DOWNSLOPE DUM WIDTH <br /> 1. If landslope is 3% or more,subtract rock layer width from <br /> adsorption width to obtain minimum djpwnslope dike toe <br /> ft-/0 ft= / feet <br /> 2 Calculate Minimum mound size based on geometery: <br /> a. Determine depth of dean sand fill at upslope edge of rock <br /> layer:Separation feet <br /> b. Multiply rock layer width by landslope 1 toot cover <br /> to determine drop in elevation; <br /> I root Ro se <br /> Slope Difference Separation test <br /> 1Q x %+100= feet Slope Difference t <br /> Upslope Width <br /> c. Add depth of clean sand for separation(2a) test Roek esa 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 layerr� <br /> 1ft+ lft+ lft= feet <br /> d. Enter table with landslope and upslope dike ratio. <br /> Select dike multiplier of 4. <br /> e. Multiply dike multiplier by upslope mound height <br /> to find upslope dike width:3,7 x 4,n = /-s' 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 /> ft+ ft= feet <br /> g. Enter table with landslope and downslope dike ratio. <br /> Select dike multiplier of <br /> h. Multiply dike multiplier by downslope mound height <br /> to get downslope dike width: x = feet <br /> L 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 /> feet <br /> uoelooe wmtn <br /> j.
