G. ' DOWNSLOPE IPM WIDTH
<br /> 1. If landslope is-X% more,subtract rock layer width from
<br /> adsorption width to obtain minimum downslope dike toe
<br /> pi-1) ft- in ft =i_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 a.o feet
<br /> b. Multiply rock layer width by landslope t reit cover
