SEDIMOT 11 DOES NOT CONSIDER-ERODIBLE CHANNELS SO BETA IS SET EQUAL TO .01. IF THE USER WISHES TO EVALUATE THE TRANS- PORT CAPACITY OF THE STREAM DIRECTLY HE/SHE SHOULD USE SUBROUTINE SL-OSS. *** HYDRAULIC INPUT VALUES FOR SUBWATERSHEDS *** WATER AREA CURVE TC TT ROUTING COEFFICIENTS UNIT SHED ACRES NUMBER HR HR K-HRS X HYDRO ------------------------------------------------------------------------ 1 52.00 71.00 0.380 0.000 0.000 0.00 1.0 2 12.00 71.00 0.290 0.050 0.050 0.39 1.0 *** SEDIMENT INPUT VALUES FOR SUBWATERSHEDS *** WATER SEG SOIL LENGTH SLOPE CP PART SURF SHED NUM K FEET PCT VALUE OPT COND ---------------------------------------------------------------------------- 1 1 0.25 400.0 8.75 1.000 1 .0 0.0 2 1 0.25 200.0 7.50 1.000 1 .0 0.0 * * * COMPUTED VALUES FOR INDIVIDUAL WATERSHEDS * * * WATERSHED PEAK FLOW RUNOFF SEDIMENT DIAM DELIVERY DELIVERY (CFS) ( INCHES) TONS (MM) RATIO 1 RATIO 2 ---------------------------------------------------------------------- 1 2.26 0.13 60.16 0.003 0.570 1.000 2 0.60 0.13 7.18 0.O04 0.619 1.000 NOTE: SEDIMENT DOES NOT INCLUDE POSSIBLE DEPOSITION BY DELIVERY RATIO 2 ***** SUMMARY TABLE FOR TOTAL WATERSHED ***** --------------------------------------------- RUNOFF VOLUME = 0.6719 ACRE-FT PEAK DISCHARGE = 2.7341 CFS AREA = 64.0000 ACRES TIME OF PEAK DISCHARGE = 12.30 I-IRS BETA = 0.0100 RAINFALL EROSITIVITY FACTOR = 13.39 El UNIT PEAK CONCENTRATION = 124508.31 MG/L PEAK SETTLEABLE CONCENTRATION = 28.93 ML/L PEAK SETTLEABLE CONCENTRATION = 40209.08 MG/L TOTAL SEDIMENT YIELD = 67.3441 IONS REPRESENTATIVE PARTICLE SIZE = 0.0042 MM TIME OF PEAK CONCENTRATION = 12.30 HRS
