G. DOWNSLOPE DIKE WIDTH <br />1: If landslope is 3% or more, subtract rock layer width from <br />adsorption width to obtain minimum downslope dike toe for <br />absorption: <br />U,kft- Lv ft = _L_L 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 1, 0 feet <br />b. Multiply rock layer width by landslope to determine drop <br />in elevation; Slope Difference �.... <br />-LL x % i 100 = -- feetIL <br />�+--�- <br />c. Add depth of clean sand depth of clean sand for I _ � a.-.. <br />separation at upslope edge (2a) to depth of rock layer to -6.

Enter table on page bottom with landslope and upslope <br />dike ratio. Select dike multiplier of -.� s•Y„,�., <br />e. Multiply dike multiplier by upslope mound height <br />to get upslope dike width: x = feet <br />f.

Enter table on page bottom with landslope and <br />downslope dike ratio. <br />Select dike multiplier of S J D to <br />h. Multiply dike multiplier by downslope mound height <br />to get downslope dike width: 3.o x 9.a4 = L feet <br />i. Compare the values of step G.1 and Step G.2.h.
