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 />'a \, 1 ft - )y ft = 1 '7_ 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 , o feet LL' % '1 ,, <br />b. Multiply rock layer width by landslope to determine drop <br />in elevation; Slope Difference S ►1 �-� 16...d <br />y x �_% -1-100 feet �>`a ��+•-- <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 />I . U ft + 1 ft + 1 ft = ? u feet <br />d. Enter table on page bottom with landslope and upslope <br />dike ratio. Select dike multiplier of =i.:= <br />e. Multiply dike multiplier by upslope mound height <br />to get upslope dike width: 7. �) x = l) feet <br />f. Add the depth of slope difference (2b) to the upslope <br />height to get the downslope height <br />+ = feet <br />Enter table on page bottom with landslope and <br />downslope dike ratio. <br />Select dike multiplier of <br />Multiply dike multiplier by downslope mound height <br />to get downslope dike width: x = feet <br />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 />17 feet <br />Total mound width is the sum of upslope dike <br />width plus rock layer width plus downslope <br />dike width; <br />12 ft + )L ft + (; ft = �Lfeet upa. <br />Total mound length is the sum of upslope <br />dike width plus rock layer length plus <br />upslope dike width; <br />II f t + _r, 7_ft+I_ft= (feet <br />�.c T_A £ILtt,- <br />1r-----1 au unsv+ _Zl,p <br />3.1 <br />4.1 <br />Downslope <br />SA <br />61 <br />71 <br />31 <br />6.1 <br />1 <br />41 <br />7-1 <br />bl <br />% Jopr <br />0 <br />30 <br />♦0 <br />s0 <br />60 <br />70 <br />30 <br />40 <br />5.0 <br />60 <br />70 <br />s0 <br />1 <br />300 <br />6.17 <br />526 <br />63A <br />7i3 <br />291 <br />3V <br />676 <br />5" <br />6S4 <br />741 <br />2 <br />3 19 <br />6.1.s <br />536 <br />692 <br />6 16 <br />2 s1 <br />170 <br />4 SI <br />S 36 <br />414 <br />690 <br />330 <br />341 <br />- L" 1 <br />, jib <br />531/ <br />6 2S <br />7.32 <br />7" <br />b 16 <br />i 72 <br />2 15 <br />266 <br />_ <br />• 157 <br />3 lS <br />435 <br />6 17 <br />Sol <br />4114 <br />S.N <br />S FA6 <br />6 6S <br />06 <br />S <br />3S3 <br />Sim <br />667 <br />657 <br />1077 <br />21.1 <br />3.11 <br />600 <br />�Q <br />SI• <br />S71 <br />6 <br />366 <br />S26 <br />716 <br />v36 <br />12117 <br />24 <br />123 <br />as s <br />: U <br />IU <br />341 <br />7 <br />3 AO <br />536 <br />760 <br />1 U36 <br />1373 <br />2 u <br />3 12 <br />1 70 <br />23 <br />470 <br />S 13 <br />A <br />34VS <br />S Y <br />133 <br />1134 <br />1; 91 <br />2.42 <br />3 03 <br />157 <br />4 US <br />440 <br />i y <br />1 <br />11 <br />62S <br />901 <br />1306 <br />1A92 <br />236 <br />1% <br />343 <br />3P0 <br />430 <br />663 <br />10 <br />619 <br />667 <br />IOD <br />I500 <br />2333 <br />231 <br />106 <br />333 <br />371 <br />C12 <br />6.M <br />11 <br />{Y <br />7.16 <br />1111 <br />1715 <br />3041 <br />2.26 <br />275 <br />323 <br />361 <br />395 <br />426 <br />12 <br />♦ 661 <br />7 N <br />1230 <br />21 4! <br />43 %5 <br />2 21 <br />170 <br />3 12 <br />3 49 <br />3 10 <br />401 <br />i <br />1l <br />
