F. ABSORPTION WIDTH Absorption ratio: 2 <br /> 1. Absaption width equ�s absorption ratio times rodc layer width Primarv Site <br /> 2.00 x 10.0 ft = 20.0 ft <br /> �. MOUND SLOPE WIDTH�LENGTH(Greaber than 1%) <br /> 1. Downslope absorption width=absorption width minus rodc layer width <br /> 20.0 fcet - 10.0 feet= 10.0 ft <br /> 2. Calculate mound size <br /> UPSLOPE <br /> a.Depth af dean sar�d at upslope edge of rodc layer=3 feet minus distance to res6iding layer(C1) <br /> 3.0 ft - 1.8 ft= 1.2 ft <br /> b.Mound height at the upslope edge of rodc layer=depth af dean sand for sep�ation(G2a) <br /> at upslope edge plus depth of rodc lay�(1 foof)to depth ofi caver(1 foot) <br /> 1.2 ft+1ft+1 ft= 3.2 ft <br /> c.ups�ope berrn mu�tiplier based on�and s�ope(see figure D-34) <br /> Selected berm multiplier: 2.86 <br /> d.Upslope width=berm multi'plier(G2c)6mes upslope mound height(G2b): <br /> 2.86 x 3.2 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 7.0 % /100= 0.7 ft <br /> f.Downslope mound height=depth of dean s�d for slope d'rfferer�e(G2e) <br /> at downslope rodc edge plus the mound height at the upslc�pe edge af rock layer(2b) <br /> 0.7 ft + 3.2 ft= 3.9 ft <br /> g.Downslope t�m multiplier based on percent land slope(see Figure a34 <br /> Seleded berm multiplier: 5.56 <br /> h.Downslope width=downslope mul6plier(G2g)bmes downslope mound height(G2� <br /> 5.56 x 3.9 = 21.0 ft <br /> i.Select great�of G1 and G2h as the downslope width 21.0 ft <br /> j.Total mound width is the sum of upslope(G2dj�plus rodc layer width(D2)plus downslope width(G2i) <br /> 9.0 ft+ 10.0 ft+ 21.0 ft= 40.0 ft <br /> k.Total mound length is the sum of upslope width(G2d)plus rodc layer length(D3)pfus ups�ope width(G2d) <br /> 9.0 ft + 75.0 ft+ 9.0 ft= 93.0 ft <br /> Final Dimensions (slope>1%) 40.0 ft x 93.0 ft <br /> I hereb work has been completed in accadance with all applicable ordin�ces,rules&laws. <br /> (signature) 810 (►icense#) 2I112008(date) <br /> Page 2 of 5 <br />
