� F. ABSORPTION WIDTH Absorption ratio: 2 <br /> 1. Absorp6on width equals absorption raHo times rodc layer width <br /> 2.00 x 10.0 ft = 20.0 ft <br /> G. MOUND SLOPE WIDTH�LENGTH(6reater 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. Calculate mound size <br /> UPSLOPE <br /> a.Depth o#dean sand at upslope edge of rock layer=3 feet minus distance to restricting layer(C1) <br /> 3.0 ft - 2.0 ft= 1.0 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 ft+1ft+1 ft= 3.0 ft <br /> a Upslope berm multiplier based on land slope(see figure D-34) <br /> Selected berm multiplier: 2.70 <br /> d.Upslope width=berm multiplier(G2c)Nmes upslope mound height(G2b): <br /> 2.70 x 3.0 ft = 9.0 ft <br /> DOWNSLOPE <br /> e.Drop in elevation=rodc layer width(D2)times percent landslope(C5)/100 <br /> 10.0 ft x 12.0 % 1100= 12 ft <br /> f.Downslope mound height=depth of Gean sand for slope difference(G2e) <br /> at downslope rock edge plus the mound height at the upslope edge of rock layer(2b) <br /> 1.2 ft + 3.0 ft= 4.2 ft <br /> g.Downslope berm multiplier based on percent land slope(see Figure D-34 <br /> Selected berm multiplier: <br /> h.Dovmslope width=dovmslope multipiier(G2g)times downslope mamd height(G2� <br /> 0.00 x 4.2 = 0.0 ft <br /> i.Select greater of�1 and G2h as the downslope width 10.0 ft <br /> j.Total mound width is the sum of upslope(G2d)width plus rock layer width(D2)plus downslope width(G2i) <br /> 9.0 ft+ 10.0 ft+ 10.0 ft= 29.0 ft <br /> k.Total mound length is the sum of upslope width(G2d)plus rock layer length(D3)plus upslope width(G2d) <br /> 9.0 ft + 29.0 ft+ 9.0 ft= 47.0 ft <br /> Final Dimensions (slope>1%) 29.0 ft x 47.0 ft <br /> I hereby cerGfy that all work has been completed in acoordance with all applicable ordinances,rules&laws. <br /> (signature) 810(license#) �(date) <br /> Page 2 of 5 <br />
