Hydrodynamic equation for a deposition model
(652K, Postscript)

ABSTRACT.  We show that the two-component system of hyperbolic 
conservation laws 
$\partial_t \rho + \partial_x (\rho u) 
=0 = \partial_t u + \partial_x \rho$ 
appears naturally in the formally computed hydrodynamic 
limit of some randomly growing interface models, 
and we study some properties of this system.
