F. ABSORPTION WIDTH Absorptlon ratio: 2 <br /> 1. Absorption width equals absorption ratio times rock layer width �g <br /> 2.00 x 10.0 ft = 20.0 ft <br /> G. MOUND SLOPE WIDTH�LENGTH(Greater than 1%) <br /> 1. Downslope abso�ption width=absorption width minus rocklayer width <br /> 20.0 feet - 10.0 feet= 10.0 ft <br /> 2. Calculate mound size <br /> UPSLOPE <br /> a.Depth of dean sand at upslope edge of rodc layer=3 feet minus distance to restricting layer(C1) <br /> 3.0 ft - 1.0 ft= 2.0 ft <br /> b.Mound heigM at the upslope edge of rock layer=depth of dean sand for separation(G2a) <br /> at upslope edge plus depth of rock layer(1 foot)to depth of cover(1 foot) <br /> 2 ft+1ft+1 ft= 4.0 ft <br /> c.Upslope berm multiplier based on land slope(see figure D-34) <br /> Selected berm multiplier: 2.83 <br /> d.Upslope width=berm multiplier(G2c)times upslope mound height(G2b): <br /> 2.83 x 4.0 ft = 11.4 ft <br /> DOWNSLOPE <br /> e.Drop in elevation=rodc layer width(D2)times percent landslope(C5)!100 <br /> 10.0 ft x 6.0 °k I 100= 0.6 fl <br /> f.Downslope mound height=depth of clean sand for slope difference(G2e) <br /> at downslope rock edge plus the mound height at the upslope edge of rock layer(2b) <br /> 0.6 ft + 4.0 ft= 4.6 ft <br /> g.Downslope berm mu�iplier based on percent land slope(see Figure D-34 <br /> Selected berm multiplier: 3.66 <br /> h.Downslope width=downslope multiplier(G2g)times downslope mound heighi(G2� <br /> 3.66 x 4.6 = 16.9 ft <br /> i.Select greater of G1 and G2h as the downslope width 16.9 ft <br /> j.Total mound width is ihe sum of upslope(G2d)width plus rock layer width(D2)plus downslope width(G2i) <br /> 11.4 ft+ 10.0 ft+ 16.9 ft= 38.3 ft <br /> k.Total mound length is the sum of upslope width(G2d)plus rodc layer length(D3)plus upslope width(G2d) <br /> 11.4 ft + 63.0 ft+ 11.4 ft= 85.8 ft <br /> Final Dimensions slope>1%) 38.3 ft x 85.8 ft <br /> I hereby certify that�I work has been completed in accordance with all applicable adinances,rules 8�laws. <br /> (signature) 81�(license#) 12/19/'1006(date) <br /> Page 2 of 5 <br />
