The interval length and starting time for the first <br />interval will be as specified on the last IN card which has been read. <br />The program reads all consecutive PI cards and interpolates incremental <br />precipitation values for the computation time interval and time period <br />specified on the IT card. <br /> <br />~ <br /> <br />FIELD VARIABLE <br /> <br />VALUE <br /> <br />DESCRIPTION <br /> <br />Col 1+2 ID <br /> <br />PI <br /> <br />Card identification. <br /> <br />1 PRCPR(l) <br /> <br />+ <br /> <br />Precipitation in inches (mm) in first <br />interval. <br /> <br />2 PRCPR(2) <br /> <br />+ <br /> <br />Etc. <br /> <br />l2.l.3 PC CARD - CUMULATIVE PRECIPITATION TIME SERIES <br /> <br />PC cards contain a cumulative precipitation distribution. They are <br />only used after a PG, PB or JD card which identifies the distribution. <br />The interval of ordinates and time of first mass curve ordinate are as <br />specified on previous IN card. The program reads all consecutive PC cards <br />and interpolates incremental precipitation values for the computation time <br />interval and time period specified on the IT card. <br /> <br /> FIELD VARIABLE VALUE DESCRIPTION <br /> Col 1+2 ID PC Card identification. <br /> 1 PRCPR(l) + First ordinate of precipi ta tion mass curve <br />'; in inches (mm). <br /> 2 PRCPR(2) + Etc. <br />, <br /> <br />Page 49 <br />
