It is used tu determine if an iteration loop needs to <br />be solved again or not. In this position is used to determine if the outer (return tlow) loop <br />needs to be iterated or not. <br /> <br />DoFinalSolutionStep [SOLUTION .MOD] <br /> <br />A tinal solution step may be required for either of two reasons. First, if there is a <br />Compact requirement for additional water from the Gunnison Basin, that requirement is met in <br />this version of the Planning Model by a special release from Blue Mesa Reservoir. Second, it <br />may be that either the inner or the outer iteration loop terminated (because the change was <br />within tolerance or because the iteration limit had been reached) after a moditication had been <br />made to the immediate return tlows or to operational releases. In this case the network would <br />be in an inconsistent state, where highs had been reduced helow the value currently stored in <br />the tlow parameter. If the network is in such an inconsistent state when the outer loop is <br />exited, the variable NeedToDistributeFlows in DoCram will cause a tlnal solution step to be <br />called. <br /> <br />DistributeReturnFlows [RTFLOW.MOD] <br /> <br />This is a CRAM library procedure to calculate and process return tlows which do not <br />return in the current model month. <br /> <br />DoEvapAccounting [ACCOUNTG .MOD] <br /> <br />This procedure does the necessary accounting of evaporation for Taylor Park and <br />Ridgway reservoirs. The evapuratiun accounting process differs signiticantly for the two <br />reservoirs. Taylor Park is relatively simple. because all water in the reservoir is divided into <br />three proprietary accounts. and the total physical evaporation from the reservoir can be <br />allocated directly among tbe three accounts in proportion to their end-of-month contents. <br />Ridgway is more complex because the proportionate allocation of total physical ~vaporation <br />extends to only four of the six accounts in the reservoir. These upper four accounts divide the <br />total physical evaporation in proportion to their respective contents, until they all are empty. <br />Thereafter, the Minimum Pool is charged for 100% of the evaporation until it is empty, and <br />then the Dead Storage Pool is charged for. 100% of evaporation. <br /> <br />CalcPower [POWER.MOD] <br /> <br />This is a CRAM library function to calculate the power generated by power plants <br />simulated in a network model. <br /> <br />OutputData [OUTPUT. MOD] <br /> <br />The is a CRAM lihrary function to write the results of the current month's simulation to <br />an output tile. <br /> <br />10 <br />
