Gravity Currents in Aquatic Canopies
Published 2012“…As canopy drag increases, the propagating front varies from the classic profile of an unobstructed gravity current to a triangular profile. Unlike the unobstructed lock exchange, the gravity current in the canopy decelerates with time as the front lengthens. …”

Gravity currents in a porous medium at an inclined plane
Published 2006“…We consider the case where the volume of the resulting gravity current increases with time like tα and show that for α < 3 at short times the current spreads axisymmetrically, with radius r ∼ t(α+1)/4, while at long times it spreads predominantly downslope. …”
