G. DOWNSLOPE DIKE WII TI I <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 />ft = 1 '7_ feet <br />2. <br />Calculate minimum mound size based on geometery: <br />a. Determine depth of clean sand fill at upslope edge of rock <br />layer. Separation -<<t; feet <br />b. Multiply rock layer width by landslope to determine drop <br />in elevation; Slope Difference <br />I? x X%+100= -L/ feet <br />c.
