With default parameter values for
AWBM and SimHyd, and
max. retention value of 105mm
for the SCS Curve Number method,
all models show a non-linear
relationship between rain excess
NB: All the ‘stores’ in AWBM and
SimHyd were assumed to be half
- watersheds applied
- models developed
There is a much larger difference
between watersheds than between models!!

Both precipitation and streamflow have
significantly decreased over the 39 year period.
