This:
h(t)=h(o)=exp(-RRPgt/2Dn)
This equation has cropped up to describe the rebound of land after an Ice sheet has been removed.
h(t) is the height after a time, t, has elapsed.
h(o) is the initial height
R is the radius of the depression/icesheet.
P is the density of the asthenosphere/rock.
g is the acceleration of gravity at earth's surface.
n is viscosity.
I don't know what D is though, and when I am rearranging to solve for viscosity this means I have a term of D left over in my answer.
I tried rearranging for its units and I get Metres Seconds; what does this represent?
edit: I think my previous assertion was spurious and that the units should be metres, so it must represent a depth. If anyone could explain this to me, that'd be good though.
