# Viscous Burgers equation physical meaning

The viscous Burgers' equation: $$q_{t}+q\:q_{x}~=~\nu\:q_{xx}, \mbox{ where } \:\:\nu >0,$$ combines the nonlinear propagation of $q(x,t)$ and the diffusion.

• What is this equation for? (in modelling context)

• What is so special about it? (other than if $\nu=0$ then the solution can form a shockwave)
