.G. DOWNSLOPE I��WIDTH �
<br /> 1. If landslope is3�o ��ore,subtract rock layer width from
<br /> adsorption width to obtain minimum downslope dike toe
<br /> at�.� ft-�_ft=�Zfeet
<br /> 2. Calculate Minimum�mound sizg based on geometery:
<br /> a. Determine depth of clean sand fill at upslope edge of rock
<br /> layer: Separafion Lj�feet
<br /> b. Multiply rock layer_width by landslope `� ron�:co�.�
<br /> to determine drop in elevation; : reo� Ro ea

<br /> c. Add depth of clean sand for separation (2a) -�1e�t Ro�k e�a w�ecn
<br /> at upslope edge,depth of rock layer(1 foot) to depth of �reee DownstoDe WtGtn
<br /> cover (1 foot) to find the mound height at the upslope edge a� feet
<br /> of rock layer;
<br /> L�ft + lft+ lft= 3.s� feet
<br /> d. Enter table with landslope and upslope dike ratio.
<br /> Select dike multiplier of 3 � S� s Qu-�,a � 3•�s �-�-�-� ��
<br /> e. Multiply dike multiplier by upslope mound height ,
<br /> to find upslope dike width: 3•S� x�.S = �3 feet L3•�s � 3.s=�y ) a S� �`�
<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•� ft+ . 3 ft= 3, �feet
<br /> g. Enter table with landslope and downslope dike ratio.
<br /> Select dike multiplier of `i•S y
<br /> h. Multiply dike multiplier by downslope mound height
<br /> to get downslope dike width: y•S�-i x 3. � _ �� feet ,
<br /> i. Compare the values of step G.1 and Step G.2h Select the
<br /> greater of the two values as the downslope dike width; ��
