timing.

Based on the user scenarios and a review of the available models a set of
generic functional models were developed, These are listed in the following
section.

River Basin Simulation

Scenario Reference: Annual Operations Planning

Functional Specifications:

. Monthly time step.

. Variable time span (horizon) from two months to several years,

. Simulate power generation.

. Policy is modifiable (rule curves, demand. law of the river).

. Accepts historical, synthetic and forecasted hydrologic inputs.

. Different system configurations are easy to build and modify, The
aggregation/disaggregation of the diversion nodes is allowed,

. Input/output of multiple runs is handled automatically through a
data base,

. May handle water rights,
. May handle water quality (salt, mass balance).

Water Rights Operations

Scenario Reference: Water Rights Administration 2.4. 3,7
Functional Specifications:
. Allocates natural flow which is determined by flow paI1itioning (or
forecasted) model.
. Daily time step,
. Variable spatial scale.
. Allocation is based on prior appropriation water rights,
. Handle all water rights in the basin.
. Handle selected e)(change operations. augmentation plans, and
regervoir operations"ana,ditch diversions.
. Account for riyer gains or losses (user or adminisrralOr supplied),
