Experiments on Mixing in Gravity Currents – Diana Sher

I will present a series of new laboratory experiments, using dye attenuation imaging, to measure the mixing in a turbulent gravity current. Results are applied to interpret the hazards associated with a large release of dense gas.

Characterisation of Flux Sensitivity to Uncertainty in Porous Media – Alex Evans

Uncertainty in estimates of rock permeability leads to uncertainty in estimates of derived flow quantities. I will present an approach to efficiently quantify the uncertainty of flux estimates as a function of permeability uncertainty. I will also highlight how estimates of flux uncertainty are sensitive to the model used to represent the permeability field.
