slope limiter. The location of the hydraulic jump is predicted accurately
and the ow rate is well conserved except at the jump. The Roe ux per-
forms better than the HLL ux within the jump. Overall, the numerical
results are satisfactory.
4.5.5 Flow over irregular bed
In this test, transcritical ow in a channel with an irregular, friction-
less bed is simulated. The bed elevation is given in Table4.2 (Goutal and
Maurel, 1997). The initial conditions consist of a water surface elevation
of 16 m with zero velocity. The ow rate at the inow section is set to
50 m
