• Prepared By: Riverside Technology inc.

Task Memoranda 1.14-04 and 1.14-05 were prepared detailing the results of each model.
?
Subtask 5: Develop the CU Model Methodologies

The analysis and verification of agricultural consumptive use as calculated by XCONS2 was
?
completed.

The USBR reservoir evaporation procedures were reviewed.
?

Task Memorandum 1.14-01 summarizing CU model methodologies was written.
?
Subtask 6: Identify the Data Needs of the CU Model
Core and fringe data requirements for databases were identified.
?

The CU data input requirements document (Task Memorandum 1.14-2) was written to
?
document the projected input requirements.
?
Subtask 7: Write Task Memoranda Describing the Process and Define the Work Plan for Phase IIa
A time-line was created along with a detailed work plan for phase I. These documents identify
?
subtasks that support the goals outlined in Exhibit A: Scope of Services Year I.

Dates and responsibilities were identified in the work plan for when software and hardware
?
should be in place to coordinate with other activities.
Phase II (May-December 1994)
Subtask 1: Develop Design for CU Model
A preliminary design for the overall program for the CU model was developed.
?

The USBR XCONS2 program was studied in depth. It was determined that the structure of the
?
program needed to be modified to conform with a more structured programming approach
(modular and documented).

A study of the SMB model was completed, and the subroutines that needed to be included in
?
the overall CU model were identified.

A comprehensive listing of data needed by the CU model was submitted on June 2. This
?
document was a revised version of Task Memorandum 1.14-2 and was to be used to develop
low-level data management interfaces (DMIs) needed to retrieve information from the database.

The first design of the functionality of the graphical user interface (GUI) was developed on
?
paper.

The draft output files were given to the State for comments.
