<br /> <br />• <br />SEDIMENT VOLUME -Pond #2 <br />Uu the universal wil lose equation. <br />The Topographic Factor LS u d~cult to evaluate for a steep mountainous dni~uge area. Accordin g to the <br />LS factor hble, when the lrngth of slope exceeds 400 feet and a percent elope ezcxde 24 pecent, <br />wit loss eRimala an speculative as these values au beyond the range of mea~ch data. Theufo~e, <br />an LS futor using 400 feet and 24 penxnt will be used for tltie calculation. <br />SEDIMENT VOLUME -Pond #2 <br />Glculate Weighted Avenge C-Factor <br />Ana Acres %Canopy %Cover C-Factor Extended <br />Disturbed 4.3 0.0 0.0 1.0000 4.300 <br />Rcvcgetated Area 1.9 0.0 30.0 0.1500 0.285 <br />Juniper Woodland 2.7 47.0 70.4 0.0628 0.170 <br />TOTAL 8.9 Wt Ave. 0.53 <br />SEDIMENT VOLUME -Pond #2 <br />A=RKLSCP <br />R = rainfiR fulor 30.00 <br />K = wit ewdibility factor 0.37 <br />LS =combined length elope faetor 400' - 24% 11.20 <br />C = cropping managemrnt factor 0.534 <br />P = eweion crntrol practice factor 0.73 <br />A=sediment, lona/acmJywr 49.81 <br />ONE YEAR SEDIMENT VOLUME -ACRE FEET 0.18 <br />8.90 ACRES - 115 #/CF <br />TOTAL REQUE2ED SEDIMENT POND CAPACffY - AF 0.51 <br />RUN-0FF VOLUME - -Pond #3. #4, and Waste Area <br /> Pnxip D'uect Runoff <br />Area Attq Curve # Amount Run-off Vol A-F <br />Diaunbed 20.7 88 1.7 0.73 1.26 <br />RevegWted Ames 9.0 81 1.1 0.42 0.32 <br />Juniper Woodland 16.2 61 L7 0.03 0.04 <br />TOTAL 45.9 1.61 <br />TOTAL REQUIRED WATER VOLUME - _ p-F 1.61 <br />3 <br />
