Example 3 in Fig.

is a 1D dry bed dam-break type problem, with a negative
1.0 m bed step. The solution presents a left-moving rarefaction wave, a stationary
shock at the step and right-moving wetting advancing front. Again, the presence of
the step leads to a reduction of the discharge to the right side of the domain, induced
by the head loss in the stationary shock. The position of the fan expansion and the
shock remains correct, and no numerical oscillations are produced.
