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 /> /S.Zft- �� ft = 5�• Zfeet <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 I feet <br /> b.
