Emergence of a Barchan Belt in a Unidirectional Flow: Experiment and Numerical Simulation
Atsunari Katsuki, Macoto Kikuchi, Noritaka Endo
We observed time evolution of dune fields in a water tank experiment and simulated it by using a simple model without taking complex fluid dynamics into account. The initial sand b…

Collision dynamics of two barchan dunes simulated by a simple model
Atsunari Katsuki, Hiraku Nishimori, Noritaka Endo +1
The collision processes of two crescentic dunes called barchans are systematically studied using a simple computer simulation model. The simulated processes, coalescence, ejection…
