F. ABSORPTION WIDTH Absorption ratio: � 2 � <br /> 1. Absorption width equals absorption ratio times rock layer width <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 rodc layer 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 restriding lay�(C1) <br /> 3.0 ft - 1.8 ft= 1.2 ft <br /> b.Mound height at the upslope edge of rock layer=depth of dean sand for separation(G2a) <br /> at upslope edge plus depth of rodc layer(1 foot)to depth of cover(1 foot) <br /> 1.2 ft+1ft+1 ft= 3.2 ft <br /> c.Upslope beRn multiplier based on I�d slope(see figure D-34J <br /> Selected be�m multiplier: 270 <br /> d.Upslope width=berm multiplier(G2c)times upslope mound height(G2b): <br /> 2.70 x 3.2 ft = 10.0 ft <br /> DOWNSLOPE <br /> e.Drop in elevation=rodc layer width(D2)times percent landslope(C5)I 100 <br /> 10.0 ft x 12.0 % /100= 1.2 ft <br /> f.Downslope rraund height=de�h of de�sand for slope difference(G2e) <br /> at downslope rock edge plus the mound height at the upslope edge of rock lay�(2b) <br /> 1.2 ft + 3.2 ft= 4.4 ft <br /> g.Drnmsbpe berm multiplier based on percent land slope(see Figure D-34 <br /> Seleded b�m multiplier: 4.95 <br /> h.Downslope width=dovmslope multiplier(62g)6mes downsbpe mound height(G2� <br /> 4.95 x 4.4 = 22.0 ft <br /> i.Select great��G1 and G2h as the downslope width 22.0 ft <br /> j.Total mound width is the sum of upslope(G2d)width plus rodc layer width(D2)plus downslope�(G2i) <br /> 10.0 ft+ 10.0 ft+ 72.0 ft= 42.0 ft <br /> k.Total mound length is the sum of upslope width(G2d)plus rodc layer length(D3)plus upslope width(G2d) <br /> 10.0 ft + 50.0 ft+ 10.0 ft= 70.0 ft <br /> Final Dimensions (slope>1% d2.0 ft x 70.0 ft <br /> I hereby certify th�all wak has been completed in accord�ce with all applicable ordinances,rules&laws. <br /> =� {signature) 810(ticense#) 6162008(datej <br /> Page 2 of 5 <br />
