G. DOWNSLOPED WIDTH <br /> 1. If landslope is-3 ��more,subtract rock layer width from <br /> adsorption width to obtain minimum downslope dike toe <br /> ft- 1n ft=�2_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 ).0 feet <br /> b. Multiply rock layer width by landslope r too(Cover. <br /> to determine drop in elevation; t teat Re ad <br /> Slope Difference <br /> separation `'fi►et <br /> 1 x %i 100 = Ups <br /> feet slope oltference - et <br /> lope Width <br /> c. Add depth of clean sand for separation(2a) -�feet Rock Bed width <br /> at upslope edge,depth of rock layer(1 foot) to depth of 10 feet Downslope width <br /> cover(1 foot) to find the mound height at the upslope edge 1tet <br /> of rock layer, <br /> ft+ ift+ ift= 3.0 feet <br /> d. Enter table with landslope and upslope dike ratio. <br /> Select dike multiplier of y.0 <br /> e. Multiply dike multiplier by upslope mound height <br /> to find upslope dike width: 3-2 x L4.p =_.<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(20 to find the downslope height; <br /> €T=-_ feet <br /> g. Enter table with landslope and downslope dike ratio. <br /> Select dike multiplier of <br /> h. Multiply dike multiplier by downslope mound height <br /> to get downslope dike width: x feet <br /> L Compare the values of step G.1 and Step G.2h Select the <br /> greater of the two values as the downslope dike width; C7 <br /> eat <br /> ssso� otn> <br /> p <br /> ?,::: -� eat <br /> mound width is the sum of •<:�<:a:::::::;:;�::::::>:::;; <br /> Total ��� <br /> upslope dike (G-2e)width plus rock Racy Oed Width <br /> r <br /> teat <br /> el0e <br /> layer width(D.2)plus o uv: U <br /> o��aa"v�atn o � Width <br /> 1.tt_feet I test <br /> downslope dike widthG.2i - '.,:.:<:,;;:>•>• >:<:<:.;..:.,.:.::....::::::::;.:::: <br /> a4 <br /> 0 <br /> + � fee <br /> + f o t <br /> ft t <br /> ft u S <br /> S 1 <br /> # <br /> "wnsi'��� 'D 0 W <br /> efain <br /> :r <br /> . .:........ <br /> k.
