Description

This dataset contains experimental videos and related metadata associated with the study "When barchan dunes move over craters". The experiments were conducted in a controlled water channel, where subaqueous barchan dunes composed of granular particles migrate and interact with fixed craters of varying diameters. The videos document different interaction regimes, including trapping, fragmentation, and overpassing, providing direct visualization of dune–crater dynamics.
