If the flow can vary from <br />supercritical to subcritical or subcritical to <br />supercritical with time and location along the <br />routing reach, KSUPC z 2, 3 or 4, If KSUPC - 2, <br />the hydraulic jumps can move upstream or <br />downstream. If KSUPC c 3, the hydraulic jumps move <br />only if the Froude number exceeds 2.0. (This <br />increases the numerical robustness). If KSUPC = 4, <br />the hydraulic jumps can never move. If the flow is <br />nearly critical along several adjacent reaches, <br />KSUPC c 3 or 4 should be specified since these <br />options are more robust (numerically) and this is <br />needed for near-critical flow. <br />Parameter denoting the total number of lateral inflow <br />hydrographs along the downstream channel-valley; a <br />maximum of 12 hydrographs, each with a maxim'~ of <br />100 ordinates, are allowed. <br />Number of ordinates in spillway gate control curve of <br />gate coefficient (CGCG) vs. time (TCG) described on <br />cards (58) and (60). If KCG is negative, it <br />activates the floodplain compa~tments option and <br />represents total number of floodplain compartments <br />(maximum of 20 allowed). <br /> <br /> <br />KCG <br /> <br />Card (21) is omitted unless NTT >0, (card 20)). <br /> <br />NT(K) - 6 I 10 Format <br /> <br />NT(K) <br /> <br />Number of cross sections (1 through NS) at which <br />hydrograph plots are desired; K goes from 1 to NTT. <br /> <br />Cards (22 - 23) are omitted unless KSA<O, (carn (20)). <br /> <br />SMF, NTSM, NSMR - F10.2, 2 I 10 <br /> <br />SMF <br /> <br />Smoothing factor, 0.5 < SMF < 0,9, The larger SMF <br />values produces greater smoothing, <br />Parameter indicating type of smoothing. If NTSM=1, <br />smoothing of widths along x-axis; if NTSM=2, <br />smoothing of widths in vertical where maximum <br />width/ft change is IKSAI*50; if NTSM=3, smoothing <br />of elevations along x-axis; NTSM=4, type 1 and type <br />2 smoothing; if NTSM-5, type 1, 2, and 3 smoothing. <br />Number of separate smoothing reaches within the total <br />routing reach; maximum of 7 allowed. <br /> <br />NTSM <br /> <br />NSMR <br /> <br />'::: <br />
