(Young et al, 1995, Borah and Bera, 2003), urban stormwater models e.g.
models such as STORM, SWMM, and DR3 (Singh & Woolhiser, 2002) or
because of requirements for large amounts of data (e.g. MIKE SHE–Bouraoui &
Dillaha, 2000 and Borah and Bera, 2003).
Based upon the results of this screening assessment against the selection
criteria, five models were selected for further review because they appeared to
fulfill all of the attributes needed for the study. These were the;
• Australian Water Balance Model-2002 (AWBM-2002)
• Simulator for Water Resources in Rural Basins (SWRRB)
• Areal Nonpoint Sources Watershed Environment Response Simulation
Model (ANSWERS 2000)
• Soil Water Assessment Tool (SWAT) and
• Agricultural Catchments Research Unit Model (ACRU)
3.3.1 Australian Water Balance Model-2002 (AWBM-2002)
During further screening for this model it was discovered that the AWBM-2002
(Australian Water Balance Model) theory manual (Boughton, 2002) was
unavailable from the model’s website for detailed process analysis to be
undertaken. Communication with the author of the AWBM calibration and
operation manual 6 Boughton, W., informed the writer 7 that the theory manual
was under development and yet to be published. This therefore ruled out the
use of AWBM because, even though by the description of AWBM-2002 in
Boughton (2002, 2003) in the calibration and operating manual the model fulfils
the minimum criteria for the choice of a model for this study, details of methods
and detailed data requirements used to compute the various processes e.g.
