� G: DOWNSLOPE 1��WIDTH
<br /> 1. If landslope is�6 �atore,subtract rock layer width from
<br /> adsorption width to obtain minimum downslope dike toe
<br /> a�,� ft-�ft =.�.2_feet
<br /> 2. Calculate Minimum�mound size based on geometery:
<br /> a. Determine deptlt of clean sand fill at upslope edge of rock
<br /> layer: Sepuration � ,� feet
<br /> b. Multiply rock layer width by landslope "`'0°` C01•�
<br /> to determine drop in elevation; , f r e o t a o .a

<br /> d. Enter table with landslope and upslope dike ratio.
<br /> Select dike multiplier of 3 , �s
<br /> e. Multiply dike multiplier by upslope mound height
<br /> to find upslope dike width: 3.s x 3,yS =1�_ feet
<br /> f. Add depth of clean sand for slope difference (2b) at
<br /> downslope edge,to the mound height at the upslope edge
<br /> of rock layer (2c) to find the downslope height;
<br /> 3.S ft+�,_ft = 3,9 feet
<br /> g. Enter table with landslope and downslope dike ratio.
