Sand storms (and also sea breezes) are examples of buoyancy driven gravity currents in the atmosphere. Of particular interest is how ground friction affects speed of propagation and mixing in gravity currents.

Plumes in density stratified flow above a city can impact air quality.

Such plumes can be studied in the lab.

Dispersion of pollution in and above cities is being studied via lab experiments on model cities.

Buoyant river outflows influence the health of the coastal ecosystem.

Schematic of the turntable experiments shown above is helping to unentangle the dynamics of river outflows.

River outflows transport nitrates to Lake Erie. This can result in algal blooms.

Environmental pollution is mitigated by mixing. Details of the physics of mixing between fluids of different densities are being studied via lab experiments.
