If this is an <br />optimization job (OU card supplied), this <br />variable will be fixed at this value and not <br />optimized. <br /> <br />-1 For optimization only (OU card previously <br />supplied), program will assum.e a starting <br />value and then optimize. <br /> <br />2 <br /> <br />GIA <br /> <br />0,+ <br />or - <br /> <br />3 <br /> <br />0,+ <br />or - <br /> <br />SAI <br /> <br />4 <br /> <br />0,+ <br />or - <br /> <br />BEXP <br /> <br />5 <br /> <br />RTIMP <br /> <br />+ <br /> <br />, <br /> <br />6-10 <br /> <br />;: <br /> <br />Same as (-1) above except program uses this <br />value (after sign change) as the starting <br />point for the optimization. <br /> <br />Infiltration rate in inches/hour per <br />(inch**BEXP) or mm/hr per (mmm***BEXP) of <br />available soil moisture storage capacity <br />(i.e., 1 - soil moisture). See field 1 for <br />meaning of VALUE. <br /> <br />Initial value of SA avaiable soil <br />moisture capacity in inches (mm). See Field <br />1 for meaning of VALUE. <br /> <br />Exponent of available soil moisture <br />storage, SA. Default value is 1.4. ~ee <br />Field 1 for meaning of VALUE. <br /> <br />Percent of drainage basin that is <br />impervious. No losses are computed for <br />portion of the basin. This variable is <br />optimized. <br /> <br />this <br />not <br /> <br />Repeat Fields 1-5 for second kinematic <br />subcatchment if used. <br /> <br />Page -41 <br />
