G. DOWNSLOPE DIKE WIDTH <br />L If landslope is 3% or more, subtract rock layer width from <br />adsorption width to obtain minimum downslope dike toe for <br />absorption: <br />/5.Z ft - /O ft = 5• Z 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 l feet <br />b. Multiply rock layer width by landslope to determine drop <br />in elevation; Slope Difference <br />/O x ;_% i 100 = 0, feet ems,--- <br />c. Add depth of clean sand depth of clean sand for <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 />I_ ft + 1 ft + 1 ft = ,3 feet <br />d. Enter table on page bottom with landslope and upslope <br />dike ratio. Select dike multiplier of 4 00 <br />e. Multiply dike multiplier by upslope mound height <br />to get upslope dike width: �. 00 x 3 = _Meet <br />f. Add the depth of slope difference (2b) to the upslope <br />height to get the downslope height <br />3+ 0,3 =_2feet <br />g. Enter table on page bottom with landslope and <br />downslope dike ratio. <br />Select dike multiplier of <br />h. Multiply dike multiplier by downslope mound height <br />to get downslope dike width: L,G 7 x 34 = _Z!C feet <br />i. Compare the values of step G.1 and Step G.2.h. Select the <br />greater of the two values as the downslope dike width; <br />ZS feet <br />j. Total mound width is the sum of upslope dike <br />width plus rock layer width plus downslope <br />dike width; <br />_2- ft + / ° ft +`ZS ft = Meet uF,m <br />k. Total mound length is the sum of upslope <br />dike width plus rock layer length plus <br />upslope dike width; <br />eft+ SO ft+ /Z ft= Meet <br />i,3Y7+.wZS7 <br />i,4Yl XID ' 'tB3 <br />rTaal Length - I <br />kl <br />&I <br />wns ope <br />S:1 QI <br />7•.1 <br />k1 <br />Li <br />ps ope <br />Urlope <br />7-.1 <br />1:1 <br />i wope <br />0 <br />3.0 <br />♦0 <br />S.0 <br />LO <br />70 <br />3.0 <br />LO <br />SA <br />L0 <br />7.0 <br />t0 <br />1 <br />3A <br />L17 <br />S.26 <br />L3/ <br />7S3 <br />L" <br />3JS <br />L76 <br />SAL <br />LSI <br />741 <br />2 <br />3.19 <br />L1S <br />SSi <br />&M <br />L14 <br />2A3 <br />370 <br />4-% <br />S.)< <br />LI4 <br />L" <br />3 <br />3.30 <br />CU <br />SA <br />7.32 <br />LK <br />2.75 <br />3S7 <br />41S <br />S.0 <br />S.1 <br />4.45 <br />4 <br />3A1 <br />474 <br />&Z <br />7.M <br />9.12 <br />2.Y <br />145 <br />4.17 <br />lM <br />S.46 <br />LO6 <br />S <br />3M <br />S.00 <br />U. <br />LS7 <br />10.7 <br />161 <br />313 <br />_ <br />C62 <br />119 <br />S71 <br />1 <br />3A6 <br />526 <br />7.14 <br />93V <br />12.07 <br />239 <br />323 <br />3M <br />4.41 <br />C93 <br />SAI <br />7 <br />3J0 <br />Sad <br />7.60 <br />IGLU <br />U." <br />148 <br />112 <br />370 <br />4.23 <br />cM <br />S.I3 <br />1 <br />1A <br />SA <br />L33 <br />IIS4 <br />1S.91 <br />142 <br />103 <br />am <br />l05 <br />ltl <br />4A <br />9 <br />Ul <br />L.25 <br />9.01 <br />I3.W <br />IL92 <br />234 <br />191 <br />145 <br />190 <br />t,.10 <br />9A5 <br />10 <br />U9 <br />LO <br />tOD <br />IS.00 <br />2333 <br />231 <br />L86 <br />3.X3 <br />3.75 <br />4.12 <br />4.44 <br />11 <br />w <br />7.14 <br />11.11 <br />17AS <br />3043 <br />2.71 <br />172 <br />3M3.61 <br />1" <br />416 <br />12 <br />4A9 <br />7.0 <br />1230 <br />- 2143 <br />43.75 <br />L21 <br />170 <br />3.12 <br />149 <br />150 <br />4 01 <br />
