F. ABSORPTION WIDTH Absorption ratio: 2 <br /> 1. Absorption width equals absorption ratio times rock layer width Futuro Sft(� <br /> 2.00 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 /> 20.0 feet - 10.0 feet= 10.0 ft <br /> l <br /> � 2. Calculate mound size 1 i <br /> UPSLOPE <br /> a.Depth of dean sand at upslope edge of rock layer=3 feet minus distance to restricting layer(C1) <br /> 3.0 ft - 1.4 ft= 1.6 ft <br /> b.Mound height at the upslope edge of rock layer=depth of dean sand for separation(G2a) <br /> at upelope edge plus depth of rock layer(1 foot)to depth of cover(1 foot) <br /> 1.6 ft+1ft+1 ft= 3.6 ft <br /> c.Upslope berm multiplier used on land slope(see figure D-34) <br /> Selected berm multiplier: 3.03 <br /> d.L"lope width=berm mulGplier(G2c)times upslope mound height(02b): <br /> 3.03 x 3.6 ft = 11.0 ft <br /> DOWNSLOPE <br /> e.Drop in elevation=rock layer width(D2)times percent landslope(C5)/100 <br /> 10.0 ft x 8.0 % /100= 0.8 ft <br /> f.Downslope mound height=depth of dean sand for slope difference(132e) <br /> at downslope rock edge plus the mound height at the upslope edge of rock layer(2b) <br /> 0.8 ft + 3.6 ft= 4.4 ft <br /> g.Downslope berm multiplier based on percent land slope(see Figure D-34 <br /> Selected berm multiplier: 3.95 <br /> h.Downslope width=downslope ffOAPlier(G29)times downslope mound 11e04G21) <br /> 3.95 x 4.4 = 17.4 ft <br /> i.SeW greater of G1 and 132h as the downslope width 20.0 ft <br /> j.Total mound width is the sum of upslope(G2d)width plus rock layer width(D2)plus downslope width(G2i) <br /> 11.0 ft+ 10.0 ft+ 20.0 ft= 41.0 it <br /> k.Total mound length is the sum of upslope width(G2d)pus rock layer length(D3)plus upslope width(G2d) <br /> 11.0 ft + 75.0 ft+ 11.0 ft= 97.0 ft <br /> Final Dimensions >1% 41.0 ft x 97.0 ft <br /> I hereby certify that all work has been completed in accordance with all applicable ordinances,rules&laws. <br /> (signature) 810(license#) 3/11/2007(date) <br /> Page 2 of 5 <br />
