copy documentation will follow. In August, we began working on documenting the code
for the CU model.

3.62 Users' Manual

The on-line documentation will be used to create a hard-copy user manual. The Users'
Manual will include an introduction, tutorial, detailed reference guide for the GUI,
technical background, glossary of terms, and an index. The introduction will illustrate
the consumptive use model's role in the bigger picture of CRDSS and will provide
information about the context and scope of the model. The tutorial will run through a
scenario for using the Model. The scenario will be technically robust and will include
realistic data. The detailed reference guide will comprise the bulk of the manual and will
describe each possible selection of the GUI. A section will be included with the technical
background of the model including a literature review for the ET method selected and
the assumptions used.

The User Manual will not directly duplicate information found in the on-line
documentation, but there will definitely be overlap in the development. The tone of the
writing will be geared to the hard copy format and screen grabs showing actions will be
included along with other informative graphics.

3.6.3 Developers' Manual

The Developers' Manual will be targeted at the more sophisticated users of the system.
This will provide detailed technical and programming information and will also contain
a glossary, index, and a list of source code. Other features will include a listing and
definitions of each of the variables and routines used in the model. A list of event call-
backs with a flow chart will also be included.

5.0 Conclusions and Recommendations

The CU model is progressing according to schedule. In the next few weeks as the model's
numerical and GUI components will be ready to be tested and more emphasis will be devoted
to the data compilation, calibration of the models, and verification of the results.
