" Task 1.14(a) - Evaluation of Consumptive Use Models

Phvsical Characteristics Database
The Physical Characteristics Database will store "static" attribute data.

Station and UseT Databases
These Databases will store infonnation about the users of the CRDSS and geneTal
infonnation about weather stations such as reliability of data and contacts for obtaining
data.

Scenario Database
We are assuming the Consumptive Use model will be generating some of its own
"data" in the form of "what if' scenarios and modeling, These data may be more
efficiently stored outside the model and a consistent process for handling the generation of
scenarios should be developed,

1.3 Unit Types for Data
Representation of units will be a majoT factor in detennining the quality and ease-of -
use for the system. There are often different choices of units for any given data field.
Sometimes the source of the data will determine the units for data storage, but the user
may define how those units are expressed in the interface. Therefore, in this document the
unit-less quantity names will be used and some standard unit types will be anticipated for
the expression of the quantities.

2.0 Baseline Scenario Data

When the user accesses the model he/she will be presented with information that will be
stored as a baseline scenario and will be asked to specify certain parameters needed to
estimated consumptive use. These values may be used as default values or altered by user
input and will specify which data the DMI returns to the CU model.
