G. DOWNSLOPE DIKE WIDTH <br />L If landslope is 3% or more, subtract rock layer width from <br />adsorption width to obtain minin- um downslope dike toe for <br />absorption: <br />:.7 ft -1Q ft = 1 yJ feet <br />2. <br />Calculate minimum mound size based on geometery: <br />a. Determine depth of clean sand fill at upslope edge of rock <br />layer: Separation J. v feet <br />b. Multiply rock layer width by landslope to determine drop <br />in elevation; Slope Difference <br />x : % + 100 = . _� feet <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 />_,(:' ft + 1 ft + 1 ft = -_ feet <br />d. Enter table on page bottom with landslope and upslope <br />dike ratio. Select dike multiplier of ,r; .3-1 <br />e. Multiply dike multiplier by upslope mound height <br />to get upslope dike width: 3.y x _ _ofeet <br />f. Add the depth of slope difference (2b) to the upslope <br />height to get the downslope height <br />3. n + . S = 3.S feet <br />g. Enter table on page bottom with landslope and <br />downslope dike ratio. <br />Select dike multiplier of S.D <br />h. Multiply dike multiplier by downslope mound height <br />to get downslope dike width: ,75 s- x -5- _ )j feet <br />i. Compare the values of step G.1 and Step G.2.h. Select the <br />greater f 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 />-I-L. ft + Z_ ft + ) ci ft = / feet up-w <br />k. Total mound length is the sum of upslope <br />dike width plus rock layer length plus <br />upslope dike width; <br />ft+ ft+ "eft= 1L��. feet <br />I bu c- <br />Do <br />V� <br />Tad Is"Sth <br />1 1 cl <br />kl It <br />W71/ 0p! <br />5:1 <br />fill <br />7-1 <br />31 <br />4.1 <br />5:1 0� <br />fill <br />71 <br />/:1 <br />% dop <br />0 <br />310 6.0 <br />5.0 <br />60 <br />7.0 <br />30 <br />6.0 <br />5.0 <br />60 <br />7.0 <br />/A <br />1 <br />30 6.17 <br />5.2L <br />63/ <br />7 S) <br />2 91 <br />3.ai <br />6.76 <br />5." <br />6_ <br />7 41 <br />2 <br />3.19 6J5 <br />5.56 <br />6/2 <br />/ 14 <br />2..33 <br />3.70 <br />54 <br />5.36 <br />6.14 <br />6.90 <br />3 <br />330 656 <br />5.// <br />7.32 <br />/.66 <br />2IS <br />3-37 <br />6.15 <br />S.0/ <br />5.79 <br />6.65 <br />6 <br />3.61 C76 <br />US7.0 <br />9.72 <br />2.66 <br />3.65 <br />6.17 <br />4 , <br />5.65 <br />606 <br />S <br />6 <br />3S/ S.0)f; <br />3,1 '� 5.26 <br />6" <br />/.57 <br />10 77 <br />261 <br />`T W) <br />6.00 <br />1 62 <br />5 19 <br />5.71 <br />7 <br />7.16 <br />9)S <br />12 07 <br />2 ;j <br />3.23 <br />3 9S <br />4 11 <br />493 <br />S 41 <br />33Q SS6 <br />7.69 <br />1ON <br />1373 <br />2 A <br />3 12 <br />3.70 <br />6 23 <br />470 <br />S 13 <br />/ <br />3.16 S.// <br />&33 <br />1 I S6 <br />1591 <br />. 42 <br />3.03 <br />3S7 <br />6 0S <br />6 49 <br />6.// <br />9 <br />6.11 l8 <br />9.09 <br />13A6 <br />19.92 <br />2.36 <br />LOG <br />3.65 <br />3.90 <br />6.30 <br />6.6s <br />10 <br />fib 6.67 <br />lob <br />15100 <br />2333 <br />231 <br />2.K <br />3-33 <br />3.75 <br />6.12 <br />6.M <br />11 <br />6.0 7.16 <br />11.11 <br />17.65 <br />3043 <br />226 <br />17/ <br />3.23 <br />3.61 <br />3.95 <br />626 <br />12 <br />6.M 7.69 <br />1230 <br />2143 <br />4375 <br />2 21 <br />270 <br />3 12 <br />149 <br />300 <br />6 (0 <br />
