F. ABSORPTION WIDTH <br /> 1. Absorption width equals absorption ratio(see Figure D-33)times rock layer width <br /> 2 1 x 10.0 ft = 20.0 ft <br /> G. MOUND SLOPE WIDTH&LENGTH(Greater than 1%) <br /> 1. Downslope absorption width=absorption width minus rock layer width <br /> 20 feet - 10 feet= 10 feet <br /> 2. Calculate mound size <br /> UPSLOPE <br /> a.Determine depth of clean sand at upslope edge of rock layer=3 feet minus distance to restricting layer(C1) <br /> 3 ft - 1.83 ft= 1.17 feet <br /> b.Mound height at the upslope edge of rock layer=depth of clean sand for separation(G2a) <br /> at upslope edge plus depth of rock layer(1 foot)to depth of cover(1 foot) <br /> 1.17 ft+1ft+1 ft= 3.17 feet <br /> c.Upslope berm multiplier based on land sloe see figure D-34) <br /> Select berm multiplier of 1 3.23 <br /> d.Upslope width=berm multiplier(G2c)times upslope mound height(G2b): <br /> 3.23 x 3.5 ft = 11.3 feet <br /> D:14 SI.C)PI's MElr.:l'FPr.11{ii'1'Ar3rJz <br /> i [and _v... 1JP51(JI'E EJpWN5E.{)PF: <br /> 41u#re nlul@erliln hx a:Minua mnitipplirts Gm vatlriaua <br /> in' altrpe ratios ciapa ratios <br /> �!_.._.�azo..,......�!..��...uai_......�:1. g�4.�_ �..,.;�1�......�.�,.�,.....��E..�.._.�:i....�.,.�:e__ <br /> g 0 3.0 4A 5.0 6A 7.0 6.0 3.0 4.0 5.0 6A 7.0 <br /> 1 2.41 3.85 4.76 5.66 6.34 7.41 3.04 4.17 5.26 6.38 7.53 <br /> s <br /> 2 2.83 3.70 4.3.1 5-36 b.111 6.40 3.19 413 5.36 6.82 6.1.1 <br /> 3 L-13 3.57 4-13 5.08 S.74 tills 3..30 4.31 SAO 7.32 6.06 <br /> 4 2.68 3.15 4.E' 4A1 5:10 600 3.41 4.70 6.25 7A4 9.72 <br /> 4 <br /> 5 2.61 3_13 4.00 4.02 5,I4 5.79 3.53 SAO 6.67 6.57 10.7-1! <br /> 6 2154 3.23 3.83 4.-1 E .1.43 5.41 3.66 5.26 7.14 9..18 12.07 <br /> L48 3.12 3.70 4.23 C-10 5.13 3.80 5.30 7A9 10.31 13:73 <br /> 6 L•12 3.03 3.37 US 4<l4 4A8 3.95 5.88 633 11.54 15.91 <br /> 9 230 2.91 3:13 3.90 410 4AS 4.11 6.23 9.04 13.0.1 HIM <br /> l0 2.31 2.80 3_33 3.73 4.12 4.4.1 4.29 6.07 10A0 15.00 2333 <br /> 11 2.24 1.76 1.22 1.41 VIS 4.261 4.46 7.1'1 1.1.11 17AS 111.43 <br /> 12 .... 2»11 T 2._.0..-._3.12 <br /> 1.49 <br /> 9 .
