G. DOWNSLOPE DIKE WIDTH <br />1. If landslope is 3% or more, subtract rock layer width from <br />adsorp, ar.'width to obtain minimum downslope dike toe for <br />abso: ptto:t: <br />-2L-,-) ft- /eft=L_feet <br />2. Calculate mir►'mum mound size based on geometery: <br />a. Determine depth of clean sand fill at upslope edge of rock <br />layer: Separation 1, C, feet <br />b. Multiply rock layer width by landslope to determine drop I C- <br />in elevation; Slope Difference <br />/I--_ x " % + 100 S_ f2 et �-•- <br />c. Add depth of clean sand depth of clean ;:and for i-1 am <br />separation at +ipslope 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 />y. a ft + 1 ft + 1 ft = Z r O feet <br />d. Enter table on page bottom w..ith landslope and upslope <br />dike ratio. Select dike multiplier of <br />e. Multiply dike multiplier by upslope mound height <br />to get upslope dike widt:-i: x-- feet <br />f. Add the depth of slope difference (2b) to the upslope <br />height to get the downslope height <br />+ C c: feet <br />g. Enter table on page bottom with landslope and <br />downslope dike ratio. <br />Select dike Iultiplier of <br />h. Multiply dike multiplier by downslor <br />to get downslope dike width: . c- _ feet <br />i. Comt are the values of step G.l and 5' 1.
