2. The work involved in actually modifying and calibrating the model
would be a minor part of the consultant's task compared with the work
required to develop the necessary water requirements, efficiency, and
return flow data for the individual water users in this example.

Step-by-Step Description of Session No.3

A. Steps proposed by Mike Gross:
1. Locate area to be enlarged (to add detail).

2. Describe enlarged system as arcs, links, nodes, according to
consultant's recommendation.

3. Select "add/modify demand. "

4. Select "add new arcs/links. "

5. -Type in characteristics of new system:

*

diversion demand amount and priority (may be
aggregated summations of rights, but respect
need for division of aggregated groups so as
not to span a major calling demand
downstream, e.g. Redlands, UVWUA, Black
Canyon. Curecanti).

*

depletion as % of diversion made.

*

return flow point.

6. Run against baseline and known hydrology; calibrate by adjustment of
diversion/return/lag /efficlency.

B. Steps proposed by Randy Seaholm:

1.

Select Edit.

2.a. Select Baseline.

b. Select Hydrology.

3. Select a Network Building Option

*

Add diversion for each water right in that
specific stream reach.

*

How many return flow arcs can you add?

4... Basically see this as an extension of Session 1 from this point on. Just
additional iterations,
