A comparative assessment of AWBM and SimHyd for forested watersheds

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.
