<br />HEC-l INPUT DESCRIPTION <br />JOB TYPE OPTION (J Cards) <br /> <br />3.3 JD CARD - DEPTH/AREA STORM <br /> <br />Required only if stream system is to be simulated using a consistent <br />depth/area relationship. Each JD card is followed by a set of PC or PI <br />cards giving the precipitation pattern to be used for that depth and area. <br />If no pattern is given following any of the second through ninth JD cards, <br />the previous pattern will be used. <br /> <br />. <br /> <br />Precipitation patterns may be generated using the hypothetical storm <br />option. PH cards are used in place of PI or PC cards. A new storm <br />pattern is generated for each area given on the JD cards. <br /> <br />FIELD VARIABLE VALUE DESCRIPTION <br />Col 1+2 ID JD Card identification. <br />1 STRM(l) + Average precipitation in inches (mm). <br />2 TRDA(l) + Area in square miles (sq km). <br />3 STRM(2) + Same as above for up to a total of 5 pairs <br /> of depth/area values. <br />4 TRDA(2) + Same as above for up to a total of 5 pairs <br /> of depth/area values. <br /> <br />, <br /> <br />. <br /> <br />Page 14 <br />
