F. ABSORPTION WIDTH Absorption ratio: 2 <br /> 1. Absorption width equals absorption ratio times rock layer width Ske A <br /> 2.00 x 10.0 ft = 20.0 ft <br /> G. MOUND SLOPE WIDTH 8 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 /> 2. Ca�ulate mound size <br /> UPSLOPE <br /> a.Depth of clean sand at upslope edge of rodc layer=3 feet minus distance to restricting layer(C1) <br /> 3.0 ft - 1.6 ft= 1.4 ft <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 /> 1.4 ft+1ft+1 ft= 3.4 ft <br /> c.Upslope berm multipiier based on land slope(see figure D-34) <br /> Selected berm multiplier: 3.03 <br /> d.Upslope width=berm mulGplier(G2c)6mes upslope ma�nd height(G2b): <br /> 3.03 x 3.4 ft = 10.4 ft <br /> DOWNSLOPE <br /> e.Drop in elevation=rock layer width(D2)times percent landslope(C5)/100 <br /> 10.0 ft x 8.0 % /1�= 0.8 ft <br /> f.Downslope mound height=depth of dean sand for slope difference(G2e) <br /> at downslope rock edge plus the mound height at the upslope edge of rock layer(2b) <br /> 0.8 ft + 3.4 ft= 4.2 ft <br /> g.Downslope benn muitiplier based on percent land siope(see Figure D-34 <br /> Selected berm mulGplier. 5.88 <br /> h.Downslope width=downslope mui6plier(G2g)times downslope mound height(G2� <br /> 5.88 x 4.2 = 24.7 ft <br /> i.Select greater of G1 and G2h as the downslope width 24.7 ft <br /> j.Total mound width is the sum of upslope(G2d)width plus rock layer width(D2)plus downslope width(G2i) <br /> 10.4 ft+ 10.0 ft+ 24.7 ft= 45.1 ft <br /> k.Totat mound length is the sum of upslope width(G2d)plus rodc layer length(D3)plus upslope width(G2d) <br /> 10.4 ft + 63.0 ft+ 10.4 ft= 83.8 ft <br /> Final Dimensions (slope>1%) 45.1 ft x 83,8 ft <br /> I hereb certify that al►work has been completed in accordance with all applicable ordinances,rules&laws. <br /> (signature) 810(license#) 12I19/2006(date) <br /> Page 2 of 5 <br />
