional Dune Dynamics Under Seasonal Winds on Mars

open access: yesGeophysical Research Letters, Volume 52, Issue 12, 28 June 2025.
Abstract We present a systematic assessment of the complex aeolian bedforms across the western rim of Hellas Planitia, the largest impact basin on Mars. Repeat orbital imaging shows crescentic, transverse, and star dunes across the Hellespontus Montes region migrate, converge, and occasionally reverse course.

Barchan morphometry: examples from Earth and Mars

open access: yes, 2019
Electronic Thesis or DissertationBarchans are a common sand dune type found on both terrestrial and Martian surfaces. The morphometry of individual barchans and barchan groups has been measured extensively in past studies. Within each dune field, similar
