Oft 111'1100".11 <br />This program provides a statistical analysis of simulated water quality data at <br />a point. Eleven parameters including flow are analyzed for their mean and <br />standard deviation, and their minimlllll and maximlllll values. If observed data are <br />available, the mean error of reproduction and its standard deviation are <br />evaluated. If water quality standards are available, the number of simulated <br />valu~s and the percent of time that they exceed the standards are tabulated. <br />This program is intended to analyze and summarize the output results from the <br />Stream Water Oualitv nroaram. <br />8. ,.ROORAIIIIN:CIII'ICATIOMI <br />The program is written in FORTRAN IV. <br />c. ..T HODS <br />The program uses standard statistical metnods to calculate means and standard <br />deviations. The error term is defined as the simulated value minus the <br />observed value. <br />D. .QU'~."T DeTAILS <br />The program is operational on CDC 7600 and UNIVAC 1108 but may be used on <br />other equipment with minor modification. The program requires 9K words of <br />storage on the CDC 7600. <br />... IN",p <br />The program reads binary data from a magnetic tape having 11 water quality <br />parameters for up to lUU stream station locations in an unlimited time series. <br />'0 ADDITIONAL .....ARK. <br /> <br />DIG .011111 <br />t AUO 6D <br /> <br />2883 <br /> <br />.......OU. .DlTIONa .111.
