<br /> 1. If landslope is�6 �ntore,subtract rock layer width from
<br /> adsorption width to obtain minimum downslope dike toe
<br /> al. 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: Sepuration� l.S feet
