is used in the simulation. The cases of sudden removal of
the dam and a partial dam break with a 0.7315 m (2.4 ft) wide breach are
considered in this test.
The simulated hydrographs at the locations shown in Figure5.7 are
compared with the available measured data. For the fully breached case,
the simulated and measured hydrographs at P1 (39.624 m upstream of
the dam) and P4 (5.7912 m upstream of the dam) are shown in Figure5.8,
while the hydrographs at P5 (7.62 m downstream of dam) and P6 (45.72
m downstream of dam) are shown in Figure5.9. For the partial dam-
