If landslope is 3% or more, subtract rock layer width from <br />adsorption width to obtain minimum downslope dike toe for <br />absorption: <br />U, > ft- ii✓, ft = If 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 i, c.,� feet <br />b. Multiply rock layer width by landslope to determine drop <br />in elevation; Slope Difference <br />_ x _% + 100 = feet <br />c. Add depth of clean sand depth of clean sand for =fi " = 4.
