Abstract

Mobile dunes threaten infrastructure in hyper-arid regions. Meanwhile, moisture retention can slow their advance. With the assistance of Dr. Renee Richer, we conducted field work in Qatar to elucidate the wind flow around crescent-shaped ‘barchan’ dunes, and we deployed unique capacitance probes to record their exchange of moisture with the atmospheric boundary layer.

BIO

Michel Louge has taught at Cornell University since 1985. His work focuses on granular and gas-solid flows with geophysical and industrial applications. His group has conducted laboratory and field experiments, created numerical simulations, modeled fluid mechanics and heat transfer in these flows, and developed new instrumentation.
