F. ABSORPTION WIDTH Absorption ratio: 2 <br /> ' 1. Absorption width equals absorption ratio times rock layer width Site B <br /> 2.00 x 10.0 ft = 20.0 ft <br /> G. MOUND SLOPE WIDTH 8�LENGTH(Greater than 1°k) <br /> 1. Downslope absorption width=absorption width minus rock layer width <br /> 20.0 feet - 10.0 feet= 10.0 ft <br /> 2. Caiculate mound size <br /> UPSLOPE <br /> a.Depth of clean sand at upslope edge of rock layer=3 feet minus distance to restricting layer(C1} <br /> 3.0 ft - 1.3 ft= 1.7 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 /> 1.7 ft+1ft+1 ft= 3.7 ft <br /> c.Upslope berm multipiier based on land slope(see figure D-34) <br /> Selected berm multiplier. 2.94 I <br /> d.Upslope width=berm multiplier(G2c)times upslope mound height(G2b): <br /> 2.94 x 3.7 ft = 10.9 ft <br /> DOWNSLOPE <br /> e.Drop in elevafion=rock layer width(D2)times percent landslope(C5)!100 <br /> 10.0 ft x 9.0 96 /100= 0.9 ft <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 /> 0.9 ft + 3.7 ft= 4.6 ft <br /> g.Downslope bertn multiplier based on percent land slope(see Figure D-34 <br /> Selected berm multiplier: 5.18 <br /> h.Downslope width=downslope multiplier(G2g)times downslope mound height(G2� <br /> 5.18 x 4.6 = 23.9 ft <br /> i.Select greater of G1 and G2h as the dawnsbpe width 23.9 ft <br /> j.Total mound width is the sum of upslope(G2d)width plus rock layer width(D2)plus downslope width(G2i) <br /> 10.9 ft+ 10.0 ft+ 23.9 ft= 4d.8 ft <br /> k.Total mound length is the sum of upslope width(G2d)plus rodc layer length(D3)plus upslope width(G2d) <br /> 10.9 ft + 63.0 ft+ 10.9 ft= 84.8 ft <br /> Final Dime�sions (slope>1%) 44.8 ft x 84.8 ft <br /> I hereby certify that alt work has been completed in accordance with all applicable ordinances,rules&laws. <br /> (signature) 810(�icense#) 12/19/'ZW6 (date) <br /> Page 2 of 5 <br />
