�: IX}WNSLOPE 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 /> �L''1 ft-�ft=�'�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 l.c� feet <br /> b.

Enter table on page bottom with landslope and upslope <br /> dike ratio. Select dike multiplier of 'z>.'�� <br /> e. Multiply dike multiplier by upslope mound height <br /> to get upslope dike width: 3.D x 3•a� =1�feet <br /> f. Add the depth of slope difference(2b) to the upslope <br /> height to get the downslope height <br /> 3• D + �= 3,c� feet <br /> g.
