<br />When the pool elevation falls belOw the top of the flood. control <br />pool a release is made which is halfway between the current period's <br />inflow and the previous period.' s release, but not less than "CHCAP". <br />If the calculated release exceeds the freeflow discharge of the spill- <br />way and conduit, the gates are fully opened and the routing is made in <br />a manner similar to that described in Step No.8. The releases shown <br />in Table 2 show the criteria used for each "case" in the printout. <br /> <br />. <br /> <br />step 10 - After the spillway rating and flood. routing have been <br />ccmpleted, a new "run" is made if desired. <br /> <br />5. INPUT <br /> <br />a. Since this program has been written in Fortran the input data <br />must be in certain columns on specific cards. All the data are read <br />using ten numbers per card and eight spaces on the card are reserved <br />for each number except that column 1 on all cards is reserved for the <br />alphanumeric character (A-H) showing the type of card. The arrangment <br />of the variable on various cards is described in Exhibit 8 and is <br />shown on Exhibit 9. <br /> <br />b. Table cards. Standard table cards are required just before <br />the first 5 heading cards for only the first run. The table cards <br />are used to initialize array values. The values of "HDHE, HEHD, CC, <br />EC, ZKP, HDDHE, IS, and ZKA" (both concrete and earth arrays) requir- <br />ing 39' cards are required for the Part I (Spillway Rating). The value <br />of "IPERSR" and "IPERDQ" requiring 2 cards must be used for the Part II <br />(Flood. Routing). For the 1 large program all 41 cards are used before <br />the five heading cards. Exhibit 4 shows these standard cards. <br /> <br />6. OtlTPIJ'l' <br /> <br />a. The output for the test runs is shown in Exhibit 5 ,and discussed <br />in paragraph 9. <br /> <br />b. Most of the input to the program is punched out for a permanent <br />record of the assumptions used in the program such as the 5 heading' <br />cards and the cards describing the rating and the routing. A <br />table is punched out snowing elevation versus capacity, spillway free- <br />flow, spillway tailwater, submerged spillway discharge, conduit <br />discharge freeflow, conduit tailwater, submerged conduit discharge, <br />total discharge spillway and conduit and assumed discharge for Modified <br />PuIs routing. <br /> <br />c. The routing for the gate schedule curve operation is described <br />by punching out time, Inflow, Outflow, storage on induced surcharge <br />envelope curve, storage available assumed and computed, Reservoir <br />capacity in acre feet, pool elevation and the criteria for making the <br />release ("ICASE"). <br /> <br />13 <br />
