DOWNSLOPE DIKE WIDTH <br /> 1. If landslope is 3%D or more,subtract rock layer width from <br /> adsorption width to obtain minimum downslope dike toe <br /> Zo ft- 10 ft=/0 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 J _feet <br /> b. Multiply rock layer width by landslope 1100 cover <br /> to determine drop in elevation; <br /> I lost Ro ed <br /> Slope Difference ' separation feet , <br /> ZV x Z %+ 100= feet Slope Difference.� t <br /> uvs ve Width <br /> c. Add depth of clean sand for separation (2a) - -feet Ra.d width <br /> at upslope edge,depth of rock layer(1 foot) to depth of feet Downslope width <br /> cover(1 foot)to find the-mound height at the upslope edge feet <br /> of rock layer; <br /> / ft+ lft+ lft= Y feet <br /> d. Enter table with landslope and upslope dike ratio. <br /> Select dike multiplier of Z# 7 0 <br /> e. Multiply dike multiplier by u slope mound height <br /> to find upslope dike width: x x.70=--a_ feet <br /> f. Add depth of clean sand for slope difference(2b) at <br /> downslope edge, to the mound height at the upslope edge <br /> of rock layer(20 to find the downslope height; <br /> _0 ft+1_ft= 41 feet <br /> g. Enter table with landslope and downslope dike ratio. <br /> Select dike multiplier of-7• G <br /> h. Multiply dike multiplier by dow slope mound height <br /> to get downslope dike width: �► x =- b feet <br /> i. Compare the values of step G.1 and Step G.2h Select the <br /> greater of the two values as the downslope dike width; <br /> -70 - feet <br /> UD De wletn <br /> j.
