IDES ONE-DIMENSIONAL INTERACTION 
The one-dimensional interaction of shock-waves, 
1307 
rarefaction waves, and contact-discontinuities (density alone 
discontinuous) can be conveniently discussed for water-like 
substances in the manner used by Courant and Friedrichs for 
ideal gases. 
in terms of the characterizing pressure-ratio F. 
Consider a plane shock-wave. 
One considers the change in material velocity 
Let V, be the material 
velocity of the normalized region and V the material velocity 
of the other one.
