SUMMARY:Climate change and the storage of carbon dioxide gas in topographi
 cally varying conduits - Prof. Herbert Huppert (DAMTP\, University of Camb
 ridge)

DESCRIPTION:Climate change is already causing considerable concerns\, incl
 uding resultant flooding\, structural damage to buildings\, amongst other 
 problematic situations. One way of reducing the amount of carbon dioxide r
 eleased into the atmosphere is to store it deep underground\, where it is 
 in a supercritical (liquid-like) state and can spread in a conduit capped 
 by an impermeable surface. Quite some work has been carried out on this id
 ea at Slipner off Norway and during the Ottway project in Victoria\, Austr
 alia\, as well as elsewhere around the world.  Theoretrical valuations of 
 such flows have so far only really considered  how this liquid-like materi
 al is sequestered in layers with opaque upper and lower horizontal boundar
 ies. We will present new results of fluid flow over topographically varyin
 g boundaries\, incorporating uniform drainage and localized leakage.
