The present work examines the temporal evolution of dune number density in desert
barchan dune fields and the effects of wind velocity, particle diameter and sand supply …

Collision among barchan dunes is a main cause for the dune swarm to achieve size and
speed selection, and it can be divided into two patterns: coalescence and ejection. Here, a …

Tidal sand waves are rhythmic bedforms found on sandy continental shelves that pose a
threat to offshore activities. While emphasis is placed on studying their natural …

The soft part of the Earth's surface–the ground beneath our feet–constitutes the basis for life
and natural resources, yet a general physical understanding of the ground is still lacking. In …

Dunes are bedforms of different size and shape, appearing throughout aeolian, subaqueous
and extra-terrestrial environments. Collisions between dunes drive dune field evolution, and …

This literature review is written as part of my PhD project, which is in turn part of the NWO-
funded “OR ELSE” project. This project investigates and aims to improve marine sand …

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 …

In landscape‐scale experiments at the edge of the Gobi desert, we show that various dune
types develop simultaneously under natural wind conditions. Using 4 years of high …
