<br />DuC209 <br /> <br />Stochastically-derived and other data may also be used if provided to the model in the same <br />format. <br /> <br />Demand Data <br /> <br />The model will utilize demand and salt information for each demand point. Data to be <br />specified includes the monthly withdrawals and depletions ( or annual values and the monthly <br />distributions) and the concentration of salt for the return flows, It will be possible to enter data <br />only for specific years and then interpolate the intervening years (either held constant or linearly <br />trended). The data will be available in an ASCII format. <br /> <br />Operating Rule Data <br /> <br />The user will have the ability to provide input data for use by the rules (such as target elevations <br />for each month). In addition, a mechanism will be provided to defIne computed data that is <br />required for rule processing, <br /> <br />4 Analysis Tools <br /> <br />The model should provide a set of flexible tools to summarize and inspect the results of the <br />model, to analyze these results, and to track the model's performance, All state and decision <br />variables should be readily accessible, It is noted, however, that the BOR implementation of the <br />model (as a model resident to the BOR's DSS, Reference 1) will provide some analysis functions <br />(such as statistical analysis) through the DSS and will not necessarily be available in a <br />standalone version of the model. <br /> <br />Functions will be provided to specify computation and reporting of aggregated variables, These <br />might include basin-wide reports of consumptive use, energy generation, water in storage, etc, <br /> <br />Both graphical and text-based output will be provided. We invite comments with regard to <br />usefulness of the current CRSS output. <br /> <br />Some methodology to analyze and display multi-objective trade-offs will be explored. We <br />envision this to be based on the use of multiple runs under varying operating assumptions and <br />conditions. <br /> <br />5 Verification and Validation <br /> <br />Our approach to verifIcation and validation will be centered around the example problem and test <br />scenarios that we develop with the user community to aid the design and development processes. <br /> <br />We plan model testing throughout the development and implementation stages of the project. <br />For instance, we will initially verify that the model methods behave as expected, especially with <br />regard to mass balance. <br /> <br />II <br /> <br />DRAFT: February 17, 1994 <br />
