G: DOWNSLOPE DIKE WIDTH <br />I. If 'landslope is 3% or more, subtract rock layer width from <br />adsorption width to obtain minimum downslope dike toe for <br />absorption: <br />ft - ft = 1 I? feet <br />Calculate minimum mound sire based on geometery: <br />a. Determine depth of clean sand fill at upslope edge of rock <br />layer. Sepamion /, v feet <br />b. Multiply rock layer width by landslope to determine drop <br />In elevation; Stop Di/jrerence 1.. <br />v x S- 96 + im <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 raver to find the total mound <br />height at upslope edge of rock layer; <br />• 0 ft + 1 ft + 1 ft = ? feet <br />d. Enter table on page bottom with landslope and upslope <br />dike ratio. Select dike multiplier of 3 . . <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 />S. LD + _ feet <br />g. Enter table on page bottom with landslope and <br />downslope dike ratio. <br />Select dike multiplier of 5. U <br />h. Multiply dike multiplier by downslope mound height <br />to get downslope dike width: x -. = 1 r' feet <br />I. Compare the values of step G.1 and Step G.2.h. Select the <br />greater of the two values as the downslope dike width; <br />1 �4 feet <br />k. <br />Total mound width is the sum of upslope dike <br />width plus rock layer width plus downslope <br />dike width; <br />l 0_ ft + ft + ? f ft = -2 4' feet L <br />Total mound length is the sum of upslope <br />dike width plus rock layer length plus <br />upslope dike width; <br />ft + r c ft + i ft = feet <br />h TOW LOW& <br />kt <br />t1 <br />1M111 <br />S1 <br />k1 <br />7:1 <br />11 <br />11 <br />7.00" <br />&I <br />!t <br />0A <br />0 <br />11 <br />a0 <br />1.0 <br />40 <br />70 <br />3.0 <br />l0 <br />f0 <br />as <br />7J <br />Y <br />1 <br />10N <br />417 <br />M <br />a70 <br />777 <br />t" <br />Ill <br />476 <br />111 <br />GA <br />1A <br />I <br />I.0 <br />1.11 <br />9A <br />a <br />114 <br />to <br />).70 <br />am <br />LU <br />414 <br />a01 <br />I <br />Is <br />a!1 <br />I.� <br />77? <br />all <br />171 <br />IN <br />a71 <br />1w <br />L1• <br />&At <br />/ <br />It <br />l71 <br />aJl <br />711 <br />9.77 <br />J11 <br />� <br />4.17 <br />1M <br />&0 <br />aw <br />1 <br />1A <br />' I01 <br />am <br />a37 <br />1077 <br />261 <br />C Ll/ <br />4 <br />/ a <br />&SO <br />SA/ <br />111 <br />&Z <br />7.14 <br />•!1 <br />1 J 07 <br />J i/ <br />I.1) <br />I r <br />/./t <br />to <br />$Al <br />7 <br />1w <br />1!0 <br />7M <br />tell/ <br />17.77 <br />2/1 <br />LIJ <br />7.10 <br />/.2 <br />4.10 <br />1.11 <br />1 <br />Lw <br />iw <br />w <br />us/ <br />17.•1 <br />to <br />I.01 <br />I.f/ <br />/.r <br />ar <br />40 <br />• <br />/.11 <br />LS <br />901 <br />110/ <br />1192 <br />2.16 <br />!M <br />IA1 <br />LM <br />as <br />/r <br />le <br />/20 <br />am <br />W <br />150 <br />13s1 <br />231 <br />is <br />7.71 <br />I.7! <br />u: <br />4&M <br />11 <br />U9 <br />1.14 <br />11.11 <br />1716 <br />MA1 <br />131 <br />2.70 <br />1.71 <br />IAI <br />to <br />US <br />13 <br />40 <br />7.M <br />It" <br />21A7 <br />an <br />tt1 <br />L70 <br />W <br />to <br />is <br />aw <br />
