<br />~ <br /> <br />19. TITLE CARDS <br /> <br />TT: Title Card. The title cards are used to identify the unique <br />features of a particular job so as to jog one's memory when the output <br />is encountered at some later time. Useful items to note on these cards <br />are the run date, data bases, items modified from the last job, different <br />operation mode or design feature for one or more flood plain management <br />plans, etc. Sometimes it is convenient to adopt a sequential numbering <br />system for each job run during a particular study. As many TT cards may <br />be input as desired. Although these cards are usually input at the <br />beginning of the job, they may be inserted before reach or plan data to <br />annotate the features of the input data. <br /> <br />20. JOB CARDS <br /> <br />These cards input data and activate analysis procedures that will <br />apply throughout the job. Note that two cards, CN and PN, are required <br />cards and must be provided for each different job. <br /> <br />Jl: First Job Card. This optional card need only be provided when <br />a period analysis is desired. A positive value for IPOAactivates the <br />economic routines which compute equivalent annual damage by applying the <br />input discount rates (J2 card) to compute present worth and to amortize <br />the results over a period of analysis. It should be noted that unless <br />any of the input data are varied by time (input data years), the expected <br />annual damage will be the same for each year and equal to the equivalent <br />annual damage. The study year (ISTDYR) references the year that represents <br />existing conditions. If an~ of the input parameters are referenced to a <br />year before and after the study year, the Particular parameter values will <br />be found by interpolation. The base year (IBASYR) identifies the first <br />year that the plan is expected to be operational. As the hydrologic, <br />hydraulic and economic conditions are assumed to represent end-of-year <br />values, the expected annual damage computed for the base year is discounted <br />one year to the beginning of the period of analysis. . IDOLYR conveys the <br />month and year to which the economic data are referenced and is only used <br />for information purposes on the output. NHIS defines the number of input <br />data years that represent historic years (prior to the study year). The <br />expected annual damage for these years will be output with the period of <br />analysis results, but do not impact on the equivalent annual damage <br />computations. <br /> <br />J2: Second Job Card. This card is used to input the discount rates <br />for a period analysis with one or more flood plain management plans. This <br />card would only be provided if IPOA on the Jl card is positive. The first <br />discount rate is treated as the primary rate and is included in the detailed <br />output. The results for the other optional, or trial, discount rates are <br />only included in the job summary output. <br /> <br />13 <br />
