Although the attenuation is larger when the starting level is 592.7 metres, it is not significantly larger - for example - case la), 100 year return period flood is discharged as 560 m 3 /s when the starting level is 592.7, compared with 618 m3/s in Table 13.

All discharges are in m 3 /s. It serves to illustrate the rapid increase in level water as a flood passes. In this caSe it rises 2.1 metres in 4 hours. For the 100 year return period flood, it rises 3.3 metres in 4 hours. (m)
