0.1 and 22.8, mean is 10.6 m3 /s. Surface slope values are
between 1.2% and 29.3% with 14.5% mean value. Recall from
Table 5, catchment 530 has the higher CN value, since it
mainly has least permeability. Depending on the fact that,
the lower the concentration time, the more the hazards in
the runoff (Dawod et al., 2011), catchment 530 may be considered
as the most hazardous catchment.
