If iandslope is 3% or more, subtract rock layer width from <br />adsorption width to obtain minimum downslope dike toe for <br />absorption: <br />ft - )_ ft = I feet <br />2. Calculate minimum mound size based on geometery: <br />a. Determine depth of clean sand fill at upslope edge of rock <br />layer: Separation 1 • feet <br />b. Multiply rock layer width by landslope to determine drop <br />in elevation; Slope Difference <br />x Li %+100=, Ll feet I=�. <br />l:,vy.Wd► <br />c. Add depth of clean sand depth of clean sand for <br />separation at upslope edge (2a) to depth of rock layer to <br />rock depth and the depth of cover to find the total mound <br />height at upslope edge of rock layer; <br />/.1 ft + 1 ft + 1 ft = 3.3 feet <br />d. Enter table on page bottom with landslope and upslope <br />dike ratio. Select dike multiplier of 3, L) t. <br />e. Multiply dike multiplier by upslope mound height <br />to get upslope dike width: ,.-, x ' = )_feet <br />f. Add the depth of slope difference (2b) to the upslope <br />height to get the downslope height <br />�.3 + , LL_= 3.1 feet <br />g. Enter table on page bottom with landslope and <br />downslope dike ratio. <br />Select dike multiplier of 1-1.^ <br />h. Multiply dike multiplier by downslope mound height <br />to get downslope dike width: x a = _I ,�' feet <br />i. Compare the values of step G.l and Step G.2.h. Select the <br />greater of the two values as the downslope dike width; <br />feet <br />j. Total mound width is the sum of upslope dike <br />width plus rock layer width plus downslope <br />dike width, <br />-LL_ ft + 10 ft + _I tf ft feet upa. <br />k. Total mound length is the sum of upslope <br />dike width plus rock layer length plus <br />upslope dike width; <br />_ I ft + a ft + __!__I_ ft = feet <br />1 V a1 1Ldl <br />!1 <br />l•1 <br />wn. ope <br />S:1 <br />f�l <br />7:1 <br />3:1 <br />1:1 <br />'Tel <br />fOpe <br />SKI <br />kI <br />7:1 <br />3:1 <br />It dsA <br />0 <br />3a <br />t0 <br />5.0 <br />610 <br />7.0 <br />10 <br />t0 <br />&0 <br />to <br />7.0 <br />to <br />1 <br />2 <br />3o <br />U7 <br />Si <br />U3 <br />7S3 <br />Lp <br />3.15 <br />UI <br />S.66 <br />t51 <br />7. 1 <br />3 <br />Ut <br />435 <br />531 <br />t32 <br />t11 <br />In <br />170 <br />151 <br />535 <br />t11 <br />t10 <br />4 <br />3a <br />S# <br />732 <br />1111 <br />L75 <br />t35 <br />SAS <br />S.79 <br />t6 <br />3A1 <br />t34 <br />7M <br />f.72 <br />LW <br />t17 <br />tN <br />54, <br />1.01 <br />6 <br />3fi <br />516 <br />7.14 <br />&57 <br />1.3e <br />I L07 <br />254 <br />3.D <br />400 <br />3.6 <br />1.62 <br />1.11 <br />111 <br />1.13 <br />S71 <br />5.41 <br />7 <br />3 <br />3:D <br />M <br />7.60 <br />1034 <br />1373 <br />144 <br />3.11 <br />3.70 <br />tD <br />4.70 <br />S.13 <br />33S <br />LM <br />W <br />1154 <br />I5.11 <br />L42 <br />103 <br />W <br />US <br />to <br />I.L <br />11 <br />411 <br />&V <br />t2S <br />t0 <br />9JX <br />ICA <br />13.0/ <br />ISAO <br />1.12 <br />2J33 <br />L36 <br />L31 <br />LM <br />is <br />143 <br />311 <br />110 <br />175 <br />l30 <br />U2 <br />1 /6 <br />Il <br />12 <br />t10 <br />7.14 <br />11.11 <br />176S <br />30.41 <br />126 <br />179 <br />ID <br />161 <br />115 <br />4A <br />111 <br />US <br />7.0 <br />1230 <br />21.43 <br />43.75 <br />121 <br />170 <br />111 <br />3.0 <br />3.0 <br />4.0/ <br />
