'G. DOWNSLOPE DIKE WIPTl 1 <br />I. if landslope is 2.9 percent or less, Basal width includes both the <br />upslope and downslope dike widths, <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 _ . %- feet <br />b. Multiply rock layer width by landslope to determine drop lye <br />in elevation; Slope Difference <br />x `% + 100 = feet <br />c. Add depth of clean sand depth of clean sand for au M ,� w,— <br />separation at upslope edge (2a) to depth of rock layer to .,....� <br />rock depth and the depth of cover to find the total mound <br />height at upslope edge of rock layer; <br />ft + 1 ft + 1 ft = 4. c. feet <br />d. Enter table on page bottom with landslope and upslope <br />dike ratio. Select dike multiplier of <br />e. Mult;ply dike multiplier by upslope mound height <br />to get upslope dike width: -: -, x = /_5' feet <br />f. Add the depth of slope difference (2b) to the upslope <br />height to get the downslope height 4 L) + e = 4 . z feet <br />g. Enter table on page E-18 with landslope and downslope <br />dike ratio. Select dike multiplier of 4 ,., , <br />h. Multiply dike multiplier by downslope mound height <br />to get downslope dike width: - x - _ __L�1_ feet <br />i. Mininmum mound width is the sum of upslopl? dike <br />width plus rock layer width plus downslope dike wildth; <br />It L ft + ft + ft = feet <br />j. Subtract the Minimum width G.i from the Absorption <br />width FA to find the Additional Downslope required for <br />Absorption <br />ft- - ft = feet UPic <br />k. Add the Additional Downslope required for Absorptio: <br />to the downslope dike width and recalulate the Total <br />Mound Width which is is the suns of upslope dike <br />width plus rock layer width plus downslope dike width <br />' ft + ft + ft = - feet <br />1. Total mound length is the sum of upslope dike width <br />plus rock layer length plus upslope dike width; <br />ft + ft + ft = feet <br />----Tohllen6lfi `� _ <br />r' I <br />31 <br />41 <br />awns 7j <br />51 <br />61 <br />71 <br />31 <br />41 <br />— <br />ps opc <br />SI <br />6.1 <br />7.1 <br />91 <br />• w,p, <br />0 <br />31) <br />40 <br />50 <br />60 <br />7u <br />311 <br />{o <br />So <br />60 <br />7-0 <br />90 <br />1 <br />319 <br />{17 <br />526 <br />63tl <br />7%3 <br />741 <br />36*1 <br />476 <br />S66 <br />65{ <br />741 <br />2 <br />3 19 <br />{ 1� <br />5 5n <br />6 tl7 <br />6 14 <br />1 V <br />3 70 <br />{.54 <br />S-36 <br />614 <br />6910 <br />3 <br />3 JO <br />{S6 <br />S 66 <br />7 32 <br />6 66 <br />27, <br />357 <br />{.15 <br />$01 <br />S.74 <br />6.65 <br />{ <br />341 <br />{76 <br />62S <br />71ry <br />972 <br />2M <br />365 <br />417 <br />{M <br />S66 <br />606 <br />5 <br />353 <br />Sao <br />667 <br />6 57 <br />10 77 <br />2 61 <br />7 13 <br />4 00 <br />{ 62 <br />5.19 <br />S 71 <br />6 <br />366 <br />526 <br />714 <br />938 <br />1207 <br />2S{ <br />323 <br />3A5 <br />461 <br />403 <br />SAI <br />7 <br />310 <br />$36 <br />7 69 <br />103{ <br />13 73 <br />248 <br />3 12 <br />370 <br />{.23 <br />4.70 <br />S 13 <br />{ <br />395 <br />SU <br />111 <br />1156 <br />1591 <br />2Q <br />303 <br />3.57 <br />{0; <br />{{9 <br />y <br />9 <br />{ 11 <br />625 <br />It <br />I10{ <br />itl 92 <br />216 <br />2 W <br />345 <br />3.so <br />{.30 <br />:1 <br />10 <br />{29 <br />667 <br />11(0 <br />I500 <br />23393 <br />231 <br />2M <br />3.33 <br />3.7s <br />{.12 <br />{M <br />7.14 <br />11 11 <br />1765 <br />3043 <br />2 26 <br />2 76 <br />3.23 <br />3.61 <br />3 9S <br />{ 26 <br />12 <br />{b9 <br />7.69 <br />1250 <br />2143 <br />4175 <br />221 <br />270 <br />312 <br />3.0 <br />3S0 <br />{.0s <br />
