<br />HEC-l INPUT DESCRIPTION <br />OPTIMIZATION OPTION (0 Cards) <br /> <br />4.3 OS CARD - FLOOD CONTROL SYSTEM OPTIMIZATION <br /> <br />When HEC-l is used to determine optimal sizes of flood control system <br />components, initial estimates for sizes of the components are entered on <br />the OS card. The following cards are used later in the input deck to <br />refer to variables initialized on the OS card - <br /> <br />~ <br /> <br />DO <br />SO <br />WO <br />LO <br /> <br />Diversion <br />Reservoir <br />Pump <br />Local protection projects and <br />uniform degree of protection <br /> <br />FIELD VARIABLE <br /> <br />VALUE <br /> <br />DESCRIPTION <br /> <br />Col 1+2 ID <br /> <br />OS <br /> <br />Card identification. <br /> <br />1 VAR(l) <br /> <br />+ <br /> <br />Size of flood control system component. <br />Reservoir volume in acre-ft (1000 cu m), <br />diversion, and pump in cfs (cu m/sec), local <br />protection in cfs (cu mVsec) or feet <br />(meters), uniform degree of protection in <br />percent. Size will not be optimized. <br /> <br />Initial estimates of component; size will be <br />optimized. <br /> <br />2-10 VAR(I) <br /> <br />+,- <br /> <br />Similar to Field 1. Up to 10 values. <br /> <br />, <br /> <br />Page 16 <br />
