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 /> a�.� ft- In 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 /. U feet <br /> b. Muldply rock layer width by landslope to determine drop ,�„� <br /> in elevation; Slope Difference ';;,a,,,� <br /> 1 c� x s� % 1100 = • S� feet ��.-� <br /> c.
